5. Follow the instructions for the input configuration to be used with
the UPS:
For single-phase, single input feed (see Figure 29), the input bypass
terminal block is factory-wired. The L1-JP and L pins are connected
by a short jumper wire, and the bypass is connected to the input
terminal block's L1 automatically.
For single-phase, dual input feed (see Figure 30), remove the short
jumper wire connecting the L1-JP and L pins so that you can
connect the second feed to the input bypass terminal block later in
this procedure.
For three-phase, dual input feed (see Figure 31), remove the short
jumper wire connecting the L1-JP and L pins so that you can
connect the second feed to the input bypass terminal block later in
this procedure. Only a Y-type (star, 5-wire) input is supported. A
delta (4-wire) input is NOT supported. Connect 380–415V L to L,
220–240V L to N. 208/120V three-phase input is NOT supported.
NOTE A three-phase, single input feed configuration (jumpering one of the phases of a
three-phase input to the bypass input) is not recommended. Wire sizing and upstream breaker
sizing would need to be similar to a single-phase input.
NOTE Neutrals are bonded inside the terminal block. Wire the input and bypass terminal
blocks so they share the same ground and neutral and have inputs of the same frequency.
NOTE Install no more than one wire per terminal.
