M SERIES
INSTRUCTION MANUAL
OPERATION
2.6 SAFETY CONDITIONS
M Series cabinets are fitted with:
- circuit breaker for tool protection.
- electronic circuit for monitoring of voltage for
device protection against faulty and overvoltage
(10% of extra power is admissible).
- Venting, filter (must be cleaned frequently to
prevent damage).
Each power control card 16A or 5A is protected by:
- The power control card is protected if supply
voltage exceeds 275 V.
- Quick blown fuses on all phases and neutral protect
the TRIAC against overcurrent draw.
2.7 THERMOCOUPLES
Temperature sensors are connected on the male
HARTING plug (in case of a non-mixed wiring
diagram) located on backside of cabinet. Thermocouples
of J type (Iron-Constantan), or K (Ni.Cr/NiAL), or
auxiliary inputs can be connected. Conform to
polarity diagram as indicated on the wiring diagram.
Some standards define colours for thermocouple
leads, for instance:
J sensors (+ = Iron, - = Constantan):

Wires between J or K thermocouples and connectors
on backside of cabinet must made of the same metal
as the sensor (compensation leads) in order not to
introduce parasite thermocouples.
