2-6. Marking DC Wiring Connections:
Follow this procedure to connect the battery cables to the DC input terminals on the
PSW2KVA/E 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.
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.
Increasing your DC cable size will help improve the situation.
Our company recommends the following cables for optimum inverter performance
