5 POWER CONNECTIONS
5.1 Power Connections to Liebert PDX/PCW
Provide input power to the Liebert PDX/PCW on its own dedicated circuit based on the specific Liebert
PDX/PCW configuration requirements. Input power to the Liebert PDX/PCW must not be connected
through the 225A 3PH or 125A 1PH load center in the DCR Control Panel and Fire Suppression System.
Refer to the Liebert PDX/PCW user manual that shipped with the unit and is available at
http://www.VertivCo.com/en-us/support/.
For electrical and piping connections, the Liebert PDX/PCW can be top-fed, bottom-fed or a combination
of the two. Connections are made through the knockouts in the bottom of the Liebert PDX/PCW electrical
panel/box. For top access, power wiring is routed through the Liebert PDX/PCW top piping chase.
NOTICE
Risk of improper power input. Can cause equipment damage or degraded cooling.
The Liebert PDX/PCW must be powered separately by a dedicated circuit. Power must not be
supplied from the 225A 3PH or 125A 1PH panel, in part because of potential electrical noise
problems.
5.2 Input Power Wiring Alternatives to DCR Control Panel and Fire Suppression
System and Rack Equipment
The load-distribution center located inside the DCR Control Panel and Fire Suppression System requires
connection to either a 120/208VAC, 3-phase, 5-wire connection, or a 120/208VAC, 1-Phase, 4-wire
connection depending on the phase of the load-distribution center selected.
Two 120 VAC, 15 A branch breakers are supplied for:
• DCR Control Logic/Emergency Ventilation Fans
• Fire Suppression System
The user must supply branch breakers, whips and wiring for all rack equipment, including optional rack
PDUs, rack UPSs and general connectivity.
The SmartRow DCR Fire Suppression system and the Control-logic/Emergency-fan circuits must be
connected to an on-line, double-conversion UPS power source to ensure that the Fire-Suppression
system, Control Logic and Emergency ventilation fans do not lose power in the event of any type of power
interruption. The remote emergency-power-off (REPO) switch for the UPS may be a normally-open (N/O)
or normally-closed (N/C).
NOTE: The connection requirements to the SmartRow DCR for each system is different. UPS systems
with a N/O REPO switch must tie-in to terminals 25 & 26A, and the jumper between terminals 21 and 22
must be removed. UPS systems with a N/C REPO switch must tie in to terminals 25 & 26
(See the figure "SmartRow DCR control logic" in
Technical-installation Illustrations on page 81). It is
critical that this UPS is connected to the system correctly.
