4.8 System ON/OFF Switch
Use this rocker switch to turn the system ON and OFF and to reset the system. The System ON/OFF Switch
does not interrupt Aux AC input power or DC input power to the system.
4.9 Remote Signal Contacts
Three sets of contacts provide signals (continuity) for Remote Inverter ON/OFF indication, Remote Low Battery
Warning indication and Gen Start control. Contacts are rated 2 amps for 12 or 24 volt, Class 2 circuits. Wiring
connections are made through a 6 conductor plug-in terminal block. Screw pressure-clamp terminals accept up
to 14 gauge wire.
5 INSTALLATION
Unpacking the Inverter
Inspect the shipping container and equipment for loose or damaged parts. If any damage is found, immediately
notify the freight carrier.
5.1 Basic Guidelines
The wiring of your inverter installation should conform to the National Electric Code (NEC) and any other state
or local codes in effect at the time of installation. These codes have been written for your protection and their
requirements should be followed.
Mounting
Locate a secure, dry, flat horizontal or vertical surface large enough to mount the inverter. The location should
be as close to the battery as possible without being in the same compartment and should provide adequate
ventilation to maintain room temperature while the inverter is operating. The location must allow unobstructed
cooling air flow at sides and bottom of the unit, and the location must be free from road spray, dripping water or
other moisture contamination. A recommended minimum clearance of 4 inches (102 mm) should be
maintained on all sides of the unit.
WARNING:
Risk of fire or explosion. The inverter must not be mounted in fuel storage areas, battery
compartments, or other areas hazardous locations requiring ignition protection.
NOTE
The wiring of your inverter installation should conform to the National Electric Code (NEC) and any other state
or local codes in effect at the time of installation. Article 551 of the NEC requires any DC cable from a battery,
which measures longer than 18 inches along its length, be protected by a fuse. Other codes may require each
ungrounded output conductor from a storage battery, other than to the engine cranking motor, to have a
manually reset trip-free circuit breaker or fuse within 72 inches of the battery as measured along the conductor.
5.2 DC Wiring
Preliminary Considerations
1.
BE AWARE
that, as a large number of capacitors become charged upon completion of the DC circuit,
THERE WILL BE A LARGE SPARK
when the last battery connection is made. The spark is normal and will
occur every time the batteries are connected.
2. The DC cables should be as short as possible. It is electrically more efficient to run the lower current AC
wiring longer distances than the DC cables. (See DC Cable Sizing Chart for proper size.)
3. Route the DC positive and negative cables as close together as possible, and use cable ties to keep them
together. This reduces some electromagnetic radiation that could interfere with some sensitive electronics.
3. On vehicle installations do not use the vehicle chassis as the DC negative conductor. Use a cable the same
size as the DC positive to go directly from the inverter to the battery negative.
4. Route the AC and DC power wiring separately, and with as much physical separation as possible, from low
voltage wiring such as audio and video signal wires.
