4.3.1 Tools Required for Installation
• Small, non-conductive tool for setting control DIP switches
• Medium flat-head screw driver for opening electric panel protective dead-front.
• Cutting tool to trim cable ties
• Small Phillips-head screwdriver to open 2T housing
4.3.2 DIP Switch Settings
The individual 2T rack sensor must be given a unique address on the CANbus cable run to the
associated Liebert CW
™
unit. DIP switches are used to give the 2T sensor its unique address. It is
important to confirm that the DIP switches have been set correctly using the below table. Although it
is not required, it is recommended that the DIP switch sensor number settings correspond to the
number of 2T sensors on the CANbus run. For example, if there are only four 2T sensors used for a
particular Liebert CW unit then the individual DIP switch settings should correspond to address #1,
#2, #3 and #4. If the DIP switches are not set correctly, the control will not operate properly.

Set 2T Rack Sensor Identities - DIP switch settings
1. Confirm that the DIP switches are set correctly for all 2T sensors.
2. Apply numbered stickers to the sensor housings, corresponding to sensor chain position.
3. Based on the sensor number, use the included DIP switch tool to set the DIP switches according to
Table 22. If the settings are difficult to make through the opening in the housing or if the hole is
not present, open the case by removing the three Phillips-head screws. Reassemble housing once
the settings are made.
