10.4 External connections

All external connections are made on terminal board PEL (low current)

and connection terminal blocks.

B High and low current cables should be routed separately in order to

avoid interference on the sensors (minimum distance of 100 mm).

B Use the following cable area when extending the temperature sensor

cable:

– Up to 20 m long cable: 0.75 till 1.50 mm

– Up to 30 m long cable: 1.0 till 1.50 mm
