Prior to Main Input Power Connections:
Make connections A through D prior to hook up to the vehicular power source as shown in Figure
#2. This ensures that there is no sparking from the source of power and allows a reprieve in case there is
a hook up error. (User should carefully review connections as such an error would have to be detected
prior to energizing the unit).

A) Connect input +(22-60)V line to position #1 of TBB.
B) Connect input ground to position #2 of TBB.
C) Connect output 13.6 V ground to position #3 of TBB.
D) Connect output +13.6V line to position #4 of TBB
Note: The two ground positions are in the center of the terminal block adjacent to each other.
Prior to energizing, installer should:
1) Ensure that hook up in steps A through D is correct.
2) Select the suitable method of converter activation.
2.3 Methods of Converter Activation
A) Connect terminal #1 to terminal #2 on terminal block TBA. The 382 is so configured
when shipped from the factory. This configuration allows for converter activation by
either turning the source power ON and OFF.
B) Terminal #1 can be connected to terminal #2 through a remote ON/OFF switch or relay
thereby activating the converter.
2.4 Power Limiting & Overload Protection
The 382 begins to electronically limit power once 450W output is exceeded.
In the event that the converter is misused e.g. its input is connected in reverse polarity, the circuit
breaker on the rear panel provides secondary protection. IT IS ADVISABLE TO TRY TO AVOID
REVERSE POLARITY AS IT MAY RESULT IN PERMANENT DAMAGE TO THE UNIT.
