4.4.1 Fitting cable to DC plug
NOTE
Soiled, displaced, or damaged seals impair the strain relief and the imperme-
ability.
►
Do not soil, shift, nor damage the seals during DC plug assembly.
1. Strip 15 mm of cable end of cable (1).
2. Release spring (2) upwards.
3. Introduce stripped cable end into the
DC plug until the cable end becomes
visible underneath the spring (2).
4. Press spring (2) against the stripped
cable end until it engages audibly. En-
sure that the cable end is securely fastened.
5. Slide union nut (4) onto inset (3) of the DC plug.
6. Hold inset with a size 16 wrench and tighten the union nut (4) with a wrench, applying
a tightening torque of 2 Nm.
4.4.2 Preparing data connecting cable
You can use a standard cable (patch cable, CAT4) suitable for outdoor operation or an
alternative RS485 data connecting cable for the data connection. Observe section 3.9.4
when manufacturing an alternative data connecting cable.
