3-3. Adding Fans to 6612 Convection Cooled Loads
•
Place the 6612 on the end panel away from the RF connection.
•
Remove the 8-32 Torx head screws
around the outside of the bottom panel
and remove the bottom panel assembly.
•
Place the new fan assembly on the 6612.
Use the screws removed from the old
bottom panel assembly to fasten the new
fan assembly in place.
•
The hole patterns are the same. The
electrical components will be installed
after the fan assembly is in place.
•
Place the 6612 back in the upright
position.
•
Remove the roof assembly by removing
the six 8-32 Torx head screws that hold it in place. There are three screws on either end.
•
Fasten the thermal switch brackets in place as shown. The location is important for
proper operation of the fans and the interlock circuit.
•
The interlock consists of a thermal switch
and connecting wires. Solder the wire ends to
the open terminals of the four-pin amphenol
circular connector.
•
Make electrical connections to the load by
using the terminals supplied in the 4 X 4
weatherproof box on the front panel of the
load.
•
Leave the roof off the load until proper fan
operation is verified.
•
Test for proper fan operation by jumping the
terminals of either thermal switch that is
wired in the fan circuit. They have a yellow
dot on them.
•
Place the roof back on the load.
