longer than 10 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.
3.6.1 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 install 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 are
essential in order to properly operate the inverter. The soldering cannot provide such connections.

3.6.1.1 Fuse
A main fuse must be installed in the battery casing on the positive cable (+) between the batteries and the inverter, as close as possible
to the batteries. In this way (and in the event of cable rupture), the DC current would be cut at the batteries and would not cause a fire.
