Note This product is intended for installation in restricted access areas and is approved for connection using 12 or 14 AWG copper conductors only. The installation must comply with all applicable codes.

Note For central office installations, we recommend using a 6 AWG green ground wire with one end connected to reliable earth. The other end of the wire should be crimped onto the double-hole lug provided in the installation pack. The lug should be secured to the mating holes on the side of the chassis with the two screws included in the accessory pack.

Note If you are installing a redundant power supply, you should attach appropriate-sized spade terminals to the stripped ends of the ground and input wires.

b.Insert the safety ground (green wires) into the DC connector ground connector and tighten the locking screw. Ensure that no bare wire is exposed.

c.Insert the +48 VDC return wires into the DC connectors (+) and tighten the locking screws. Ensure that no bare wire is exposed.

d.Insert the –48 VDC wires into the DC negative connectors (–) and tighten the locking screws. Ensure that no bare wire is exposed.
