For single-phase 208V only, in North America and Japan, utility L2 connects to UPS neutral; for most other countries (200, 220-240V), utility neutral
connects to UPS neutral.

The ground screw on the input terminal block can be used for input ground if an appropriate ring lug is available.

For three-phase, dual input feed, the three-phase input wires can be 5.3 mm

3. Follow the instructions for the input configuration to be used with the UPS:
For single-phase, single input feed, 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, 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, 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.
4. Connect the wires to the terminal blocks according to the following table.
