9. Use a pallet jack or an adequate number of qualified personnel to lift the DCR Control Panel
Shell onto the secondary Base Plenum-PDX/PCW.
The DCR Control Panel Shell must be aligned with the front of the base plenum and will be
flush with the end of the base plenum.
10. Bolt the DCR Control Panel Shell to the base plenum with the 6 factory-supplied
1/4-20x3/4 bolts.
11. Apply D-shaped gasket to the side of the secondary Top Plenum-PDX/PCW facing adjacent
DCR rack.
12. Install edge guard on the bottom half of the two openings on the secondary Top Plenum-
PDX/PCW.
13. Set the secondary DCR Top Plenum-PDX/PCW on the top of the PDX/PCW and DCR Control
Panel Shell, and secure it with 6 1/4-20x3/4 bolts.
NOTE: Take care not to damage the gasket when applying it and when setting the DCR Top
Plenum-PDX/PCW on the top of the Liebert PDX/PCW and Redundant Control Shell. If the gasket is
damaged, the cooling unit must be removed and the gasket replaced. A damaged gasket will permit
cooling air to escape, which will reduce cooling efficiency, increase energy use and adversely affect
fire-suppression system operation.
4.10 Installing and Wiring Sensors
• DCR Return Temperature Thermostat—Activates emergency fans
• Supply Air Temperature Sensor—For supply air temperature control
• 2T Sensor—Sense temperature of each rack; for load balancing
• Smoke Detector—Senses combustion products in the return air to activate fire suppression
• HVAC Fault/Emergency Fan Control, Thermal unit Shutdown
See Table 11.4 on page 80 for SmartRow DCR field-wiring guidelines
4.10.1 Connect Return-temperature Thermostat,
the L5-20 Receptacle and the Smoke Detector
The DCR Return Temperature Thermostat and smoke detector are factory-installed in the DCR Top
Plenum PDX/PCW. The L5-20 receptacle, which supplies power for the emergency fans, is factory-
installed on the exterior of the DCR Top Plenum-PDX/PCW.
Wiring for the DCR Return-temperature thermostat, smoke detector, and supply power for the
Emergency Fan's receptacle must be connected for these items to function properly. To facilitate this
connection, a factory-supplied harness is located in the Control Panel and Fire Suppression cabinet. The
wiring harness consists of three connector cables:
• 4-pin Smoke Detector connector cable
• 3-pin Emergency Fan supply-power connector (P1)
• 3-pin DCR Return Temperature thermostat connector (P3)
NOTE: The DCR Return Temperature Thermostat is used to activate the emergency fans in the event
of a high return air temperature (98°F [37°C]).
The wiring harness is located in the control panel.
