Making DC Wiring Connections
Follow this procedure to connect the battery cables to the DC input terminals on the unit.
Your cables should be as short as possible (ideally, less than 10 feet / 3 meters) and
large enough to handle the required current in accordance with the electrical codes or
regulations applicable to your installation.
Cables that are not an adequate gauge (too narrow) or are too long will cause decreased
unit performance such as poor surge capability and frequent low input voltage warnings
and shutdowns. These low input voltage warnings are due to DC voltage drop across the
cables from the unit to the batteries.
The longer and narrower these cables, the greater the voltage drop.
WARNING!
The installation of a fuse must be on positive cable.
Failure to place a fuse on

cables running between the
unit and battery may cause damage to the unit and will void
warranty.
Increasing your DC cable size will help improve the situation.
Our company recommends the following cables for optimum unit performance (apply both
120V and 230V versions.

Also, use only high quality copper wiring and keep cable length short from 3-6 feet.
2-7 Operation
To operate the unit, turn it on using the ON/OFF switch on the front panel.
The unit is now ready to deliver AC power to your loads.
If you are operating several loads from the unit, turn them on separately after the unit has
been turned on.
This will ensure that the unit does not have to deliver the starting currents for all the loads
at once.
2-7-1 Controls and indicators
The ON / OFF switch turns the control circuit in the unit on and off.
The inverter operates from an input voltage range:
10.0 to 16.0 VDC for 12V models
20.0 to 32.0 VDC for 24V models
42.0 to 62.0 VDC for 48V models
