The red terminal is positive (+) and black terminal is negative (-).
Insert the cables into the terminals and tighten relative nut to clamp the wires securely.
WARNING!
You may observe a spark when you make this connection since
current may flow to charge capacitors in the power inverter.
Do not make this connection in the presence of flammable fumes.
Explosion or fire may result.
WARNING!
Make sure all the DC connections are tight (torque to 9-10 ft-lbs,
11.7-13Nm). Loose connections will overheat and could result in
a potential hazard.
2-3-3 Safe
–
Do not install in a battery compartment or other areas where flammable
fumes may exist, such as fuel storage areas or engine compartments.
2-3-4 Ventilated
–
Allow at least one inch of clearance around the inverter for air flow. Ensure
the ventilation openings on the rear and bottom of the unit are not obstructed.
2-3-5 Dust-free

Do not install the Inverter in a dusty environments where are dust, wood
particles or other filings/shavings. The dust can be pulled into the unit when the cooling
fan is operating.
2-3-6 Close to batteries
–
Avoid excessive cable lengths but do not install the Inverter in the
same compartment as batteries.
Use the recommended wire lengths and sizes (Ref. point 2-6).
Also do not mount the Inverter where it will be exposed to the gases produced by the
battery.
These gases are very corrosive and prolonged exposure will damage the Inverter.
