After connecting the extension cord to the charger,  proceed to plug the 

extension cord into a nearby 240 VAC GFCI protected (Ground Fault 

Circuit Interrupt) outlet.

Below are manufacturer suggestions for the right size UL or CSA Approved 

grounded extension cord.

i. Up to 50 feet in length use a 3 conductor 18 AWG extension cord.

ii. 50 to 100 feet in length use a 3 conductor 16 AWG extension cord.

iii. 100 to 150 feet in length use a 3 conductor 14 AWG extension cord.
Stop operating the charger immediately if any protective AC and DC cable 

insulation, DC fuse holders or ring terminals have been damaged or compro-

mised. Contact the manufacturer to return the charger for service and repair. 

For contact information, please see the Warranty section.
Stop operating the charger immediately if it has received a sharp blow, direct 

hit of force, been dropped or otherwise damaged in any manner. Contact the 

manufacturer to return the charger for service and repair.
Avoid disassembling the charger. Incorrect reassembly may result in a risk of 

electric shock or fire. Unauthorized attempts to service, repair or modify may 

result in a risk of electrical shock, fire or explosion and will void the warranty.
To minimize the risk of electric shock, unplug the charger from the electrical 

outlet before performing any maintenance or cleaning.
Do not expose AC power cord connection to the rain or snow.

GROUNDING AND AC POWER CORD CONNECTION INSTRUCTIONS

DANGER

Never alter manually the supplied AC cord or plug - If the cord does not fit the 

electrical outlet, have proper outlet installed by a qualified electrician. Improp-

er connection can result in a risk of an electric shock.

DANGER

Prior using the adapter as illustrated in Figure A and Figure B, make sure that the 

The charger should be grounded to reduce the risk of electric shock. The 

charger is equipped with an electric cord having in equipment - grounding 

conductor and a grounding plug. The plug has to  be plugged into 

a 240 

VAC GFCI protected (Ground Fault Circuit Interrupt) outlet 

that is 

properly installed and grounded in accordance with all local codes and 

ordinances.

       

       

a.

This battery charger is for use on a nominal 240-volts circuit, and has a 

grounding pin as illustrated in figure A.  A temporary adapter that is illustrat-

ed in figure B can be connected to a two-pole receptacle in figure B if a 

properly grounded outlet is not available. 

The temporary adapter should 

be used only until a properly grounded GFCI protected outlet can be 

installed by a qualified electrician.

Installation

When connecting each jacketed battery charger cable, make sure it is connected

to only 

one 12 VDC

 

battery

 and observe the polarity and color of all connections:

    • Red Wire to the “+” (Positive) Battery connection

    • Black Wire to the “-” (Negative) Battery connection
The black wire can never be connected to a terminal with red wires and vice 

versa. 

Important: The pair of red and black wires in 1 cable jacket MUST GO TO 

THE SAME 12VDC battery.
