G3ZA■ Precautions for Correct UseWiringUse M3 crimp terminals.
Use wires that withstand a minimum of 70 C.
DIN TrackSecure the DIN Track with screws in at least three locations.
DIN Track: PFP-50N (50 cm)/PFP-100N (100 cm)
Mounting the G3ZAMount the G3ZA as shown in the diagram. First, pull down the DIN Track mounting hook (1) and hook the top of the G3ZA on the DIN Track (2). Then press the G3ZA onto the DIN Track far enough so that it can be locked in place (3) and push the DIN Track mounting hook up to lock the G3ZA in place (4).
Removing the G3ZAUse a flat-blade screwdriver to pull down the DIN Track mounting hook (1) and then pull out on the bottom of the G3ZA (2).
Mounting End PlatesBe sure to mount an End Plate on each side of the G3ZA so that it does not slide on the DIN Track.
To mount an End Plate, hook the bottom of the End Plate on the bottom of the DIN Track (1), place the top of the End Plate on the DIN Track (2), and then pull down on the End Plate. Tighten the screw on the End Plate to secure it.
Note: Always mount one End Plate on each side of the G3ZA.
Installation ExampleWhen installing the SSRs next to the G3ZA, provide sufficient space between the G3ZA and SSRs, as shown in the following diagram.
Reference example: When applying 10 A to the G3PA-210B-VD (a manipulated variable of 100%), separate the SSRs from the G3ZA by at least 20 mm.
Do not touch the G3ZA while power is being supplied.

Safety Precautions for All Power ControllersFor the precautions for individual products, refer to the Precautions for that product.
!CAUTION
■ Precautions for Safe UseOMRON constantly strives to improve quality and reliability. Power Controllers, however, use semiconductors, and semiconductors may commonly malfunction or fail. In particular, it may not be possible to ensure safety if the Power Controllers are used outside the rated ranges. Therefore, always use the Power Controllers within the ratings. When using a Power Controller, always design the system to ensure safety and prevent human accidents, fires, and social harm in the event of Power Controller failure. System design must include measures such as system redundancy, measures to prevent fires from spreading, and designs to prevent malfunction.
1. Do not apply voltage or current in excess of the ratings to the terminals of the Power Controller. Doing so may result in failure or burn damage.
2. Do not use the Power Controller with loose terminal screws. Doing so may result in burn damage due to abnormal heat produced by the terminals.
3. Do not block the movement of the air surrounding the Power Controller or heat sink. Abnormal heating of the Power Controller may result in shorting failures of the elements or burn damage.
4. Follow the Precautions for Correct Use when performing wiring or tightening the screws. If the Power Controller is used with the wiring or screw tightening performed improperly, burn damage may occur due to abnormal heat generated when the power is being applied.
■ Precautions for Correct UseFor details, refer to Technical Guide for Power Controllers.Do not touch the Power Controller or the heat sink while
the power is being supplied or immediately after the power supply has been turned OFF. Touching the Power Controller or heat sink while it is hot may result in burns.
Do not touch the Power Controller LOAD terminals immediately after the power has been turned OFF. Shock may result due to the electrical charge stored in the built-in snubber circuit.
Always attach the cover terminal if the Power Controller has one. Contact with current-carrying parts may result in shock.
Always turn OFF the power supply before performing wiring. Not doing so may result in shock.
Do not allow short-circuit current to flow to the load side of the Power Controller. The Power Controller may explode if short-circuit current flows.
In the interest of product improvement, specifications are subject to change without notice.

Precautions for Correct Use of Power Controllers
Load• Only resistive loads can be connected to the G3PX.• Transformer Loads
The primary side of a transformer is an inductive load. Therefore, do not control it directly.
MountingThe Three-phase, 60-A G3PX weighs 5 kg. Dropping the G3PX when it is being mounted may result in injuries.
Mounting Procedure
Note: In the case of flat mounting, the 30% derating of the load current is required.
1. Installation Space between Power Controllers
Panel Mounting Conditions
2. Relationship between Power Controllers and Ducts (or Other Airflow Obstructions)
3. Ventilation
Note: 1. If the air inlet or air outlet has a filter, clean the filter regularly to prevent it from clogging and ensure an efficient flow of air.
2. Do not locate any objects around the air inlet or air outlet; otherwise, the objects may obstruct the proper ventilation of the control panel.
3. A heat exchanger, if used, should be located in front of the G3PX to ensure the efficiency of the heat exchanger.
• Please reduce the ambient temperature of G3PX.
Note: The rated load current of the G3PX is measured at an ambient temperature of 25 or 40°C.
• The G3PX uses a semiconductor to switch the load. This causes the temperature inside the control panel to increase due to heating resulting from the passage of electrical current through the load. To restrict heating, attach a fan to the ventilation outlet or air inlet of the control panel to ventilate the panel. This will reduce the ambient temperature of the G3PX and thus increase reliability. (Generally, each 10°C reduction in temperature will double the expected life.)
Example: For 10 Controllers with load currents of 20 A,0.31 10 = 3.1Thus, 4 fans would be required.
Note: 1. Size of fans: 92 mm2, Air volume: 0.7 m3/min, Ambient temperature of control panel: 30°C
2. If there are other instruments that generate heat in the control panel other than the G3PX, additional ventilation will be required.
Wiring• Make sure that the lead wires are thick enough according to the
current.• Be sure to turn off power to the G3PX when wiring. The G3PX has
current leakage although the G3PX is turned off if the power supply is connected to the G3PX, which may give an electric shock.
• Do not wire power lines or high-tension lines along with the lines of the G3PX in the same conduit, otherwise the G3PX may be damaged or malfunction due to induction. Be sure to wire the lines of the G3PX separated from power lines or high-tension lines or laid in an exclusive, shielded conduit.
Tightening TorqueApply the following tightening torque.Output terminal:20-A model: 1.47 N·m
40-A model: 2.45 N·m60-A model: 4.12 N·m
Terminal block: Single-phase model: 0.98 N·mThree-phase model: 0.6 N·m
Be sure to protect the terminals with the protective cover after wiring.
Wiring for Error DetectionIf a contactor is employed and operated with the relay output signal of the G3PX for error detection, make sure that the G3PX is closer to the power supply than the contactor.

Instruments
The instruments are used for displaying root-mean-square voltage and current values of the AC circuitry.
Operation MonitoringThe level indicator just indicates the phase of the load and it is not highly precise.
Duty Setting• There is a decrease in ramp if the internal DUTY adjuster is turned
counterclockwise.
• If the External DUTY Adjuster is used, set the Internal DUTY Adjuster to 100%.
CT Unit• The CT Unit varies with the G3PX-series model. Use the following
CT Units in combination with the G3PX models.G3PX-2@0EH Series: G32X-CT@@G3PX-2@0EHN Series: G32X-CT@@HNG3PX-2@0EC Series: G32X-CT@@CG3PX-2@0D@@ Series: G32X-CT@@C
• If any of the following models is used and the actual load current is 50% of the maximum rated load current or lower, increase the number of turns of the wire around the CT Unit.G3PX-20EHN Series (multi-heater open circuit detective models)G3PX-20EC Series (constant current)Three-phase ModelsFor example, make two turns if the actual load current is 50% of the maximum rated load current and four turns if the actual load current is 25% of the maximum rated load current.If the G3PX is a constant current model, do not increase the number of turns of the wire around the CT Unit excessively, otherwise the overcurrent detective function may operate by mistake.
External DUTY AdjusterUse the External DUTY Adjuster with a resistance of 2 k or that with a resistance of 3 k according to the G3PX-series model in use.
Refer to the following combinations.
G3PX-2@EH Series: G32X-V3K (3 k )G3PX-2@0EUN Series:G32X-V2K (2 k )G3PX-2@0EHN Series:G32X-V2K (2 k )G3PX-2@0EC Series: G32X-V2K (2 k )G3PX-2@0D@@: G32X-V2K (2 k )
Base-up Function
EUN, DU, and DH ModelsThe base-up output of the G3PX with a temperature controller output of 0 mA (i.e., the temperature controller is turned off) and that of the G3PX with a temperature controller output of 4 mA are different from each other.
Power Device CartridgeDo not apply power to the G3PX with the Power Device Cartridge dismounted.
Heater Open Circuit Detection
EH and EHN ModelsThe heater open circuit detective function is not available for detecting the phase less than the following.
DH and DC ModelsA voltage output of 70% min. is required for heater burnout detection.
Power Supply
Single-phase Models OnlyDo not apply 200 V to the 100-V terminals, otherwise the thermal fuse of the built-in transformer will be blown and the G3PX will not operate.

Others• It is not possible to use three single-phase models for three-phase
load control.Always use a three-phase model for control of three-phase loads.
• If a three-phase power supply is used for single-phase models operating in parallel, make sure that the two phases supplied to all the single-phase models are the same. Not doing so may result in burnout detection, overcurrent detection, or alarm malfunction. Consult with your OMRON representative if such use is required.
• With three-phase models, the output voltage may become unstable if the balance of a three-phase load is lost. Therefore, use the power controllers with a load current balance ratio of 0.9 or better.
• For three-phase models, do not incorrectly wire the R, S, and T phases of the main circuit wiring. Doing so will cause abnormal operation. After connecting the power controllers, confirm proper operation before using the system.
DH and DU ModelsThe detection sensitivity will differ. Correctly set the star/delta selector.

The 20-A and 40-A models use a triac on output elements. Fundamentally, triacs are easily influenced by power supply distortion, in which case the output may become unstable. (The 60-A models use a thyristor, and so are virtually not influenced by power supply distortion.) Power supply distortion tends to occur if the power supply capacity is insufficient when multiple power controllers are used. In particular, if they are used with three-phase open-delta wiring, power supply distortion may occur across the phases, resulting in malfunctions. If distortion is a problem, use the power controllers together on one phase as shown in the diagram above.
Explanation
Set the output voltage to approximately 50% and check that the voltage is almost the same between the phases. Variation will occur in the output voltage if the phase sequence is incorrect.
