WARNING: Disconnect primary power prior to servicing.
Section 2 Installation / Initial Turn-On ATLAS Series™
2.12 Install PA and PS Modules
Plug the power supply modules into the slots at the bottom of the cabinet . The
breakers on the front of each power supply should be set to OFF.
!
WARNING:
THE PA MODULES ARE LARGE AND RELATIVELY HEAVY AT SLIGHTLY LESS
THAN 21KG. CARE SHOULD BE TAKEN TO AVOID PERSONAL INJURY AND/OR
DAMAGE TO THE MODULES.
Install the PA modules into the front of the
transmitter cabinet.
Be sure to rotate the module
fasteners fully CCW before inserting. The hose
connections should be near the bottom. Rotate the
front fasteners CW to lock the module in place.
NOTE:
The PA Modules should be placed into the same slot in which they were
tested at the factory. Each module has a serial number tag. This serial number
is recorded on the factory test data sheet along with the appropriate slot num-
ber. Placing the module in a different slot will not cause any harm to the
transmitter but will require more time for module phasing.
Connect the Coolant hoses to the rear of the PA
Modules.
Green hoses on the bottom and blue hoses
on the top. Push the hose coupling on to the module
nipple until it locks into place. Make sure the coolant
valves on the couplers are in the open position as
shown here. Turning the valve at a right angle to the
hose shuts off flow to the module.
!
CAUTION:
FAILURE TO CONNECT THE COOLANT HOSES TO THE MODULE COULD
RESULT IN A POSSIBLE MODULE FAILURE SHOULD POWER BE APPLIED.
