Installing the A12B

Mounting the A12B
When mounting the A12B in any configuration, consider the size and weight of the charger. The wall and/or floor
must be able to support the weight of the charger, as well as an additional safety factor. Refer to data sheet to
verify the weight of the charger and the method of mounting using Table 3 below. The location chosen for the
charger should be within an ambient temperature range of 32˚F to 122˚F (0˚C to 50˚C) with a non-condensing
relative humidity no higher than 95%. The charger should be mounted in an area free of explosive materials and
away from any liquids. The A12B utilizes convection cooling so a clearance of at least 6 in (152 mm) of free air
must be maintained on the top, bottom, left and right side for cooling air. Maintain 36 in (914 mm) or more of
clearance at the front of the charger in order to allow for operation and maintenance. The bolts or screws used
to secure the charger should be sufficient length to assure a vibration-free mounting. The preferred fastener is a
machine bolt backed with a flat washer, lock washer, and nut. All hardware should be corrosion-resistant.
