5. INSTALLATION and START UP
Unpacking the Inverter
1. Inspect the shipping container and equipment for loose or damaged parts. If any damage is found,
immediately notify the freight carrier.
Inverter Installation Considerations
1. Mounting: Locate a secure, dry, flat horizontal or vertical surface large enough to mount the inverter.
The location should be as close to the battery as possible, usually within six feet, but not in the same
compartment and should provide adequate ventilation while the inverter is operating. The location
must be clean, dry and free from road spray, dripping water or other moisture contamination.
2. Cooling Fan Clearance: The mounting location must allow unobstructed airflow for cooling. Allow a
minimum clearance of 1½ inches (40 mm) on the left, right and back sides of the inverter. The Cooling
Fan is a thermostatically controlled intake fan. Air is drawn into the inverter from the front and side
vents and exhausted through the fans. Obstruction of the fan intake or the exhaust vents will diminish
the inverter output capacity due to overheating.
DC Wiring Considerations
1.
A DC FUSE IS REQUIRED
to properly protect the inverter in case the battery cables are connected
backward (reverse polarity).
2.
The wiring of your inverter installation should conform to the National Electric Code (NEC) and any
other state or local codes in effect at the time of installation. These codes have been written for your
protection and their requirements should be followed. Article 551 of the NEC requires any DC cable
from a battery, which measures longer than 18 inches along its length, be protected by a fuse.
3.
BE AWARE
, as a large number of capacitors become charged upon completion of the DC circuit,
THERE WILL BE A LARGE SPARK
when the last battery connection is made. The spark is normal
and will occur every time the batteries are connected. It is advisable to make the last DC connection
at the input fuse, not at the battery, to reduce the risk of battery explosion.
4.
Route the AC output wiring and DC power wiring with as much physical separation as possible from
low voltage wiring such as audio and video signal wires.
5.
Route the DC positive and negative cables as close together as possible and use cable ties to keep
them together. This reduces electromagnetic radiation that could interfere with sensitive electronics.
6.
If passing through steel or other ferrous metal walls, the DC input cables need to pass through the
same hole to prevent causing a transformer effect. If two holes are required, cut a slot to connect the
two holes to prevent heating of the ferrous metal.
