Fan Installation

Perform the following steps to reinstall the fan assembly in the repeater housing. Due to a limited amount of space in the back of the repeater housing, you must connect the power cable before installing the fan. To free both hands for easier installation of the power cable, you may want to rest the fan assembly on top of the repeater housing.

1.Connect the fan assembly power cable between the bottom connector of the power supply and the fan assembly connector that extends out the rear (refer to Interconnect Cabling Diagram)

2.Side the yellow lead of the fan assembly power cable containing the thermistor into the thermistor clip (Figure 2-4).

Figure 2-4. Thermistor Clip

3.Using a Torx screwdriver, secure the thermistor clip to the mounting hole located on the transmit radio heat sink with a M5x0.8x8 taptite screw (Figure 2-5).
