8 - INSTALLATION INSTRUCTIONS

8.1 - Directions for installation

• After unpacking, ensure the integrity of the device.
• It is the installer's responsibility to guarantee the integrity and suitability of the actual installation,
particularly the use of suitable tools and accessories for the wiring as well as the correct use thereof
in accordance with the following instructions and current regulations, and in particular in accordance
with the ADR regulations.
• The electrical cables 31A – battery negative and 31 – system positive must, after installation, be completely
insulated from each other; therefore, even a single possible bypass between these two electrical cables
at any other point of the vehicle, perhaps in correspondence with a device, will cause operation failure of
the battery switch.

M8 hexagonal cylinder head embedded screws, with washers under the screw heads; for the
drilling template see the relative page.
• The installer must carry out the installation in such a way as to guarantee an IP54 protection level
(in accordance with IEC 60529 regulations) for the battery switch connection wiring.
• P , P (with relative protection), S
0-(ON) 0-(OFF)1
