Introduction to Bodine emergency lighting inverters (ELIs)

Application note

Bodine emergency lighting inverters allow selected normal LED luminaires to be converted into code-required emergency light sources.

Depending on your application requirements, there are a variety of inverters at different power ratings. These range from as low as 10 watts all the way up to 400 watts. The 10W inverter is considered unit equipment and can even be installed inside the luminaire.

This design-in guide (DIG) is a good resource to help with selecting the best Bodine emergency lighting inverter for your application. Spec sheets and installation instructions for the various inverter products are also available on our website (www.signify.com/en-us/brands/bodine/products/inverters). These are also good resources for product specifications and proper installation requirements.

Explanation of commercial naming for Bodine emergency lighting inverters

The typical naming convention of a Bodine emergency lighting inverter is shown in the example below.

For an ELI-S-100, the “ELI” means emergency lighting inverter. The “S” signifies that the output voltage is sinusoidal, making it compatible with most LED drivers and fluorescent ballasts on the market today. The “100” signifies the maximum output power.

Features of Bodine emergencylighting inverters

Emergency lighting inverter external connections and wiring

Typical connections to the normal AC LED driver and LED light engine load are shown in Figure 2.

The switched hot connection to the ELI is a feed-through to the emergency luminaires for normal control. The unswitched hot connection is used for battery charging and for sensing the AC line to determine when inverter/emergency operation from the battery should initiate. The dimming connections are for feed-throughs to the emergency luminaires and for power control during emergency operation to adjust the luminaires to the proper output power. There are also internal connections for the battery and other set-up requirements. These will be covered later in this DIG.

Emergency lighting inverter remote mounting distance

Most Bodine emergency lighting inverters can be remotely installed from the luminaire(s) up to 250 feet using Code required wire gauges.

Emergency lighting inverter input voltage

For most Bodine emergency lighting inverters, the unit will automatically detect the input voltage for either 120 or 277 VAC, 50/60 Hz. The only model that does not offer this input voltage auto-detect feature is the ELI-S-400. This model has two separate connections for either 120 or 277 VAC input voltage. As with many Bodine emergency lighting products, the black lead is typically the 120 VAC hot lead and the orange lead is for 277 VAC. The lead that is unused should be capped off independently (see product installation instructions for more details).

Emergency lighting inverter dimming control

There are two primary methods used by Bodine emergency lighting inverters to provide the intended output power to the designated emergency luminaires. The first method involves dip switch settings on the ELI-S-100 circuit board (see Figure 3). To properly use this feature, the luminaires designated for emergency operation must have 0-10VDC dimming control capability. This is becoming a standard option on most LED luminaires. The next step is to determine how many of these luminaires can be backed up by the inverter and what input power is necessary to ensure their light output meets the NFPA 101(R) Life Safety Code® (LSC) required minimum light levels on the path of egress. For example, assume we have several luminaires rated at 100W and operating each of these luminaires at 20W is required to meet the LSC minimums. The installer should set the dimming level dip switches to the configuration shown in Figure 3 for 20% dimming. This means each luminaire will be dimmed to 20% during emergency operation. One would normally assume this means we could connect five (5) of these luminaires to the inverter (20% dimming of a 100W luminaire equals 20W times five luminaires equals 100W). However, since this calculation does not consider the efficiency and power factor of the normal driver installed in each luminaire, this scenario would likely overload the ELI-S-100 inverter. So, in this case, only four (4) luminaires could be connected to the inverter. Newer designs of the ELI-S-100 (those built after 4Q 2018) will indicate an overload with an LED indicator. If this indicator illuminates, one or more luminaires will need to be disconnected from the inverter until the load is within its approved ratings.

Emergency lighting inverter battery installation

Bodine emergency lighting inverters use maintenance-free sealed lead acid (SLA) batteries. Since these batteries use SLA chemistry, they must be charged immediately upon installation and within eight (8) months of the batteries’ manufacturer’s date code. This date code is in the form of MMDDY. So, a date code of 12197 means the battery was manufactured on December 19, 2017, and must be charged within eight (8) months of this date. If your battery has an earlier date code, check the float voltage. If it is less than 12VDC, it should be replaced. Another concern is battery discharge when the unit is not in use (not charging). If AC power will not be present to the inverter for long periods, the battery cable connection to the inverter’s printed circuit board should be disconnected to prevent damage to the battery due to deep discharge.

Each inverter typically uses two 12VDC batteries wired in series for an input voltage to the inverter of 24VDC. See Figure 4 for the typical wiring of an inverter battery. Refer to your product’s installation instructions for more detailed information concerning this and overall product wiring.

Figure 4. Typical Inverter Battery Wiring

Emergency lighting inverter dimming control continued

The second method of inverter dimming control is called auto-dimming. The auto-dimming function is only available on the ELI-S-10, ELI-S-100 (again, those built after 4Q 2018) and ELI-S-250. In this mode, the installer connects as many luminaires to the inverter that require emergency back-up (except for the ELI-S-10, which is only intended to be used with a single luminaire). When AC power is connected to the inverter, it will begin powering up its connected load at approximately a 10% dimming level (about a 1 VDC dimming control output signal) and gradually increase the dimming signal until the output of the inverter is at full power. If too many luminaires are connected to the inverter, even at the 10% dimming level, the inverter will not operate properly until the load is reduced to a level within the inverter’s output ratings. Improper operation is typically indicated by the inverter attempting to operate the load every five seconds (approximately) and then shutting off.

Emergency lighting inverter operation

Now that your inverter is installed per the instructions, AC power is applied to the inverter and the inverter connector is closed or switch SW1 OUPUT ENABLE is in the ON position (available only on the ELI-S-250, see Figure 5), you can now check for proper operation of the load in both normal and emergency modes. In normal mode, the luminaires connected to the inverter should operate like they normally would without the inverter installed. That is, the local switching means and/or 0-10VDC dimmer should still control these luminaires. However, when the inverter is tested by either pressing the test switch or turning off the circuit breaker feeding these luminaires and inverter, the luminaires connected to the inverter should operate at their preset power levels determined during the set up covered in the ELI dimming control section of this DIG. If this is the first test of the inverter, it is a good opportunity to verify the light levels meet the LSC requirements. As with any emergency lighting device, it should be tested for 30 seconds once every 30 days and for 90 minutes once a year. This is the code-required testing necessary to ensure your emergency lighting system is operational.

Figure 5. ELI-S-250 Circuit Board Detail

Once the batteries are installed and the inverter wiring is complete, AC power can be applied, and the inverter connector can be closed. This will enable battery charging and apply AC power to the connected load. For the ELI-S-250, there is no inverter connector. To enable the inverter, toggle switch (SW1) on the circuit board must be in the ON/OUTPUT ENABLE position (see Figure 5).

Emergency lighting inverter electrical and thermal specifications

As noted previously in this document, Bodine emergency lighting inverters provide nearly sinusoidal output voltage to the load in the event of an AC power outage. In addition to this sinusoidal voltage specification, these inverters also provide the following output regulation:

• Output voltage regulated to ±10% for both 120 and 277 VAC.• Output frequency regulated to ±5% for 60 Hz.

The inverter ambient temperature ranges are as follows:

Inverter Ambient Temperature Range

ELI-S-10 0 – 55°C

ELI-S-20 0 – 50°C, 20W output; 0 – 45°C, 25W output

ELI-S-100 0 – 40°C

ELI-S-250 20 – 30°C

ELI-S-400 20 – 30°C

Other emergency lighting inverter features

All Bodine emergency lighting inverters are UL Listed to UL 924 and CSA C22.2, No. 141 for use in the U.S. and Canada except for the ELI-S-400, which is ETL Listed to these same standards. They are also provided with a charging indicator light/test switch that can be used for quick testing of the inverter operation in emergency mode. These inverters are for indoor or damp location use. They are not for use in wet or hazardous locations.

As with many higher power inverters, their enclosures and contents are much heavier than typical unit equipment. For example, the ELI-S-400 weighs nearly 100 lbs. A mounting shelf capable of supporting the weight of the inverter is necessary. Steps should be taken to ensure the inverter is securely mounted and adequately supported. Keep in mind, mounting hardware is typically not provided with the inverter. However, there are fastener keyhole knockouts on the back of the inverter enclosure to permit securing of the enclosure to a rigid surface like a cinderblock wall (see Figure 7).

Figure 7. Typical Inverter Enclosure Keyhole

Mechanical mounting

Power vs. apparent power for an inverter

The power rating of an inverter assumes a load with unity, or 100%, power factor (resistive load). So, for example, an ELI-S-100 would theoretically provide 100W to a purely resistive load.

As we know, most connected lighting loads, even those using high efficiency LED drivers, do not exhibit unity power factor. In fact, there are certain conditions where the lighting load power factor and efficiency are not even 0.9, or 90%. For example, whenever an LED driver is dimmed, its loading characteristics change and its power factor and efficiency reduce. In fact, the type of dimming, linear or logarithmic, can affect the power factor and effiicency as well.

This is where understanding the rating of the inverter product is critical. For most of our inverter products, the "power" rating is provide for a load unity power factor. If the load's power factor is less, then the "power" the inverter will provide is apparent power with units of volt-amps (VA). Looking again at the ELI-S-100, if the load's power factor is 0.9 (lagging or leading), the total apparent power would be 100VA, with only 90W of true power being delivered to the load. This must be a consideration in the lighting design since this could reduce the number of luminaires that can be connected to the inverter.
