Removing and Installing AC Shunt Power Directors
Removing and Installing AC Shunt Power
Directors
The amplifiers draw AC power from the coaxial cable. This AC power comes from an
external AC power supply.
WARNING:
When AC is applied from RF ports to units downstream, the downstream
equipment shall also be located in a restricted access location (access restricted
to service personnel).
Power can come from the input or output ports, and each amplifier can pass or block AC
power flow on any port without affecting RF continuity. However, at least one port must
pass AC power to bring power into the amplifier.
To set the power direction, install AC shunt power directors for the ports through which
To set the power direction, install AC shunt power directors for the ports through which
you wish to pass AC.
Note: A red AC shunt power director is included with the unit. The red shunt is used to
activate the port that supplies power. The red shunt should be removed before installing
or removing the amplifier module from the housing.
CAUTION:
RF connectors and housing seizure assemblies can be damaged if AC shunt
RF connectors and housing seizure assemblies can be damaged if AC shunt
power directors are not removed from the amplifier before installing or
removing the amplifier module from the housing.
