INSTALLATION
9.Do not backfeed the AC output of the in- verter with incoming AC power. A backfeed occurs when AC power from shorepower or generator is connected to the output of the inverter. This will damage the inverter and void the warranty. Remember that incoming AC must be fed only to the AC input and never the AC output. Always check for AC voltage before connecting wires to the AC output. Do NOT turn the inverter ON until all AC connections have been made. Backfeeding the inverter voids the warranty.
covered in recommended heat shrink tubing. Carefully follow the manufacturer’s directions to meet all requirements.
12.If installing in a system which includes an existing battery charger or AC to DC converter, make sure these do not operate from the inverter output AC power. This sets up a power loop which, due to inefficiencies, will quickly drain the batteries.
WARNING
Do not connect incoming AC from any source to the AC output of the inverter. This is known as backfeeding, and will damage the unit and void the warranty.
10.Do not connect the AC input to the AC output. This would be equivalent to plugging the battery charger into the inverter. This could occur if the unit’s AC output is connected to the entire leg of a circuit breaker panel, then a circuit breaker on that leg is used to feed the battery charger input. This will cause the unit to oscillate ON and OFF when the unit is in inverter mode.
11.Always use proper wire and connectors. The proper battery cable size is critical. Consult ABYC, UL, NEC or your marine electrician for recommended battery cable size. Considerable amperage flows in the DC circuit. Use recommended cable termi- nated on each end with recommended ring terminal connectors. Be sure the connectors are attached to the cable using a method approved by the connector manufacturer. After the crimp is made, the barrel of the terminal and the first inch of the cable needs to be
