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)
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 pushbutton 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)
