2.7 Cooling Fan Installation
• This procedure requires a service power supply (for example, an APP 9015S or APP 9022S) to maintain
power to the cable plant while fan is being installed.
• The fan kit for PWE-3, 4, 6, and 8 enclosures includes a fan assembly with a single fan. The PWE-9
and PWE-D36 enclosures’ kit includes a double fan assembly. The installation and wiring procedures,
however, are identical.
NOTE:
Tools Required:
• Phillips Screwdriver
Installation Procedure:
1. Attach the fan assembly to the two pre-drilled holes located in the upper, right, rear of
the enclosure using the two #6-32 x 3/8" (9.5mm) Phillips screws provided. Make sure
to orient the fan assembly so that the exposed fan is up and the fan guard is down, as
shown. Screw the screws in from the outside of the enclosure.
2. Plug one end of the fan’s Y cable into the SPI wire. Plug other end of the Y cable into the
power supply’s OUTPUT 1A.
3. Position thermostat away from power supply, as shown.
