1. Connect the power cables of the adapter to the Phase A, Neutral and Ground output of each UPS. 2. For NX Series UPS except for NXr, connect the LBS cable (with two DB9 ports) to COM1 of the LBS Signal Adapter; for NXr UPS and APM UPS, connect the end of the LBS cable (with a DB9 port and an RJ45 port) with DB9 port to COM1 of the LBS Signal Adapter. 3. For NX Series UPS except for NXr, connect the other end of the LBS cable (with two DB9 ports) to X4 on the parallel board (UHW241M3) in the UPS; for NXr UPS and APM UPS, connect the end of the LBS cable (with a DB9 port and an RJ45 port) with RJ45 port to the J4 port of the bypass module ! WARNING Installation by qualified electrical personnel only- hazardous voltage may be present at the UPS output connectors. of the UPS. 4. Connect the communication cable (up to 492 ft. [150m]) to the COM2 interface of each LBS Signal Adapter. 5. The switch of both LBS signal adapters should be in the right position (see Figure 4).
