Ensure the inverter switch is in the off position, then connect the DC input wiring
from a suitable deep-cycle lead-acid battery to the inverter back panel input bus
bars using appropriately rated high current wire (as required by your local
Authority Having Jurisdiction) with an in line Branch Rated over current protection
fuse or circuit breaker in the non-grounded battery lead (Maximum rating as
shown in Table 1). Terminate the wires with the appropriate size of crimp-on ring
tongues
to fit the 5/16”
(7.9mm) input bus bar mounting holes. Connect the
battery wiring with the input fuse removed, or with the battery circuit breaker
switched to the
“Off” position.
Figure 4: Back Panel Connections
Connect the AC loads to be powered by the inverter to the AC OUT wire clamp
connector (Line, Neutral and Ground) located on the back panel (see Figure 4)
using suitably rated wire. Alternatively, cord connected devices may be directly
plugged in to the AC outlets located on the inverter front panel.
Connect an external AC power source (grid power or AC generator) to the AC IN
wire clamp connector on the back panel of the inverter using suitably rated wire.
This must be done before turning on the inverter as the neutral line is NOT
internally bonded to the chassis. Ensure the external AC power source is switched
off before making any connections. Branch rated overcurrent protection (fuse or
