2-6. Marking DC Wiring Connections:
Follow this procedure to connect the battery cables to the DC input terminals on the
Inverter. 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
inverter 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
inverter to the batteries.
The longer and narrower these cables, the greater the voltage drop.
Increasing your DC cable size will help improve the situation.
Our company recommends the following cables for optimum inverter performance (apply
both 120V and 230V versions)
Model No
YK-PSW245KVA
YK-PSW245KVAE
YK-PSW485KVA
YK-PSW485KVE
YK-PSW1105KVA
YK-PSW1105KVAE
YK-PSW2205KVA
YK-PSW2205KVAE
Also, use only high quality copper wiring and keep cable length short from 3-6 feet.

Inverter Operation:
To operate the power inverter, turn it on using the ON/OFF switch on the front panel. The
power inverter is now ready to deliver AC power to your loads.
If you are operating several loads from the power inverter, turn them on separately after the
inverter has been turned on.
This will ensure that the power inverter does not have to deliver the starting currents for all
the loads at once.

WARNING!
The installation of a fuse must be on positive cable.
Failure to place a fuse on "+ "cables running between the
inverter and battery may cause damage to the inverter and will
void warranty.
