Operating Environment
Do not locate inverters in an area, room or compartment where explosives or flammable fumes might be present, such as engine rooms, engine compartments, and boats or small, unvented battery compartments.
To avoid possible dangerous conditions, the inverters must be located where:
1.The unit is kept dry;
2.Air temperature is between 30°F
3.At least three inches of clearance from other objects is maintained for cooling airflow;
4.The unit is not exposed to direct heat, sunlight or to explosive or flammable fumes; and
5.The unit is as close to the DC power source as possible.
Never connect the chassis ground wire from the inverter to the DC negative input.
•CHECK to ensure that the combined loads of the appliances being powered by the inverter DO NOT continuously exceed the inverter’s wattage rating.
•NEVER place items on or over the inverter during operation.
MAXX SST™ inverters generate heat during operation and must be placed where cool air can circulate to the internal fan, and hot air can be removed.
Installation Procedures
When wiring the inverter to a 12 volt DC power source, ensure that polarity is correct. Reversed polarity will blow a fuse and may cause permanent damage to the inverter. Review ”Back View Diagram” on page 4, if necessary, to identify the location of the DC terminals.
Note: The manufacturer’s warranty does NOT cover damage due to reversed polarity.
Temporary Installation
For Temporary Installation, only use a dual cable set (2 Red - Positive; 2 Black - Negative) with 3 feet long cables each using #2AWG wire terminated with a ring terminal attached at the battery (power source) end and a Special Crimp Connector attached at the inverter end. The Special Crimp Connectors are designed for proper connection to the 12 volt input power terminals on the inverter; connection using any other method is not acceptable.
1.Check to be sure the inverter’s ON/OFF Power Switch is in the OFF position and that no flammable fumes are present.
2.Locate the Positive (+, POS) and Negative
3.Locate the Positive (Red, +) and Negative (Black,
4.Connect the Special Crimp Connectors of the Positive (Red, +) cables to the Positive (Red, +) terminals on the inverter and tighten the set screws against the flat side of the connectors.
5.Connect the ring terminals of the Positive (Red, +) cables to the Positive (+, POS) terminal on the 12 Volt DC battery (or other 12VDC power source).
6.Connect the Special Crimp Connectors of the Negative (Black,
7.Connect the ring terminals of the Negative (Black,
WARNING: If persistent, severe arcing occurs between the cable and battery terminals, immediately cease attempting to make the connection and correct the cause of the problem before continuing.
8.Ensure that all of the electrical connections have been tightened.
9.Set the inverter’s ON/OFF Power Switch to the ON position and verify the Green Power LED Indicator illuminates and the Red Fault LED Indicator does not illuminate.
10.As a test, plug in a lamp with a 60 or 100 Watt light bulb into one of the inverter’s 120 Volt AC Outlets and switch the lamp ON. If the lamp lights normally, the inverter is functioning properly and use of the inverter with other appliances can continue. If the lamp does not light, or does not operate normally:
A.Refer to the “Fault Protection and Troubleshooting Guide” of this Instruction Manual for suggested solutions.
B.If conducting step A does not find and correct the problem, refer to the “Service Information” section of this Instruction Manual for assistance.
