Mounting Instructions
BM3B battery maintainer is designed to be able to mount to flat surface. The unit has incorporated
two mounting holes at the corners of the unit.
Note:
Always disconnect the maintainer at AC power source and at battery terminal when mounting the unit.
TO MOUNT THE UNIT:
1. Make sure the surface is flat and free of obstruction so the unit can rest flat on the surface.
2. Make sure the unit is disconnected from both AC power source and the battery.
3. Use 8/32 inches (6.35mm) wood screw to mount the unit through the mounting hole.
4. Do not over tighten the screw, it will damage the housing.
WARNING: Do not put the screw through the plastic housing as this will permanently damage the
unit and cause a potential electrical hazard.
