Preparing for Installation
Typical Wiring block diagram of the Power Inverter:
12V Battery Bank:
•
The use of a deep cycle battery is highly recommended for power inverter application
•
For battery size, you need to identify what you wish to operate, and for how long. It is
recommended that you purchase as much battery capacity as possible. See more on Battery
Run Time in Section 4.
DC Fuse or Circuit Breaker:
•
DC-rated fuse or DC-rated circuit breaker connected along the DC positive line is required.
Select a fuse or circuit breaker with a minimum of 450 Adc
•
Based on the size of your 12V Battery Bank, determine the overall short circuit current rating of
the battery bank from the battery manufacturer. The fuse or circuit breaker chosen has to be
able to withstand the short circuit current that may be generated by the battery bank
DC Disconnect Switch:
•
Select a DC Disconnect Switch with the same or higher rating of the selected fuse or circuit
breaker.
•
The DC Disconnect Switch is used to disconnect the DC power between the unit and the battery
bank during service, maintenance or trouble shooting.
DC Input Cable Size:
•
Use of isolated multi-strand low resistance wire is required for all the DC connections between
the unit and the battery bank.
•
Use minimum #4/0 AWG wire with maximum cable length of 5 feet.
Important: Use of smaller gauge cable or longer cable length may cause the inverter to shutdown
under heavy load and may also melt the cable insulation and catch fire and can result in death or
serious injury.
Grounding Cable Size:
Important: The unit is grounded through the ground stud located near the DC Input terminal and
the chassis of the unit has to be grounded properly before use.
•
For Marine application, the DC grounding cable size may be one size smaller than the minimum
size conductor required for the DC current-carrying conductors and the conductor is no smaller
than #10AWG.
•
For Recreational Vehicle or Caravan application, the unit has to be grounded to the vehicle
chassis with a minimum #8 AWG copper conductor.
Installing the Inverter 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 cables to disconnect the DC power from the
battery before working on any circuits connected to the unit. Failure to follow these
instructions can result in death or serious injury.
Installation:
•
Choose an appropriate mounting location.
•
For indoor use, the unit can be mounted in any direction except with the DC Input panel facing
downwards.
•
Use the mounting template below to mark the positions of the mounting screws.
