1.0 Installation and Maintenance
1. DISCONNECT DC POWER.
Disconnect the battery

wire at the battery end before connecting this Con-
verter/Charger to any vehicle/device wiring.
2. LOCATION.
The mounting location may be on any interior (out of direct weather) surface. Location chosen must
be accessible after installation. When mounted inside a cabinet, the cabinet must be large enough to allow dissi-
pation of heated air. Make sure that there is a minimum of 1” free air space at each end of the unit so that cooling
air can move through the unit properly. AVOID foreign contaminants such as dirt, metal, particles or moisture.
3. MOUNTING.
Flanges with holes are provided for ease of mounting using standard fasteners. Confirm the surface
that the converter is mounted to is solid and will hold the weight (6 lbs) during vehicle operation.
4. ELECTRICALREQUIREMENTS.
A 120 VAC recept
acle needs to be located within 36 inches of the Converter/
Charger to supply power. Electrical consideration should also be given to mounting near the location of the batter-
ies and the
12-volt DC
distribution panel.
5. ELECTRICAL CONNECTIONS.
Be sure to tighten all connections securely. A loose connection can quickly cause
terminals and wires to overheat. Review unit labels for recommended terminal torque values.
WARNING - Avoid Possible Injury or Death
•
The terminal marked
-
or
NEG
is for the RV
12 VDC negative
connection
• The 12 VDC output wiring does not require over-current protection because the Converter/Charger limits current
output. However, all electrical connections need to comply with the appropriate NEC code.
120 VAC
Connection - First confirm that the 120 VAC power source AC circuit breakers are in the OFF position. DO
NOT turn on AC breakers until installation is complete.
•
Using an 8 AWG minimum size copper wire, attach from the vehicle/device chassis to the Converter/Charger
Bonding Lug.
• Using the attached power cord on the Converter/Charger, connect firmly to the 120VAC receptacle.
12 VDC Wiring
- It is important to use the correct wire gage. Use a minimum of 8 AWG size copper wire.
