electrical code requirements that separately derived AC sources (such as
inverters and generators) have their neutral tied to ground in the same way that
the neutral conductor from the utility line is tied to ground at AC breaker panel.
Caution!
The negative DC input of the power inverter is connected to the chassis.
Do not install the power inverter in a positive ground DC system. A
positive ground DC system has the positive terminal of the battery
connected to the chassis of the vehicle or to the grounding point.
Warning!
Do not operate the power inverter without connecting it to ground.
Electrical shock hazard may result.
5.0 Operation
To operate the power inverter, turn it on using the ON/OFF switch on the front
panel. The power inverter is now ready to deliver AC power to your loads. If you
are operating several loads from the power inverter, turn them on separately after
the inverter has been turned on. This will ensure that the power inverter does not
have to deliver the starting-currents for all the loads at once.
5.1 Operating On/Off Switch
The ON/OFF switch turns the control circuit in the power inverter ON and OFF. It
does not disconnect power from the power inverter. When the switch is in the
OFF position, the power inverter draws no current from the battery. When the
switch is in the ON position but with no load, the power inverter draws less than
1.65 A / normal, 0.07 A / saving mode (12 V version) from the battery.
5.2 Battery voltage indicator
The battery voltage bar graph on the SW1500 indicates the voltage at the input
terminals of the power inverter. At low input current, this voltage is very close to
the battery voltage. At high input current, this voltage will be lower than the
battery voltage because of the voltage drop across the cable and connections.
Ideally, the voltage should remain in the green area of the bar graph. If the
voltage goes into the red area at the top and bottom of the graph, inverter may
shut-down. The SW600 has a LED that changes colour from green to red as
battery voltage
decreases.
5.3 Load watt indicator
The AC load watt bar graph on the SW1500 indicates the power drawn from the
power inverter. It will indicate watt by loads. For long-term operation, the watt
should be in the green and orange area of the bar graph. The SW600 load level
indicator should be green for long-term operation. Short-term operation is
possible with the load indicator in the red area. If the load rises dangerous levels,
the inverter will protect itself. The SW600 has a LED that goes from green to red
at peak wattage.
