SW Series Inverter/Charger

Part No. 2031-5

Rev. C: February 2001

Use 1/4" minimum diameter bolts for mounting. The mounting must be capable of supporting twice the
weight of the inverter in order to comply with UL 1741. If this unit is used in a mobile application (i.e. RV,
Boat) secure the inverter to a shelf or deck to prevent movement. Place flexible washers on the mounting
screws or bolts between the shelf or deck and the inverter chassis to reduce vibration.

VENTILATION

Installation of the inverter in a properly ventilated enclosure is necessary for efficient operation of the unit.
The inverter’s thermal shutdown point will be reached sooner than normal in a poorly ventilated
environment and will result in a lower peak power output, reduced surge capability, and potentially shorter
inverter life.

Note: Do not operate the inverter in a closed-in area or restrict ventilation in any way.

Testing has shown that the volume of the enclosure is not as important as the overall ventilation. A
minimum airspace clearance of 1½ inches around the top and bottom and 3 inches of clearance at the left
and right sides of the inverter will provide adequate ventilation. Because the top and bottom of the SW
Series chassis is not vented, clearance between the enclosure and the top of the inverter is not critical. A
fresh air intake port should be provided directly to the left side and an exhaust port on the right side will
allow cool outside air to flow through the inverter and back out of the enclosure.

AC WIRING

This section describes AC wiring requirements and recommendations; including AC connections; wire
sizing; overcurrent devices; GFCIs; external relays; hookup procedure; and neutral-to-ground switching.
Your local electrical code and the National Electrical Code (NEC) define the standards for AC installation
wiring, but there are still many installation variables to be considered. Consult the local code and the NEC
for the proper wire sizes, connectors and conduit. All installations should meet all local codes and
standards and be performed by qualified personnel such as a licensed electrician.

AC INPUT AND OUTPUT CONNECTIONS

A six position terminal block is provided to make the AC connections. The terminal block is located on the
left-hand side of the inverter, enclosed under a cover plate (See INTERNAL COMPONENTS AND
INDICATORS
on page 13 for location.). The terminal block can accept up to # 6 AWG stranded wire and
is used to hardwire all AC connections. For 120 VAC inverters, we recommend 6 AWG (THHN) wire for
full utilization of the inverter’s 60 amp AC pass through capability. The code requires that disconnect
switches be provided in the AC input and output wiring circuits. AC circuit breakers in an AC load center
can be used to meet this requirement. The wiring both in and out of the inverter must also be protected
from short circuits and overloads by a fuse or circuit breaker. Typically, a 60 amp circuit breaker will
protect #6 AWG wiring. Consult your local code for more information and for other wire sizes.
