11.6 Sensor wire connection, EMC cable with standard
sensor set
With the EMC version, the sensor wires are not cable-tied to the
cable bracket, but a P-clamp (CL1) is used to earth the cable shield.
Place the P-clamp onto the shield of the signal wires, ensure that it
is positioned 5 ± 2 mm (0.196 ± 0.078 in) from the end of the shield.
Mount the clamp on the bracket. Ensure that a suitable anti-seize
grease is used on the screw. The required torque is 4 ± 0.6 Nm (3 ±
0.4 lb-ft).

11.7 Sensor wire connection, single cable with sensor
set 1
Sensor set 1 is different from the standard sensor set as it has a
Pt1000 sensor mounted on the stator.
1. To complete the wiring of a single cable with sensor set 1, first
complete all the wiring steps of the standard sensor set. Ensure
that the wiring for the Pt1000 is kept in front of the cable
bracket.
2. The wiring of the Pt1000 sensor is secured to the cable bracket
by a clamp.
3. Place the cable shield below the camp.
4. Secure the clamp. The required torque is 1 ± 0.15 Nm (0.7 ± 0.1
lb-ft). Use a suitable anti-seize grease on the screw thread.
