3. USE AS A 12 VOLT DC PORTABLE POWER SUPPLY
WARNING: NEVER INSERT A CIGARETTE LIGHTER IN POWER CITY’S ACCESSORY SOCKET.
1.Lift up the cover of one of the12 volt DC Accessory Sockets.
2.Insert the 12 VOLT DC plug from the appliance into the Accessory Socket.
3.Switch on the appliance, as usual.
4.Periodically press the Battery Status Pushbutton to check battery status.
5.When the Charge Status goes to one red LED, recharge the Main Unit battery.
CAUTION: DO NOT USE POWER CITY TO OPERATE DC APPLIANCES THAT DRAW MORE
THAN 23 AMPS.
4. POWER INVERTER
The Power Inverter is an electronic device that converts low voltage DC (direct current) from the
battery or other power source to standard 110 volt 60 Hz AC (alternating current) household
power. Safety features include an audible low battery alarm and automatic shutdown to
prevent damage to your Power City internal battery. See Figure 4.
FIGURE 4
4.1 INVERTER OPERATION
Removing the cover that protects the AC receptacle on the inverter can access the inverter.
NOTE: On this end of the inverter are: the AC receptacle, the On/Off Switch, a green LED and
a red LED. The green LED, when lit, indicates power is applied to the inverter and it is
operating properly. The red LED, when lit, indicates that something caused the inverter to
shut down. The green LED will not be lit under shutdown conditions. Inverter shutdown is
caused by: under- or over-voltage, overheat or overload. If the inverter shuts down, first
check the Main Unit battery (use Battery Status Push-button and Display) to see if the main
battery is discharged, Recharge the battery as soon as possible. If another condition caused
the shutdown, investigate the appliance for excessive wattage or a connection between
neutral and ground (explained later). If the inverter feels very warm let it cool before
restarting it. Restart is accomplished by turning the Inverter Switch Off, then On.
Operation is simple:
• Remove Inverter's Receptacle Cover
• Plug the appliance's 110 volt plug into the Standard AC receptacle on the inverter.
• Turn On the inverter power switch.
• Turn On the appliance and operate it as usual.
• After use, turn off the power inverter's On/Off Switch
The Inverter can also be used away from the Main Unit by removing it from it's mounting on the
Main Unit and powering it from the Inverter Power Cable. Located in the Cable Storage
Compartment. See Figure 3.
