Ground 

The inverter has a lug on the rear panel that must be connected, using a #8 AWG copper cable, to the chassis of your vehicle or to 
a metallic panel connected to the chassis. This grounding procedure conforms to most electrical codes that require to derived AC 
sources to ground in case of malfunctioning. To make sure that you found a good grounding point, run a 24 volt test light from the 
positive terminal of your battery to your grounding point.  If the light comes on, your installation is more than likely OK. 

 
WARNING!  

Do not operate the inverter if the ground screw of the inverter is not properly connected to the chassis 
of your vehicle, it may result in electrical shock hazard.

Battery cables 

Proper wiring is very important for safe and proper operation of the inverter (see 3.1). Since the inverter has a low voltage (24 
volts) and a high current input, low resistance wiring and connections between the batteries and the inverter is essential in order to 
deliver the maximum amount of usable energy to your load. Don’t waste the investment you have made in a highly efficient 
inverter by using cheap and undersized cables! 
 
Use only covered, flexible, copper wires capable of withstanding temperatures in excess of 215° Fahrenheit. As included in our 
CM series kits, we recommend welding cables as the best size & type for connection between the batteries and your inverter. Keep 
the cable length as short as possible, no longer than 12 feet. This will ensure that the overall system efficiency is as high as 
possible, and will keep the voltage drop between the batteries and the inverter to a minimum. If the voltage drop is too excessive, 
the inverter may shut down.

Preparation of the cable connected to the “positive” end

 

Measure and cut the length of cable necessary to connect the positive (+) end of the battery to that of the inverter, not forgetting 
the length needed to allow movement due to the suspension of the cabin. The cable must be cut in two pieces, of which the small 
part must be six inches (Figure 5). 
 
Strip a half-inch off each of the four cable ends, insert the longer section of the cable in a PVC strain relief, and intall good quality 
tin plated terminal lugs on the bare wires. Crimp the terminals with a hand held crimping tool (the use of locked pliers (

Vice-Grip

is not recommended), until the entire cable is crimped, and then cover each section of bared wire with good quality RED 
shrinkable tubing (Figure 4).  
 

CAUTION!  

Do not solder the terminal lugs to cables.  Solid and low resistance connections to the DC power 
source is essential in order to properly operate the inverter. The solderings cannot provide such 
connections.
