WHISTLER PP500AC
The fuse compartments are easily accessed at the back of the unit
underneath the "lift up" covers. (See "Rear View" Illustration, Page 3).
Note:
•
Do not install a fuse with a rating higher than 35 amps. Doing so
may damage the inverter.
•
Make certain to correct the source of the overload which caused the
blown fuse before turning the WHISTLER 500 back ON (I).
The Power Source.
When the engine is off, most automobile and marine batteries will
provide an ample power supply to the inverter for 30 to 60 minutes.
The actual length of time is a function of several variables including the
age and condition of the battery and the power demand being placed
on it by the equipment being operated with the inverter.
If you are using the inverter while the engine is off, we recommend you
start the engine every hour and let it run for approximately 10 minutes
to recharge the battery. We also recommend that the device plugged
into the inverter be turned off before turning over the engine.
Although it is not necessary to disconnect the WHISTLER 500 when
turning over the engine, the inverter may momentarily cease operation
as the battery voltage decreases. When the WHISTLER 500 is not
supplying power, it draws very low amperage (< 0.6 A) from the battery
and may be left connected to the battery for up to three hours. How-
ever, we recommend the inverter always be disconnected when not in
use.
Automatic Shut Down Safety Features.
The LED Indicator light (See "Front View" Illustration, Page 3) will turn
from GREEN to RED and the WHISTLER 500 will turn itself off automati-
cally when:
1. The power input from the battery drops to 10.5 volts. (When the power
input drops to 11 volts, an alarm will sound for an extended period);
2. The power output from the battery exceeds 15 volts;
3. The continuous draw of the equipment or appliance being operated
exceeds 500 watts.
4. The circuit temperature exceeds standard design parameters for safe
operation.
