CAUTION:
The PROwatt 250 must be connected only to bat-
teries with a nominal output voltage of 12 volts (24 volts for
PROwatt 250/24V). The PROwatt 250 will not operate from a
6 volt battery (12 volt for PROwatt 250/24V) and will be dam-
aged if connected to a voltage source above 16 volts (32 volts
for PROwatt 250/24V).
3.2 Connecting to power source
The PROwatt 250 is equipped with a cigarette lighter plug for
connection to the power source. The tip of the plug is positive
and the side contact is negative. Connect the plug to the ciga-
rette lighter socket in a vehicle or to the cigarette lighter socket
on a battery pack.
CAUTION: CONNECT THE 12V PROwatt 250
DIRECTLY TO POWER SOURCE WHEN OPERATING
ABOVE 150 WATTS
The cigarette lighter plug is suitable for operating the 12V in-
verter at power outputs of up to 150 watts. If the PROwatt
250/12V power inverter is to be used for extended periods at
power levels above 150 watts, direct connection to the power
source is recommended. Removal of the lighter plug is not nec-
essary for the PROwatt 250/24V.
To make a direct connection, follow these steps:
1) Cut the cigarette lighter plug from the PROwatt 250 cord.
One conductor on the PROwatt cord is marked with a red or
white stripe. This is the positive conductor.
