12V Battery Bank:

The use of deep cycle battery is highly recommended for power inverter application

For battery size, you need to identify how much you will be using them between charges.
KISAE do recommends 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.
 Select a fuse or circuit breaker with a minimum of 60 ADC

Based on the size of the battery bank chosen on the 12V Battery Bank above, 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 Disconnect Switch with the same or higher the rating of the selected fuse or circuit
breaker from the above.

The Disconnect Switch is used to disconnect the DC power between the power inverter and
the battery bank during service, maintenance or trouble shooting.
DC Input Cable:

Use of low resistance wire is required for all the DC connections between the inverter and the
battery bank.

Uses minimum #10 AWG wire with maximum cable length of 5 feet.
Installing the Power 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 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.
Power Inverter DC Input Connection:
CAUTION : Reverse the DC Input terminal will damage the unit and cannot be repaired.
Damage caused by reverse polarity connection is not covered by the warranty.

Connect one end of the negative DC input cable to the Power Inverter DC negative terminal
(black). Connect the other end of the negative DC input cable to the battery negative
terminal.

Make sure the Disconnect Switch is in the OFF position.

Connect one end of the positive DC input cable to the Power Inverter DC positive terminal
(red). Connect the other end of the positive DC input cable to one of the terminal of the
Disconnect Switch.

Connect a DC input cable between the other terminal of the Disconnect Switch and one side
of the terminal of the fuse holder.

Connect a DC input cable between the other terminal of the fuse holder and the battery
positive terminal.
 Install the selected fuse to the fuse holder.

Turn Disconnect Switch to ON position.
Connect unit with optional accessories (Battery clips cable or Lighter plug cable)
Using the Lighter plug cable:
CAUTION: Due to the limitations of the 12V lighter plug socket in vehicles, the unit should be
used with the DC cable with lighter plug only to supply AC power to products that
require 150W (120VAC/1.3 A) or less. If the appliance requires more than 150W,
use the optional DC cable clips for battery connection.

Attach the red ring-type connector to the positive (+) DC terminal (red) on the power
inverter and connect the black ring type connector to the negative (-) DC terminal (black)
