Lightning Protection

DC feeds to the SDR need to be surge protected at the SDR.  The Surge protector is mounted on a galvanised plate bonded to the lightning conductor.

Mount

The M4 plate should be drilled as shown below.

On a plate mounting installation fit the box to the wall using the following procedure:

1. Remove the top of the enclosure (4* M4 countersunk screws).

2. Attach the enclosure to the plate using M4 screws. (two holes).

Wiring

Now connect the 48volt power cable using the following procedure.

1. Screw the protection module into the box (position 4). Ensure that the surge and output ends of the board are correctly orientated.

2. Pass the cable ends through the rubber grommets and terminate the surge and protected cables on to the module as follows. (refer to lid)

3. White or blue to +/-.

4. Black to GND

3. Tighten the Glands around the cable to provide a good environmental seal.

4. Screw the lid into place with the four M4 countersunk screws ensuring the rubber weather seal is located in its groove.
