Location

For maximum safe operation, choose a location which is free of excess moisture, dust,
combustible material and corrosive fumes. Also, avoid locations where temperatures are high
or where liquids will drip on the charger. Do not obstruct the ventilation openings. Follow charger
warning label when mounting on or over a combustible surface. The recommended charger
mounting location should provide a radial distance of at least 28 inches away from the closest
top edge of the battery.

distance between two chargers must be 12 inches.
The charger will be installed with four 5/16 inch bolts or with the bracket supplied. See the
Mounting Dimensions section at the end of this manual for proper bolt pattern. Charger should
