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

The 15 A 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 a line extender 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.
