SIZE OF THE ELECTRICAL CABLES
Always use cables of a suitable cross-section. The minimum cross-sections are listed in the table
below:
Cross-
section in
mm²
AWG section Max 12 V cable length m/ft Max 24V cable length m/ft
2.5 13 2.5/8 5/16
4 11 4/13 8/26
6 9 6/19 12/39
10 8 10/33 20/66
For system protection, the fuse must be installed in the positive wires (+) as close as possible to
the battery. We recommend using 15 A fuses for 12 V and 7.5 A fuses for 24 V. If using a main
switch, it must be able to withstand a minimum current of 20 A. Avoid extra junctions in wiring to
prevent voltage drops that can inuence battery protection settings.
AC: Power cables should be connected to zones L and N on the electronic control unit. Rated
Voltage 100-240 VAC 50/60Hz. Max. safety limit 270 VAC and min. safety limit 80 VAC. A 4 A fuse
must be installed on the cable (L) to protect the installation. If using a main switch, it must be able
to withstand a minimum current of 6 A. The wire size must be min. 0.75 mm
2
or AWG 18.
Note: ground connection can be used if necessary.
