Mains connection
- Follow the rating plate for the mains connection.
- Make sure that the mains power supply has a clockwise-rotating field.
- Follow the local regulations for earthing.
Temperature monitoring connection
- Connect the bimetallic sensors through an evaluation relay with an approval for explosive atmospheres. Recommendation: relay “CM-MSS”.
- Connection values: max. 250 V~, 2 A, cos φ = 1.
- When the threshold is reached: Switch off the motor with a manual reactivation lock (which can be reset by hand only).
Leakage detection connection − motor compartment
- Connect the moisture probe through an evaluation relay. Recommendation: relay “NIV 101/A”.
- The threshold is 30 kOhm.
- When the threshold is reached: Activate an alarm or switch off the motor (recommended).
Leakage detection connection − sealing chamber
- Connect the moisture probe through an evaluation relay with an approval for explosive atmospheres and an intrinsically safe circuit. Recommendation: relay “XR-4...”.
- The threshold is 30 kOhm.
- When the threshold is reached: Activate an alarm or switch off the motor (recommended).
