Owner's Manual
 The inverter will automatically shut down if the temperature is below -20ºC (-4ºF).
Protect from extreme cold exposure if this is undesirable.
 Enclosure ventilation is to be provided such that the following guidelines are
satisfied.
o Provide a minimum of 12 inches clearance to the bottom air inlet filters.
o Provide a minimum of 6 inches clearance to the outlet side vents.
o Use in a well-ventilated area within the maximum ambient temperature
rating.
 If the inverter is installed in a small structure or out building, the structure must be
provided with top and bottom venting of at least 100 square inches at each
opening.

3. Mounting

 The enclosure, having a NEMA 1 rating, is designed for indoor installation.
 The enclosure is provided with four mounting feet with 0.281" dia. mounting
holes.
 For mounting to a 0.10" thick metal surface, use M6, ¼-20 or ¼-28 bolts grade 3
or higher with nuts and flat washers.
 For mounting to concrete, use M6 or ¼" bolts using concrete anchors with an 800
pound or greater tension rating.
 The required bolt length is such that the internal threads need to be 100%
engaged.
 The enclosure is to be oriented with the conduit openings facing toward the floor.

4. Electrical Connections

 Connections are made to the unit via the holes in the bottom of the enclosure.
 Holes are sized for 1.5'' rated conduit. Wiring methods in accordance with the
National Electrical Code, ANSI/NFPA 70 are to be used.
 It is recommended that at least 12" of flexible conduit be used below the inverter
to make alignment easier.
 Cutting additional holes in the enclosure is not recommended and voids the
warranty on the enclosure against corrosion and water damage. Any damage to
the electronics caused by the modification will be your responsibility.
