SAFTEY ALERT
FOR YOUR SAFTEY, READ ALL INSTRUCTIONS BEFORE INSTALLATION AND OPERATION.
INSTALLER: Provide these instructions to the end user or consumer.
CONSUMER: Keep these instructions for future reference.
NOTICE: Products are not to be used nor are warranted in aerospace, medical or life safety applications.
WARNING - Avoid Possible Injury or Death
120 VAC is present. This Converter/Charger is designed to convert 120 VAC to 12 VDC. It also provides low voltage power
for charging on-board 12 VDC batteries. The Converter/Charger is a “switch mode” type and is designed to be maintenance-
free with no user serviceable components. The Converter/Charger power output is “current limiting” by design.
WARNING - Avoid Personal Injury or Death
NEVER store electrical devices in compartments where ammable liquids (such as gasoline) exist.
DO NOT mount/install unit in compartments designed for storage of batteries or ammable liquids.

1.0 Installation and Maintenance
1. DISCONNECT DC POWER. Disconnect the battery POS (+) 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. Conrm 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 receptacle 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 conrm 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 rmly 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.
• The terminal marked + or POS is for the RV 12 VDC positive connection

6. BATTERY CABLES. This model includes 6 Gauge, 15’ battery cables, CCI code 08566. The cables are rated
at 250 Amp current with 400 Amp clamps, polarity indication label, TPE Insulation (-40°C to +60°C), tangle free
design. SPECS: Ø0.32MM*150STRANDS*OD.9MM.
7. TEST. First, disconnect the POS (+) clamp from the battery or load. Second, attach a multimetre instrument
between the positive and negative clamps of the Converter/Charger. Then energize the 120 VAC converter
circuit. Test for proper output power using the multimetre. Measure the output voltage from the positive and
negative clamps. The voltage should read 13.6 +/-0.2 VDC.
8. BATTERY. With the 120 VAC disconnected, reconnect the POS (+) clamp to a known good battery. With the con-
verter 120 VAC energized, measure the voltage at the converter and at the battery. The voltage should be about
the same. When connected to any charging source all batteries will “gas” and lose some uid.
WARNING - Avoid Personal Injury / Product Damage
9. HI-POT TESTING. (Vehicle/device Manufacturing Facilities Only) DO NOT hi-pot DC wiring with the Converter/
Charger connected to the vehicle/device wiring in order to prevent serious injury and/or damage.
2.0 Trouble Shooting
NOTE: Before removing and replacing the Converter/Charger, perform the following checks:
a. Disconnect the AC power from the Converter/Charger.
b. Disconnect the Battery from the Converter positive +output clamp.
c. Re-connect the AC power to energize the Converter.
d. Using a voltmeter, measure the voltage at the Converter - and +Output clamp.
• The Converter is OK if the voltage reading is between 13 VDC and 14 VDC (typically 13.6 VDC)
• Otherwise check the table on the following page:
