Removal and Replacement Procedures
NOTE The UPS requires single-phase input power (in contrast to 3-phase).
Single-phase power may be obtained in one of the following ways:
a. Line-to-neutral: 200-240V across a phase wire (hot wire) and a
neutral wire.
b. Line-to-line: 200-240V across two different phase wires (hot wires).
In some countries, the UPS must be supplied line-to-line in order to obtain
200-240V. Other countries require line-to-neutral to obtain 200-240V. In no
case should the input voltage exceed the rating of 200-240V.
Output wiring for worldwide (hardwired) version:
Line (or Line 1): Connect wire to the L1 terminal
Neutral (or Line 2): Connect wire to the L2/N terminal
Earth Ground: Connect the GREEN or GREEN/YELLOW wire to the terminal
marked with the following symbol:
Tighten the terminal block screws to the following torque specifications:
For Line and Ground Terminals: 1.2 - 1.4 Nm (10.6 - 12.3 lb-in)
