Vertiv Liebert iCOM User Manual

NOTE: Both probes on the 2T sensor must be installed on the same rack.
2. Install the 2T sensor probes the front door of the rack:
a. Using a cable tie, secure the sensor wire so that a probe is approximately 12in. (305mm) from the top and
in the center of the front door. This sensor monitors hot air coming over the top of the rack from the hot
aisle.
NOTE: Do not wrap cable ties around the actual sensor probe. If the rack has no door, secure the probes to the rack at
the side of the front opening.
b. Use a cable tie to secure the sensor wire of the second probe to the front door so that it is centered in front
of the heat generating equipment drawing air.
If the cabinet is completely filled with equipment, determine the center based on cabinet width and height.
c. With probes in place, use cable ties to route the wires neatly up the rack door and into the rack leaving
enough slack in the wire so that the rack door opens and closes without binding or pinching the wire.
d. Using the supplied, hook-and-loop fastener, connect the 2T-sensor housing to the rack in an easily
accessible location and with the sensor number visible.
3. Repeat step 2 until all sensors are installed.

WARNING! Risk of electric shock. Can cause equipment damage, injury or death. Open all local and remote
electric power supply disconnect switches and verify with a voltmeter that power is off before working within
any electric connection enclosures. Service and maintenance work must be performed only by properly
trained and qualified personnel and in accordance with applicable regulations and manufacturers’
specifications. Opening or removing the covers to any equipment may expose personnel to lethal voltages
within the unit even when it is apparently not operating and the input wiring is disconnected from the
electrical source.
Cabling considerations:
• For cable up to 150 ft. (45-m) long, no special considerations are needed.
• Cable 150 ft. (45m) to 300 ft. (91m) require a CANbus isolator.
• For cable longer than 300 ft. (91m), contact the factory.
• The CANbus cable network requires a ground wire.
