Eberspächer B1L Installation Instructions Manual - page 11
Electrics:
Arrange electric cables, switches and control units in the vehi-
cle in such a way that their correct functioning cannot be im-
paired under normal operating conditions.
Fit the control unit so that it is protected from splash water
(from both its own vehicle and preceding ones). Outside
installation is thus not permissible. The unit is best arranged in
the vehicle interior, with the plugs pointing downward.
The pilot light (built into the switch or timer) should be within
the field of vision of the driver, or at least be visible to him
without great effort.
Install the room thermostat where it is sheltered from draughts
and sunlight. Do not fit it to non-insulated outer walls.
The following cable cross-sections must be observed between
battery and heater, in order that the maximum permissible
voltage losses in the cables (0.5 at 12 V rated voltage and 1 V
at 24 V) are not exceeded.
L+ + L- < 5 m - cross-section 4 mm2
L+ + L- 5 to 8 m - cross-section 6 mm2
If the positive cable is to be connected to the fuse box (e.g.
terminal 30), the vehicle's cable too from the battery to the fuse
box must be included in the calculation of the total line length,
and if necessary redimensioned in accordance with the above.
Smear plug and earth connections with contact protection
grease outside the vehicle interior.
