19.6.4 Installing the Power Supply for the CMMmicro
Install the CMMmicro power converter in only a hut, wiring closet, or weatherized
enclosure.
WARNING!
Although the output of the power converter is 24 V, the 100-W power
rating classifies the converter as a Class 2 electric device. For this
reason, whenever you work on power in the CMMmicro, you must first
disconnect the CD converter from the AC power source.
Perform the following procedure to install the provided power supply.
Procedure 29: Installing the Power Supply for the CMMmicro
1. Connect the 6-ft (2-m) AC power cord to the power converter (but not yet to an
AC receptacle).
2. Select the length of power cord as follows:
a. If either mounting the CMMmicro inside with the power converter or outside
within 9 ft (2.8 m) of the power converter, select the 10-ft (3-m) DC power
cord (rated for outdoor use).
b. If mounting the CMMmicro outside and further than 9 ft (2.8 m) from the
power converter, ensure that this additional length of cord is either UV-
resistant or shielded from UV rays.
