Upgrading Existing Housing Seizures
The GainMaker System Amplifier modules have a higher current-carrying capacity
than some earlier amplifier module products. If you are replacing an earlier amplifier
module (SA II, SA II+, or SA III) with a GainMaker System Amplifier module, you
will need to upgrade the housing base to handle the higher current demands.

will need to upgrade the housing base to handle the higher current demands.
The 15 A amplifier housings have silver-plated 0.063 in. diameter pins in the seizures.
The plastic material in the seizures and anvils are glass-filled in order to handle the
higher AC currents, as well as higher temperatures.

To Install the New Housing Seizures
Complete the following steps to upgrade amplifier housing to 15 A current capacity.
Important: The power shunts must be removed before installing the unit into a
powered housing. With shunts removed, it reduces the power surge to the
components and F-connectors.

CAUTION:
RF connectors and housing seizure assemblies can be damaged if AC shunt
