The battery enclosure may be bolted down to the floor using the four holes located on the side
flanges. Mounting holes will accept up to 3/8” bolts. Use a thick, wide flat washer as a back up
underneath the bolt head to add to the pull through strength.
The MNBE-B is designed to hold 8 group 31 or group 27 batteries as well as T-105’s or 8
Concorde PVX 3050T(13” tall golf cart batteries).
With T-105’s MNDC250 (sealed)
breaker
You must use sealed AGM or Gel batteries when installing a circuit breaker/disconnect in one of
the side panels as shown above. Circuit breakers make sparks and vented batteries cannot be in
the same cabinet with any device that makes arcs or sparks. A circuit breaker installed as shown
must be inserted in the battery positive lead. Do not install in the negative leg.
Two battery enclosures may be connected together side by side for additional storage. 2” conduit
knock outs are provided on each side of the enclosure to accommodate this configuration. Use a
6” long conduit to connect the two cabinets together.
Battery boxes stacked vertically on top of each other. ¾” pieces of wood are inserted inside the
top panel to support the extra weight and give a place to screw to.
Drainage:
The MNBE is designed to self drain if water enters the cabinet. The enclosure is not tightly
sealed at the bottom, however if the installation limits the self drain feature add drainage holes at
the bottom of the enclosure.
Ventilation:
The MNBE enclosures are designed for sealed batteries. Sealed batteries do not require
ventilation. When flooded batteries are used a spill tray must be provided (Not supplied) and
ventilation of explosive gasses must be directed out the top through the 2” knockout. The
NEMA-3R version does not have a knockout on the top and must be provided as part of the
installation. Powered ventilation may be required to provide proper ventilation.
