Using the PORTAWATTZ 400
Refer to Figure 1 in Section 3 for location of the items identified
below.
8.1 Indicators and Controls
·
Two AC outlets are provided on one end of the PORTAWATTZ
400. Any combination of 115-Volt AC products with a total power
consumption of 400 Watts or less may be plugged in.
·
The ON/OFF switch enables output AC power at the AC outlets
when switched ON. It also acts as a manual reset for overload,
low / high battery voltage and over temperature fault conditions.
Reset occurs by switching OFF for 5 seconds, then back ON again.
·
The green POWER light indicates AC power is present at the two
AC outlets and the PORTAWATTZ 400 is operating normally.
·
The red FAULT light indicates inverter shutdown caused by low
or high voltage, overload or excessive temperature.
8.2 Inverter Operation
1. When properly connected to a 12-Volt battery, turning the ON/
OFF switch ON, will illuminate the green POWER light, activate
the cooling fan, and deliver AC power to the two outlets.
2. As the battery charge is used up, battery voltage begins to fall.
When the PORTAWATTZ 400 senses that the voltage at its DC
input has dropped to 10.7 Volts, an audible alarm sounds. This
allows time for computers or other sensitive devices to be shut
down.
3. If the audible alarm is ignored, the PORTAWATTZ 400 will
automatically shut down when the battery voltage drops to 10.0
Volts. This prevents battery damage from excessive discharge.
After auto shut down, the green POWER light is switched off,
and the red FAULT light illuminates.
IMPORTANT:
Vehicle batteries are designed to provide brief
periods of very high current needed for engine starting. They
are not intended for constant deep discharge. Regularly
operating the PORTAWATTZ 400 from a vehicle battery until
the low voltage alarm sounds will shorten the life of the battery.
4. If an AC product rated higher than 400 Watts (or which draws
excessive surge power) is connected, the PORTAWATTZ 400 will
shut down. The green POWER light will turn off and the red
FAULT light will turn on.
