Maximum connection cross section: 1.5 mm²
Minimum connection cross section: 0.2 mm²
Maximum tightening torque: 0.22 Nm (1.9 lbf in)
Control cable capacitance
Maximum control cable capacitance: 330 pF/m
Insulated end sleeves
Insulated end sleeves according to DIN 46228-4 must be used.
Strain relief
For strain relief, the cables to the Control Unit and to the terminal X41 must be fastened to
the lugs in the cable duct below terminal X9 (e.g. with cable ties).
If the cables are introduced at the side (at the height of terminal X9), the strain relief must be
provided outside the Power Module.
