Preparing for Installation
Typical Wiring block diagram of the Power Inverter:
12V Battery Bank:
 The use of 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. NATURE
POWER recommends that you purchase as much battery capacity as possible. See more on
Battery Run time and Load in Section 4.
Fuse or Circuit Breaker:
 DC-rated fuse or DC-rated circuit breaker connected along the DC positive line is required.
 For 32326, select a fuse or circuit breaker with a minimum of 300 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
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 and Grounding Cable:
 Use of low resistance wire is required for all the DC connections between the unit and the
battery bank.
 For 32326, use minimum #2/0 AWG wire with maximum cable length of 5 feet.
Important: The unit is grounded through the ground stud of the unit located near the DC Input
terminal.
 For the grounding cable connected between the unit’s chassis and the earth ground, use a
matching cable size as used on the DC Input Cable section.
AC Input Source and Branch Breaker:
 Standard AC Input wire is required for all the AC connections between the AC source & the AC
Input port, and the AC Output ports to load.
 A 30A branch circuit breaker is required to connect between AC Input source and unit’s AC Input
port.
Important: Follow the electrical and or building code when you connect the unit to any AC source.
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 cables connection 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.
