302 Installing the Conduit and Wiring
❑1. Install the conduit and conduit adapters. Refer to the proper installation wiring diagram for your
application (see Table 9, page 10). Read the notes under the wiring diagram.
• The AC Line Input and AC Line Output conductors must be run through separate
conduits.
• All UPS output circuits must be installed in dedicated conduit systems and not shared with
other electrical circuits.
❑2. Make all of the terminal connections inside the external bypass switch (if applicable).
• Refer to the label on the back of the bypass switch’s lower cover.
• Refer to the proper installation wiring diagram for your application (see Table 9, page 10).
• Tighten all connections securely.
❑
3.At the UPS terminal strip, connect the neutral-to-ground (neutral-to-earth)
wire to the proper output terminal before making any other connections to
the UPS.
• For the proper neutral-to-ground (neutral-to-earth) output terminal connection, find your
UPS output configuration in Figure 9.
• The neutral-to-ground (neutral-to-earth) wire is a green and yellow wire labeled WIA-0424.
One end of the wire is already connected to ground (earth) on the UPS terminal strip.
CAUTION!
Before installing the external bypass switch, make sure that the UPS Bypass Switch and the UPS
AC Line Disconnect Switch are both in the “OFF” position.
CAUTION!
Make sure that the keyswitch inside the front door of the UPS is in the “OFF” position.
Make sure that all sources of AC power are shut off (including AC power to the load distribution panel, if
applicable).
