Section 2 Installation
Maxiva ULX COFDM Series
The transmitter is shipped from the factory with jumpers in the RF Mute interlock posi-
tions on J2 which will allow the transmitter to operate without external interlock con-
nected.
2.10 3 Port Patch Panel Connections
Refer to the Electrical Installation drawing for Patch Panel connections.
!
CAUTION:
ALWAYS SHUT THE TRANSMITTER OFF BEFORE REMOVING THE PATCH PANEL
TO PREVENT POSSIBLE DAMAGE TO THE CONTACTS.
2.11 Initial Cooling System Turn ON
The liquid cooling system (external to the transmitter) consists of a one or two fan air
cooled heat exchanger (depending on model), two pumps and an integrated electrical
control system. Typically, cabinets with eight PA modules or more will use a two fan
heat exchanger unit. Cabinets with less than eight modules would use a single fan fan
unit.
Fan control is by an electronic controller. The controller automatically turns fans on and
off according to sensed temperature in the cooling system piping. Additionally, each fan
can be turned off by an isolator switch on the heat exchanger to allow for maintenance.
