To prevent electrical shock or damage to your equipment, verify that the AC input is
OFF at the service panel and the bypass and AC disconnect switches are in the OFF
position before you connect any wires to the bypass switch terminal strip.
5. Find the terminal strip inside the bypass switch. Using the label
on the back of the switch’s lower front cover panel, wire the
terminal strip and tighten all connections securely. Use copper
wire and the appropriate wire size for the current. See Figure 16
for a sample terminal strip label.

6. Using the installation wiring diagram, wire the UPS-internal
bypass terminal strip and complete the AC wiring.
NOTE Terminal strip connections should be exactly as shown in the installation
wiring diagram to ensure proper phasing. Good ground connections are necessary to
reduce electrical noise and ensure safe operation of the UPS and the load.
7. If your UPS does not have an external battery cabinet(s),
continue to “Phase Check” on page 65.
If your UPS has an external battery cabinet(s), continue to
