XW Solar Charge Controller Installation
4–4 975-0239-01-01
If using “sealed” batteries, the controller can be mounted in the same enclosure as long as
it is adequately ventilated.
For optimal and safe operation, ensure there is adequate clearance around the XW Solar
Charge Controller. See Table 4-2. If clearances are reduced below these minimums, rated
performance may not be achieved.
WARNING: Explosion/Corrosion Hazard
To reduce the risk of fire or explosion, do not install the XW Solar Charge Controller in sealed
compartments containing batteries or in locations that require ignition-protected equipment.
To reduce the risk of corrosion from hydrogen-sulfide gas vented by batteries, do not install the XW
Solar Charge Controller in sealed compartments containing batteries.
Table 4-2 Minimum Clearance Requirements
Location Minimum Clearance
Above 6 inches (150 mm) When units are mounted to the side of the power distribution
panel in a vertical stack, the topmost unit must maintain the minimum clearance to
the nearest surface.
In front Sufficient room to allow for easy access to read the display, to prevent accidental
contact with the heat sink, and to perform maintenance.
On sides 6 inches (150 mm) on at least one side of the overall assembly. A maximum of two
units can be mounted side by side or side mounted against the power distribution panel.
In both configurations, the minimum clearance around the outermost unit must be
maintained.
