NOTICE! Damage hazard
• The connection to the vehicle's electrical system should be protected by a
40 A fuse for the power supply and a 2 A fuse for the voltage monitor.
• The battery must be capable of supplying the required current and voltage
(chapter "Technical data" on page 16).
• Route the power supply lead stressless and secure it with cable binders in
appropriate intervals.
Connect the unit directly to the battery.
When doing so, you should also follow the vehicle manufacturer's guidelines.

➤ Feed the wiring loom to the right through the roof cupboard to the A-pillar.
➤ Run the wiring loom downwards to the main fuse/relay panel (preferably
along the roof hatch drain hose) and via the body interface to the outside.
➤ Run the wiring loom to the battery compartment along a route where it is
protected.
➤ Connect the power supply negative lead (black) to the battery negative
terminal as illustrated.
➤ Connect the voltage monitor negative lead (black) to the battery negative
terminal as illustrated.
