*Cable length ≥2m: Use shielded cables.
**When using ferrules, the maximum cross-section for communic-
ation interfaces is reduced to 1mm

are permissible in the Wilo-Connector.
DANGER
Electric shock!
When connecting SSM/SBM lines, care should be
taken to separate the SELV section, thus ensuring
SELV protection is maintained!
At cable cross-sections of 5–10mm, remove the internal sealing
ring from the threaded cable gland before installing the cable
➜Fig.24.
NOTICE
• Tighten the threaded cable connection M16x1.5
on the control module with a torque of 2.5Nm.
• Tighten nuts to a torque of 2.5Nm to ensure strain
relief.

All communication interfaces in the terminal room (analogue inputs,
digital inputs, Wilo Net, SSM and SBM) comply with the SELV stand-
ard.
Follow the detailed instructions online for details on connecting the
shield clamp.
