3.4 VENTILATION FAN
The fan is load and temperature controlled and will engage when the AC Power Consumption reaches a
certain level and when the unit gets hot. Ensure that the fan is not obstructed and is at least 25 mm (1")
away from surrounding objects.
NOTICE: Install the inverter in a well-ventilated area with reasonable clearance. Do not install the inverter
in a zero-clearance compartment or obstruct the ventilation openings. Doing so may result in the inverter
overheating and ultimately damage the inverter.
3.5 SAFETY BEFORE DC INPUT CABLE CONNECTIONS
WARNING: Risk of electrical shock. Before proceeding, carefully check that the inverter is not
connected to any batteries and that all cables are disconnected from any electrical sources. Do not
connect the output terminals of the inverter to an incoming AC source.
CAUTION: Batteries are capable of providing very large currents in the case of a short circuit. A
fuse must be installed on the positive supply cable as close as practical to the battery. Failure to do so
provides inadequate protection against re in the case of a short circuit. Only use high quality copper
cable and keep the cable length short, refer to Section 3.1 (page 14) for more information.
NOTICE:
Reverse polarity connection will blow the internal fuse and may cause permanent damage to the inverter.
The REDARC RS3 series Inverters come with a built in RCBO, which requires a good ground
connection to function as intended. Any xed wiring installations will need to be performed by a
licensed electrician.
