Making Dc Wiring Connections - Helios RM-PSW5KVA Series Instruction Manual

230V models: There is no connection made inside the YK-PSW5KVA/E Inverter
from either the line or neutral conductor to the safety ground.
Ground Fault Circuit Interrupters (GFCI'S):
Installations in Recreational Vehicles (for North American approvals) will require GFCI
protection of all branch circuit connected to the AC output of the hardwire terminal equipped
inverter. In addition, electrical codes require GFCI protection of certain receptacles in
residential installations. While the pure sine wave output of the inverter is equivalent to the
waveform provided by utilities, compliance with UL standards requires us to test and
recommend specific GFCI. Our company has tested the following GFCI-protected 20A
receptacles and found that they functioned properly when connected to the output of the
inverter.
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.
WARNING!
Do not operate the power inverter without connecting it to
Ground.
Electrical shock hazard may result.
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.
