6. Commissioning, operation
The electrical connection is to be made according to the sensor connections/pin
assignments shown below:
Thermocouple with terminal block

Single thermocouple
The colour coding at the positive connection to the devices always
decides the correlation of polarity and connection terminal.

6.2 Cable connections

The cable gland must be optimally sealed, to ensure that the required protection class is
reached.
Requirements for meeting ingress protection
Only use cable glands within their indicated clamping range (cable diameter suitable for
■
the cable gland)
Do not use the lower clamping area with very soft cable types
■
Only use circular cross-section cables (if necessary, slightly oval in cross-section)
■
Do not twist the cable
■
Repeated opening/closing is possible; however only if necessary, as it might have a
■
detrimental effect on the protection class
For cable with a pronounced cold-flow behaviour the screw connection must be fully
■
tightened
CAUTION!
The protection class is not valid with armoured cables (stainless steel
■
sheathed)
Seal should be checked for signs of brittleness and, if necessary, replaced
