Unpacking and Inspection
Unpack and inspect the UPS and its accessories,
shown at right
1. If any problem is found, file a damage claim with the
carrier immediately and send a copy to Vertiv at:
Vertiv
1050 Dearborn Drive
P.O. Box 29186
Columbus, Ohio 43085 USA
2. Check the accessories and models against the
delivery list. If any problem is found, notify your local
Vertiv representative immediately.
Single-Input Configuration
1. Remove the conduit box cover to gain access to the
input and output terminal blocks.
2. Remove the knockout plates and attach the
conduits to the rear of the conduit box.
Hardwire Connections—UPS Input
3. Leave the shorting busbars in place on the UPS
input terminal block.
4. Using Figure 1, make these connections:
• Phase A cable from the upstream feeder panel
to UPS Jumper 11
• Phase B cable from the upstream feeder panel
to UPS Jumper 12
• Phase C from the upstream feeder panel to
UPS Terminal 13
• Neutral from the upstream feeder panel to UPS
Terminal 14 or 15
• The safety equipment ground cable from
upstream feeder panel to UPS ground stud 10
Hardwire Connections—UPS Output
The UPS has two output terminal block sections, one is always on and the other is programmable/controllable.
These instructions will list the always-on connections first, followed by the programmable connections inside
parentheses.
1. Using Figure 1, make these connections:
• Phase A cable from UPS Terminal 4 (9) to the downstream distribution panel Phase A on the panelboard main breaker
• Phase B cable from UPS Terminal 3 (8) to the downstream distribution panel Phase B on the panelboard main breaker
• Phase C cable from UPS terminal 2 (7) to the downstream distribution panel Phase C on the panelboard main breaker
• Neutral cable from UPS terminal 5 (6) to the downstream distribution panel neutral bus
• The safety equipment ground cable from UPS Ground Stud 1 to the downstream distribution panel ground bus
2. Replace the conduit box cover and secure it.

Dual-Input Configuration
Dual input configuration for the UPS requires that both feeds be from the same source.
1. Remove the conduit box cover to gain access to the input and output terminal blocks.
2. Remove the knockout plates and attach the conduits to the rear of the conduit box.
Dual-Input Hardwire Connections—Main Input
3. Remove the shorting busbars from the UPS input terminal block on Terminals 11, 12 and 13
Dual-Input Hardwire Connections—UPS Rectifier Input
4. With the shorting busbars removed from the UPS input terminal block, using Figure 2, make these connections:
• Phase A cable from the upstream feeder panel to UPS Terminal 11
• Phase B cable from the upstream feeder panel to UPS Terminal 13
• Phase C from the upstream feeder panel to UPS Terminal 15
• Neutral from the upstream feeder panel to UPS Terminal 17
• The safety equipment ground cable from the upstream feeder panel to UPS ground stud 10.
