SAFETY

A few common-sense precautions should be observed:

1.The inverter delivers 115 volts AC. This is the same kind of electricity as in the wall sockets of most homes and offices. 115 volts AC is potentially lethal and must be treated with respect.

2.The inverter is polarity sensitive and will be damaged if connected to the battery incorrectly. If there is any doubt, consult an electrician. (See Installation).

3.A safety hazard will result if inadequate wiring is used to make connection to the inverter. (See Installation).

4.The inverter is intended to deliver stand-alone AC power. Its output cannot be safely connected to utility power, another inverter, a generator, or any other power source. Where other power sources are available in the same system, isolating relays should be used to prevent connection of the inverterÕs output to those other sources of AC.

5.In case of malfunction, immediately turn the power switch OFF and disconnect the inverter from the battery.

6.DO NOT STICK ANYTHING INSIDE THE CASE. The high voltage inside can cause severe injury, even death.

7.KEEP THIS UNIT AWAY FROM CONTACT WITH WATER OR OTHER LIQUIDS.

8.DO NOT OPERATE THIS UNIT, or any electrical device, when you, the device or any surfaces that might touch a power source are WET. Many fluids can conduct electricity, causing severe injury, even death.

9.DO NOT OPEN THE CASE. This will void your warranty.

INSTALLATION

When working on the installation, be sure that the inverter power switch is in the OFF position. Note that this is only a control switch which tells the inverter whether or not to run. Even though it may be OFF, the battery will still be connected directly to the inverterÕs input terminals, so they will always be live. Treat them accordingly.

Please get the polarity right. If you get it wrong, you will damage the inverter and void the warranty. It does happen, despite this warning. So please double check before you make that last connection. The positive (+) terminal on the battery should connect to the positive

(+)terminal on the inverter, and the negative (Ð) terminal on the battery should connect to the negative (Ð) terminal on the inverter.

SUGGESTION: Before making the last connection, brush the cable lightly against the terminal. There should be no spark, or at most a very slight one. Heavy sparking indicates a problem.

The inverter may be mounted in any position on any flat surface: wall, ceiling or floor. It should be bolted or screwed down using a #6 screw in each of the four mounting holes. In choosing a location, look for a dry, cool, dust-free, well ventilated spot as close to the battery as possible, but clear of battery acid and fumes. Under the hood of a vehicle is a harsh environment which should be avoided.

The battery cables are the key to a successful installation. They must be at least AWG (American Wire Gauge) #4 and should be as heavy and as short as practical. To be extremely conservative just use #2 gauge wire which is as large as the inverter terminal will accept. Otherwise, the minimum acceptable sizes are shown below. The wire and the appropriate battery terminals are usually available from auto supply stores. If you cannot find the right wire there, try an electrical distributor or a welding supply house.
