Preparing the installation site
Unlike the i3822V, the iPSU must be installed in a sheltered area, either inside the
garage or home. The iPSU with a battery installed weighs approximately 11 pounds.
Make sure that the selected wall stud is strong enough to support the weight.
Locating a proper site
You can mount the iPSU on any flat surface (wood, brick, or stone) and at any height
level, from eye to floor level. Unless it is demanded by the subscriber that the iPSU be
mounted on the floor level, mount the iPSU above the floor level and away from any
areas with a potential for standing water.
The life of the battery is affected by the local environment; select a site that is away
from excessive heat, machinery, and vibration. Locate a stud wall inside the home or
garage that is within eight feet of the nearest electrical outlet (the length of the
supplied power adapter) and strong enough to support 11 pounds (the weight of iPSU
with a battery installed).
Note: Do not use an extension cord.
The iPSU contains live electronics. Any standing water that is above four inches from
the bottom edge of the iPSU can damage the iPSU wiring, which might affect the
performance of the i3822V. The lead-acid battery is sealed and will not be damaged
by the water exposure.
