Note
PA cabinets, with eight or less PA modules built after May 2011 use modified IPA modules. These IPA
modules can only be installed in slots 9 & 10. All other transmitters use IPA (driver) and PA modules that
can be placed into any of the IPA (driver) or PA module slots but it is advisable to place them in the same
location in which they were tested. The module location is given in the factory test data that ships with
each transmitter.

Caution
IF THE MODULES DO NOT SEAT WITH MODERATE PRESSURE REMOVE
THE MODULE AND CHECK FOR INTERFERENCE. IF MISALIGNMENT IS
SUSPECTED SEE THE MODULE/RACK ALIGNMENT PROCEDURE IN
SECTION 5. DO NOT FORCE MODULES INTO THE RACK AS THIS MAY
CAUSE DAMAGE TO THE COOLANT OR RF CONNECTORS ON THE BACK OF
THE MODULE OR IN THE RACK.
Warning
THE MAXIVA PA MODULES ARE DESIGNED TO HANDLE VERY HIGH TEMPERA-
TURES AND MAY BE EXTREMELY HOT, UP TO 32
O
C (90
O
F) ABOVE ROOM TEM-
PERATURE. DO NOT TOUCH THE MODULES WITH BARE HANDS AFTER THE
TRANSMITTER HAS BEEN RUNNING. SPECIAL GLOVES CAN BE PURCHASED ,

Note
Each PA module that is installed may introduce air into the system. The system will likely need to be
recharged after modules are installed. The site glass should be checked for fluid level and for air bubbles
prior to turning on the transmitter RF. Low coolant level or bubbles in the sight glass indicate that the
cooling system needs to be recharged.
