u
During installation, place the connectors vertically so that the coupling nut will not damage the
thread.
u
Observe the coding of the connectors during installation.
If sockets in the device:
u
Tighten the cable plug using 1.3 ± 0.1 Nm.
u
Cover unused connections with protective covers. Tightening torque: 1.3 ± 0.1 Nm
u
Provide all outgoing cables with suitable strain relief after a maximum of 200 mm. Observe the
minimum bending radius of the cables (
Ò
information from the cable manufacturer).
u
Use 81-pole connectors with individually sealed cores to ensure protection rating IP 67.
Only connect the 81-pole connectors when the supply voltage is disconnected. "Hot plugging" is
not permitted.
The ingress resistance of cables that users have cut to length must be guaranteed.
u
For the Ethernet connection, use a minimum category 5 (Cat 5) cable.
The RS-232 interface serves only as a service interface (e.g. for firmware updates).
6.3 Shield connection

Holes for shield connection
To ensure the protection of the device against electrical interference and to ensure the correct
function of the device, the housing has to be connected to the body / GND of the supply using
the shortest possible route.
Otherwise the correct function is not ensured!
u
Connect the device to the ground of the vehicle using the M4 self-tapping screw (included).
Only use the supplied screw for the shield connection on the device to avoid corrosion.
Tightening torque: 3.0 ±0.2 Nm
To avoid contact corrosion on the shield connection of the device, do not use any stainless
steel, copper or nickel-plated materials for the bolting element!
6.4 Fuses
u
The individual electric circuits must be protected in order to protect the whole system.
Automotive spade-type fuses are recommended.
All supply lines of the inputs can be protected within the input groups.
