Grounding ODU

Every ODU installed into the Microwave Radio Network will need to be connected to a Lightening

Grounding system .A minimum 25mm Grounding cable to be run to the closest Lightening Bar or Grounding

structure. If there is no available lightening protection grounding bar the ODU can be grounded to the

structure, either using a angle tower adaptor or bolted directly to the structure, all grounding connection

will have electrical bonding plate applied and all paint/grease removed from the contact point.

DC Power Connection

DC cable type

Black or White 2 core electrical flex is is to be used between the RIM and DC power supply,

normally the color code for DC is Black & Blue, (Black ) +ve connected to the buss bar ,(Blue) –ve

terminated to MCB ( Main Circuit Breaker), Any color conductors can be used but they need to have the

correct color heat shrink applied to the exposed ends to hide the incorrect color , example black heat shrink

over brown color conductor.

DC cable size

1.5 sqmm minimum for dc cable run’s less than 10m , for cable run over 10 m ,2.5 sqmm cable to be

installed.

Circuit Breakers

Normally most of Mobile Operator require different standard of this MCB , but there is a main

supplier in the market , which is Merlin Gerin “C” Curve MCB ,only to be installed into 19 Inch rack DC

Distribution, second supplier is Moellor “C” Curve MCB only to be installed inside the Eltek DC Distribution ,

Other type

can

be

used

but

not

required

1+0 XPIC Modular /Compact link MCB rating 6A or 10A

1+1 XPIC Modular/Compact link MCB rating 2x6A or 10A

When the Protected link is to be installed , the installer must ensure that the A leg DC MCB and B leg DC

MCB are not located right beside each other, put as much as separation as possible between them, this is

used as protection against accidentally leaning or dropping tools on to the DC Distribution panel and both

DC feeds are switches off.

DC Connection

Equipment end of the Flex cable must be soldered into the DC connector pins , making sure not

stray copper strands are present that could in the future short out to the case. MCB/Grounding end, each

end of the exposed flex cable , black and blue need to be crimped into a ferrel of the correct size, these

ends are then inserted into the MCB (Bule) –ve and Black +ve into the buss bar.

RIM DC Power connector

Input Voltage Range 40.8‐57.6 Vdc (Positive Ground) , Each RIM card Is protected internally by 3A

125V very fast blow Fuse, Note this not soldered and field replacement.

Link Commissioning

The Link commissioning engineer must be familiar with Siae SCT/LCT or WebLCT software and how

to set up the Siae ALCplus2 .The Link commissioning are required as the following

1. Pan and Tilt antenna for the Maximum Receive Signal Level

2. Ensure the Receive Level meets the specified level in the Link calculation sheet

3. If specified level is not achieved +/‐ 3dB variation from the value in a link calculation are acceptable

Link Commissioning Pan & Tilt adjustment for integrated antenna solution please also refer to the

manufacture installation instructions.

Link Commissioning RSSI

Below is the a graph of received signal RSSI which is plotted against voltage, this voltage reading is taken

from ODU’s BNC connector. An analogue 0‐3 volt Multi Meter is recommended for taking these

instruments as it is response time quicker than a digital multi meter (DMM) and easier to get the peak

receive level.

Field Engineer can also monitor the RX level by monitor at the screen of software WeBLCT

Please note that Maximum Receive Level of ALCplus 2 must not strong over than ‐20 dBm to avoid the

situation of

RX

saturate.
