Electrical wiring
Detailed wiring diagrams are available as aids to install the electrical wiring. Where possible,
pre-assembled wiring harnesses are delivered.
ATTENTION
In order to avoid damage to the electrical signal of the machine, the
supply line such as the +15 (red wire, pin 1) and the hydraulic hammer
control signal line (green wire, pin 3) must be protected with the correct
fuses. Consult the table below or the wiring diagrams for the correct fuse
ratings.
• Connect the wires only when the main components (pump unit, signal lamp and optional
hammer shut-down valve or relay) have been installed.
• Lay the wiring as far as possible along the passage of the existing electrical wiring and fas-
ten them with small or large straps.
• Always make wire connections in the cabin or in a watertight terminal box.
