INSTALLATION: HARDWIRED UNITS
CAUTION! Battery input cables must be connected to the battery with proper polarity
as instructed or damage to the inverter may occur.
1. The unit should be OFF before installation begins. Make sure the ON-OFF/RESET Inverter Switch is in
the OFF-RESET position (button NOT pushed in).
2. Select a location for the unit that is: a) close to the battery–within 6 ft. using #2 gauge wire, b) protected
from the weather, and c) well ventilated.
3. Route the negative and positive DC input cables from the inverter/charger to the battery. If required,
protect cables where they come into contact with hard or sharp edges.
4. Install an inline fuse (Bussman ANN 125 for 12 volt applications or ANN 80 for 24 volt applications) in
the positive (RED) DC input cable between the battery and inverter (within 18 ” of the battery).
5. Connect the negative (BLACK) DC input cable to the battery negative (-) terminal. Connect the positive
(RED) DC input cable to the battery positive (+) terminal.
6. Select the proper battery type (GEL or flooded lead acid), load demand option, and charge rate using
recessed switch on front panel.
7. Connect the AC input of field wiring compartment to AC source using properly sized wire and wire nuts
(10AWG recommended).
8. Wire AC output to appropriate branch circuits. All branch circuits of a recreational vehicle which are
powered by this inverter must use one of the following GFCI: Hubbell GF5252GYA, GFRST15W**, Pass
and Seymour 1591-GRY, Pass and Seymour 2091-SGRY, GE THQL-1115GF or Leviton 6490-I.
9. Verify all connections are tight and secure for maximum performance. Installation is now complete.
**Note: If GFCI trips and the inverter is in load demand mode the GFCI may not reset until you toggle inverter off and back on and
then you will have 5 seconds to reset GFCI before unit goes back into load demand again or you can disable load demand via
dipswitch, if available.
