Connecting the Inverter
This inverter has two DC cable connections, one positive and one negative. The order of steps
in the following procedure minimizes the danger of sparking near the battery bank.
1. Prepare all cable set ends with ring terminals at the battery ends.
2. Install one fuse holder with fuse in the Positive (+) cable close to the battery bank end.
3. Make sure the inverter is OFF.
4. Ensure all appliance cords or extension cords are disconnected from the inverter.
5. Connect an appropriate stranded insulated wire to the enclosure ground terminal and
connect the free end of the wire to the vehicle’s chassis or any other ground point.
6. Connect the unfused cable to the Negative (-) terminal of the battery bank.
7. Connect the Negative cable to the Inverter’s Negative (-) terminal.
8. Insulate the end of cable to be connected to the Positive (+) inverter terminal.
9. Connect the fused cable to the battery bank Positive (+) terminal.
10. Connect the Positive cable end to the Positive (+) inverter terminal.
NOTE: Sparking is normal for the first connection.
Make sure you have good secure connections – Do not over-tighten.
Operation
1. Turn On the inverter.
2. Turn OFF the inverter.
3. When you have confirmed that the appliance to be operated is turned off, plug an ap-
pliance cord into one of the two 110 V AC Outlets on the front panel of the inverter.
4. Turn ON the inverter.
5. Turn the appliance on.
6. Plug in additional appliances and turn them on.
Note:
The audible alarm may make a momentary “chirp” when the inverter is turned OFF. This same
alarm may also sound when the inverter is being connected to or disconnected from the 12
volt battery bank.
Television and Audio Suggestions
Although all Enerwatt inverters are shielded and filtered to minimize signal interference, some
interference with your television picture may be unavoidable, especially in weak signal areas.
However, here are some suggestions that may improve reception:
1. First, make sure that the television antenna produces a clear signal under normal operating
conditions. Also, ensure that the antenna cable is properly shielded and of good quality.
2. Change the positions of the inverter, antenna cables and TV power cord.
3. Isolate the TV, its power cord and antenna cables from the 12 volt power source by run-
ning an extension cord from the inverter to the television set.
4. Coil the television power cord and the input cables running from the 12 volt power
source to the inverter.
5. Attach a “Ferrite Data Line Filter” to the television power cord. More than one filter may
be required. These filters are available at most electronic supply stores.
Note:
Some inexpensive audio systems may produce a slight “buzzing” sound when operated with
the inverter. The only solution to this problem is to use a sound system with better power
supply filtering.
