44 205486 REV F Operations Manual, HPA2, Compact Outdoor SSPA
6.2.1 Fan Replacement
Older models of the Compact Outdoor SSPA were fitted with a 2-fan cooling fan assembly.
The newer models utilize a 3-fan cooling fan assembly.
While the fan interface connectors for the two-fan and three-fan tray assemblies are identical,
they should not be used interchangeably.
If your Compact Outdoor SSPA was shipped from the factory with the three-fan air intake tray,
any maintenance requiring replacement of the fans should only use the three fan kit (L205192
-1). The three fan kit requires 12VDC directly from the buss bar and draws 5.9A (70W).
If your Compact Outdoor SSPA was shipped from the factory with the two-fan air intake tray,
any maintenance requiring replacement of the fans should only use fan kit L201814-1. This kit
replaces one fan on the fan tray assembly. The two fan kit requires 28VDC from the booster
circuit card assembly and draws 0.7A (19W).
Note: Failure to use the proper fan tray will cause damage to your amplifier!
It is possible to modify an older Compact Outdoor SSPA to be fitted with a 3-fan cooling fan
assembly in place of a 2-fan assembly. This should be done by an authorized Paradise
Datacom technician, using the procedure outlined in drawing number 206573.
6.3 Connector Weatherproofing
As a precaution against water intrusion, all cable connections should be wrapped with
weather-resistant electrical tape, provided with
the unit. Make sure each connector is clean and
dry before applying the electrical tape.
Apply the electrical tape to all MS connectors
and N-type connectors . Starting at the cable
end, wrap the weather-resistant electrical tape
around the connector, overlapping each turn by
half the width of the tape. Continue wrapping
until the connection mating point is enveloped.
Wrap an extra turn around the base of the
connector. Press and smooth the tape with your
fingers to form a good seal. The tape surface
should be uniform in appearance with no visible
gaps or protrusions. See Figure 6-2.
