Connecting the engagement motors
The positive connection (r) of the 2-wire motor connection
cables has been marked with a red longitudinal line along the
cable insulation.
Mark motor cables A + B and route to control unit (shorten
cables to same length if necessary).
Slide the flat connector sleeve insulation over the
cables (e.g. black for motor A and transparent for motor B).
Crimp on flat connectors, slide on flat connector insulation
and connect as shown in connecting diagram.
Connecting the battery
Liquid electrolyte batteries must be installed in a separate box
with ventilation leading to the outside. The fuse in the positive
lead must be connected outside the box. A separate box is
not required for gel or AGM batteries. Pay attention to the bat-
tery manufacturer's installation instructions.
The outgoing lines from the terminals must be routed with a
gap between them until after the fuse in the positive lead.

Route the battery connector cables (only use the original
Truma cables supplied) to the control unit and attach them
securely using the clips and screws provided.
The battery connector cables must not be extended.
They must be routed separately from the motor cables,
and must not run over the control unit.
Route battery connector cables so that they do not chafe (par-
ticularly at leadthroughs through metal panels). Use suitable
protective leadthrough bushing to prevent damage to cables.
Connect battery connector cables to the existing battery ter-
minals (red = positive, black = negative).
Incorrect polarity will destroy the electronics / control unit
The connection to the control unit (as per the connecting dia-
gram) must be made in the order: nut, battery connection ring
eyelet, nut (torque: 7 Nm ±1).
Connect fuse in the positive lead (150 A) near the positive
terminal.
Connecting the safety socket to the
micro switch
Lead the provided 2-wire cable with the flat connectors
through the socket holder (g) and the rubber sleeve (h).
If necessary, open cover and push socket connection out of
socket housing (i).
Connect 2-wire cable with flat connectors to micro switch.

If necessary, insert socket connector back into socket housing (i).
Screw socket housing (i) with rubber seal (h) to socket holder (g)
using 3 sheet metal screws (j). (Several positions are possible by
selecting the mounting holes on the socket holder and rotating
the rubber seal)
Lead cable loosely through the strain relief (k) and screw in
place with the 2 sheet metal screws. Depending on the instal-
lation situation, the cable can be led out of the socket holder
through one of the three recesses.
