Dual input utility
On request, the UPS can be delivered for
Dual Input Utility.
Two independent lines (F2 and F3)
supply separately the rectifier and the
Bypass inputs
With this configuration, when the
rectifier-input fuses are opened, the
Automatic Bypass and the Manual
Bypass are supplied by the other line.

Connect wire to the Terminals by using
appropriate tools and appropriate torque.
Torque specification for Input / Output and DC
power connections on Terminals: Section 3.8.1.
Max. rating X1, X2, X3 & X4 terminals: 2 x AWG 4/0 - Use 167°F (75°C) copper wire
NOTE !
For UPS correct operation, the input utility phase rotation must be clock-wise.
Inside the UPS, all neutrals N1 and N2 are connected together.
This UPS is designed to operate in a wye-configured electrical system with a solidly
grounded neutral.
