Discard discharged batteries as soon as possible. Discharged batteries are more likely to leak.
•
Do not store batteries in high temperature areas. Batteries stored in a cold environment should be
protected from condensation during storage and warming. Batteries should be stabilized at room
temperature prior to use after cold storage. Do not install batteries if the manufacturing date on the
label indicates that the batteries are more than six months old.

Locate one plate directly below the other one such that the AC power cord (6.5 feet or 2 meters)

NOTE:
A maximum of four power supplies can be powered from one dedicated 110 VAC, 20 amp
(or 230 VAC, 15 amp) feeder. Use only unswitched receptacles (receptacles not connected
to a wall switch).

Secure the wall mounting plates to a standard 3/4 inch (2 cm) thick plywood mounting board.
Each mounting plate comes with four #10 x 1/2-inch wood screws.
