HARD-WIRED OUTPUT

If it is desired to permanently connect the inverterÕs output to a string of outlets or to a load, the remote connector should be used. The three right-hand terminals correspond to (3) White: neutral;

(4)Black: hot; and (5) Green: ground or chassis. Any three-wire electrical cable will have these colors (although the ground wire may be bare copper instead of green), and the wires should be connected to their corresponding terminals. For a wire run of 50 feet or less, AWG #14 can be used. If itÕs longer, use AWG #12.

CAUTION: When making a permanent installation, make sure these same lines being fed by the inverter will never be fed by shore power, a generator, another inverter or any other source of AC; once again, that would cause damage and void the warranty. If you wish to use another source of AC on the same lines, it is necessary to disconnect the inverter first. To do this automatically, install a DPDT (double-pole, double-throw) relay in the White and Black lines.

OPERATION

Using your inverter is quite simple. Just turn the switch ON, and observe that the AC light comes on, indicating there is

115 volt AC power at the output. Any appliance connected to the inverter will operate, if it is within the inverterÕs power capability. Should you wish to connect more than one appliance to the inverter, a multi-tap extension cord may be used. It should be rated at a minimum of 12 amps.

Please note that the fan will run only when the inverter is loaded beyond 120 watts.

When operated at full load for extended periods it is normal for the inverter to be HOT to the touch.

The output is factory pre-set to 115 volts AC at 60 Hertz. The wave- form, a Òmodified sinewaveÓ, has been found satisfactory for running virtually all loads. The output voltage can only be measured accu- rately with a Òtrue RMSÓ voltmeter. Because of the special waveform, all other voltmeters, analog or digital, will read 10 to 20 volts low.

Low Battery

If the voltage at the input terminals of the inverter drops below 10.3 volts, the LOW BATTERY ALARM will emit a high-pitched warning tone, and the inverter will continue to operate. The tone will stop if the voltage is raised back above 12.0 volts.

If the battery voltage continues downward, the tone stays on and the inverter keeps running until the voltage drops below 10.0 volts. At this point the inverter locks itself off to protect your battery, but the warning tone stays on.

To reset:

Manually: Turn the power switch OFF for one second and then back ON.

Automatically: Recharge the battery above 13.0 volts.
