3.3 AC Input Connection
The AC input for the BNx000 is made through a fully shrouded pluggable cable which plugs into
the AC PWR CONNECT plug (P1). The cable allows connection to either 120 VAC or 240 VAC
nominal input. The BNx000 power supply must be configured for proper VAC input prior to
connection or damage to the system will occur (see section 3.3.3, AC Input Safety Precautions).

3.3.1 Configuring VAC Input
All BNx000 power supplies are factory set for 120 VAC input (102-138VAC at 50 or 60Hz). To
verify 120 VAC input setting:
Locate the VAC SELECT jumper (J5)
Verify that J5 is in the UP position for 120 VAC input
The BNx000 will also operate with a 240 VAC (195-264VAC at 50 or 60Hz) input. For 240 VAC
input:
Reposition the VAC SELECT jumper (J5) in the DOWN position or remove it before
energizing the power supply.
3.3.2 Wiring the AC Input Power Cable:
The AC Input Power Cable (part #00518) is included. Connection to the harness should be
made via wire nut to an appropriate power source. AC mains wiring should be no smaller than
14 AWG. Wire the cable as follows:
