Installation of the Local Power Source (LPS) will be dictated by on-site conditions and local
telephone company practices. Refer to
and the following steps to complete the
installation.
1. Install the Local Power Source (LPS) wire run from the GPON 452/454 to the connector
of the LPS via the customer provided PVC conduit (or method used by your local tele
-
phone company practice). ADTRAN recommends using 16 AWG at a maximum of 100
feet (30.4 meters). For alarm signals, ADTRAN recommends using 24 AWG. Do not plug
in the UPS green connector at this time. This will be done after the subscriber’s wire/
cables are terminated during turn-up and testing.
2. If necessary, tie wrap both the ground wire and LPS wire run to the Buried Fiber Drop
riser conduit.
