Important: Follow the electrical and/or building code when you connect the unit to any AC
source.
Inverter AC Output Panel (wire size and breaker size):
• #10 AWG wire is required for all AC Output connections based on the full 30A pass-through
rating between the unit and the AC Inverter AC Panel.
• To meet CSA, UL and electrical code requirements and to protect system wiring, the AC input
line must be provided with an overcurrent protection device for which a maximum 30A branch
circuit breaker is required to connect each AC Output Line to the unit’s AC Output. If an AC
Output wire of smaller than #10 AWG is used, then the overcurrent protection device will have
to be smaller. Follow the electrical and or building code to choose your protection device rating.
Installing the Inverter-Charger System
WARNING : Electrical Shock Hazard
The unit ‘On/Off’ switch does not disconnect the DC power from the battery. Use the DC
Disconnect Switch or disconnect the DC input cable connection to disconnect the DC
power from the battery before working on any circuits connected to the unit. Use the AC
circuit breaker to disconnect any AC power to the unit before servicing. Failure to follow
these instructions can result in death or serious injury.
Installation:
• Choose an appropriate mounting location. The unit should be installed away from the battery
in a separate well ventilated compartment. Do not install the unit in any compartment
containing flammable gases or liquids like gasoline or in the battery compartment where they
may be explosive hydrogen gas from the batteries present.
• The length and size of the DC cables will affect unit performance.
• For indoor use, the unit can be mounted in any direction except with the fan panel (panel with
fan opening) facing upwards or downwards.
• The location to install the unit has to have a normal air temperature between 0°C – 60°C
(32°F-140°F). The cooler the better, or overheating may result.
• Use the mounting template below to mark the positions of the mounting screws.
• Drill the 4 mounting holes and place the Inverter-Charger in position and fasten the unit to the
mounting surface.
AC Input Wire Connection:
DANGER: Make sure all the AC wiring being connected to the unit is physically
disconnected or by opening the circuit breaker from the electrical sources. All wiring
must be done in accordance with local and national electrical wiring codes.
CAUTION: The terminal block is split into AC Input and AC Output sections. Damage will
occur to unit if it is wired incorrectly.
•
The AC and DC wire cannot be mixed together in the same conduit.
• The AC input and AC Output wire should be separated out through the two AC knockouts
located at the bottom of the unit.
• Remove AC compartment cover by unscrewing the four screws located on the four corners of
the AC compartment cover.
• There are two ground bus locations inside the AC Wiring Compartment. The ground bus
