6. DC
Wiring
IT IS ESSENTIAL that the battery bank voltage match the DC input voltage rating of the Inverter.
Damage to the
Inverter could result from improper voltage connections.
A Battery Fuse
must be installed between the batteries and the Inverter; appropriately sized Motor-Starting fuses or
similar are recommended.
Before making any connections ensure that the Inverter Power Switch is in the ‘OFF’ position.
The DC cables should be as short as possible (ideally, less than 3 metres) and large enough to handle the required DC
current in accordance with electrical codes or regulations applicable to your installation.
Cables that are not an adequate gauge ( ie too small in diameter) or are too long will cause decreased inverter
performance such as:
•
poor surge capability
•
frequent low input voltage warnings
•
shutdowns.
J. Connection and Testing
For a quick connection and performance check, please follow these guidelines:
Note:
The connection to the Negative (NEG-)
terminal of the Inverter should be the last connection made. A spark
when making this final connection is normal.
Step 1: Unpack and inspect the Power Inverter for any damage.
Step 2: Make sure the power switch in the ‘OFF’ position.
Step 3: Connect the DC Positive cable to the Positive (POS+) terminal on the battery. Next, connect the DC Positive
cable to the Positive terminal on the Inverter (via the Battery Fuse).
Make sure the connections are secure.
Before proceeding further, recheck the cable you have just connected to the Positive terminal of Inverter, and to the
Positive terminal of the battery or DC power source.
WARNING!
Do not operate the power inverter without connecting it to ground. Electrical
shock hazard may result.
WARNING!
Make sure all the DC connections/ terminations are tight (torque to 9-10
ft-lbs,11.7-13Nm). Loose connections will
overheat and could result in a
fire
hazard.
