2.5 120 Volt AC Input 
Plug the GPC AC input cord into a 120 V 3 wire grounded source. See chart for 
maximum current draw and required input voltages. 
2.6 Reverse Polarity Fuses 
The GPC is protected against reverse polarity on the DC output. If a battery or 
the GPC is hooked up incorrectly, the fuses will blow and can be easily replaced. 
Always use the same size and style fuse that came with the converter. To 
change the fuses, use a screwdriver to loosen the screws and remove the fuses. 
Always replace the fuses with the same type and rating. After inserting the new 
fuses, tighten the screws firmly. DO NOT OVERTIGHTEN. 
3.0 Installation Guidelines 
There are no components within the GPC that, in their normal operation, produce 
arcs or sparks. However, all electronic devices have some potential for 
generating sparks in the event of failure. Therefore, never install this device in 
the same compartment with flammable items such as gasoline or batteries. 
3.1 Installation 
Disconnect the positive side of the battery before installation. Connect the 
positive (red) and negative (black) terminal lugs to battery or load. Always use 
the proper size wire based on the amperage of the converter and the battery. 
When connecting to a battery, a breaker should be installed within 18” of the 
battery, connecting the battery positive to the line side of the breaker, and the 
GPC to the load side. Connect Chassis Bonding Lug on the GPC to vehicle 
chassis or other grounding source. 
3.2 Mounting Location 
The GPC can be mounted in any position within an enclosed or interior 
compartment. Provide sufficient air space to allow unrestricted airflow in and 
around the unit. 
3.3 120 Volt AC Input 
Plug the GPC AC input cord into a 120 V 3 wire grounded source. See chart for 
maximum current draw and required input voltages.
