General Safety
The charger may only be used for the specified battery types.
This battery charger is supplied with pre-set charging curves
that are adapted for the battery types listed in figure 1.
Always contact the battery manufacturer to verify that the
charging curve is appropriate.
Hydrogen gas is generated when charging batteries, which
can cause an explosion.
During and immediately after charging, batteries may not be
placed in the vicinity of sparks or open flame.
Do not use the battery charger if it is damaged. Do not
touch damaged components. Turn off the input AC voltage
immediately and contact service personnel.
The battery charger has high voltage inside the charger case
that can cause personal injury or death. The metal casing
may only be opened by authorized service personnel.
Disconnect the battery and input AC power before carrying
out maintenance or cleaning the battery charger.
The Battery charger must be connected to an earth
grounded AC input source.
Batteries should only be charged in a well ventilated area.

Installation
Initial Installation
The AC input source to which the charger is to be connected must be
capable of supplying the current specified on the charger nameplate.
Avoid the use of extension cords with the charger. The use of an
improper extension cord could result in a risk of fire or electric shock.
Locate the charger cord such that it will not be stepped on, tripped over
or otherwise subjected to damage or stress.
Do not operate this charger if it has been dropped or is visibly damaged
in any manner; return to manufacturer for service.
The battery charger should be installed indoors in a low humidity and
low dust/airborne particle environment.
If several battery chargers are to be installed next to each other, they
may not be located so that warm exhaust air from one battery charger
blows into the air intake of another battery charger.
Install the battery charger so that gasses from charging battery do not
get sucked in by the battery charger fan.
The battery charger may be mounted horizontally, or suspended on a
wall with the accompanying bracket. When mounted on a wall the
charger should be placed horizontally to prevent the effects of moisture
and dirt. This charger is not intended to be mounted on mobile
equipment.

CHARGER ONLY ON CIRCUITS WITH BRANCH CIRCUIT PROTECTION
(CIRCUIT BREAKER OR FUSE) OF A MAXIMUM OF 20 AMPERES IN
ACCORDANCE WITH THE NATIONAL ELECTRIC CODE, ANSI/NFPA 70
AND ALL LOCAL CODES AND ORDINANCES.
