1.3.1 Location and Storage
The unit is convection cooled with the air vents located on the sides and top of the unit enclosure. Therefore, it
should be installed in a clean, dry place with enough clearance to allow a free flow of air. Allow at least 4 inches of
space between the unit and the wall or other equipment for portable units. Allow enough space for maintenance on
all four sides on larger units. Never mount one unit over the other, heat rising from the unit may cause premature
failure. Never install the unit near a heat source.
NOTE: If the unit is to be mounted vertically, the surface area
must be capable of supporting at least 4 times the unit’s
weight. (See Table 1-2, page 1-4.) Locate the conduit
knockouts at the bottom, with the mounting slots in the
mounting brackets facing down. Transfer the hole
pattern from the unit to the mounting surface and drill
the holes, refer to dimensions, page 1-5 and 1-7 for hard
wire enclosure. Use at least .25” hardwire (minimum
grade 5) to attach the unit to the surface, with 6.00”
clearance around the unit for air flow.
If the equipment is to be stored prior to installation, it should be stored in a cool, dry, well-ventilated location that is
protected from rain, splashing water, chemical agents, etc. The equipment should be covered with a tarpaulin or
plastic wrapper to protect it against dust, dirt, paint, or other foreign materials.
