IRING
To connect and disconnect a cable, all power sources must be switched off and the batteries isolated.
Checking of the polarity
Before connecting the batteries to the isolator, it is imperative to check their polarity. Also check the battery
voltage using a calibrated voltmeter. A low value of voltage on certain types of batteries may reflect an

For battery cables up to 3 metres, the cross-section of the battery cables should be at least equal to or greater than the
values provided in the table below:

LECTRICAL LUGS
The cable lugs must be crimped with suitable pliers to resist to mechanical vibrations and to avoid overheating.
The dimension must be selected according to the cross sections of the cables and the threaded rods (see table of cable
sections).
They must be fitted with an insulating sleeve to avoid the risk of electric shock.

LECTRICAL PROTECTION CIRCUIT
The electrical protections (fuses) must be placed upstream of the splitter.
They must be sized with the same ratings as your isolator (eg for an RCE/100 -> 100A).
Any non-compliance with these recommendations will result in the systematic cancellation of the guarantee.
