1. Remove the shorting busbars
from the terminals labeled L1,
L2, and L3 in the Wiring
Diagram, above.
2. For Rectifier input, refer to the
"Dual-Input terminal block" in
the Wiring Diagram, and
connect the cables from the
upstream feeder panel:
– Phase A to rA
– Phase B to rB
– Phase C to rC
– Neutral to N
– Ground to PE (next to pA).
3. For Bypass input, refer to the
"Dual-Input terminal block" in
the Wiring Diagram, and
connect the cables from the
upstream feeder panel:
– Phase A to bA
– Phase B to bB
– Phase C to bC
– Neutral to N
– Ground to PE (next to pA).

Output Connections

NOTE: The UPS has two output
terminal-block sections,
"always-on" and "programmable/
controllable." The always-on
connections are listed first, and the
programmable connections are
listed inside parentheses.
4. Referring to the Wiring Diagram
above, connect the cables from
the UPS to the downstream
feeder panel on the panel board
main breaker:
– Phase A from A (pA) to
Phase A on panel.
– Phase B from B (pB) to
Phase B on panel.
– Phase C from C (pC) to
Phase C on panel.
– Neutral N (N) to the neutral
bus on panel.
– Ground from PE (stud next to
C) to the ground bus on
panel.
5. Replace the conduit box cover
and secure it.

POWERING THE UPS
NOTE: Do not start the UPS until
after the installation is finished, all
UPS wiring is complete, and all
access panels removed for
installation are replaced and
secured on the UPS.
1. Close the upstream feeder
breaker for the UPS rectifier
and, for dual-input
configuration, close the
upstream feeder breaker for the
UPS bypass.
2. Close all downstream breakers
including distribution-panel
main breaker and/or branch
circuit breakers and, if included,
distribution breakers on a POD.
With all the breakers closed, the
UPS starts and performs
boot-up system checks for 20
to 30 seconds.
If custom parameter settings
are needed for this installation/
application, refer to appropriate
information in the Installer/User
Guide, and make the changes.
