WARNING
` All lines for connecting the magnetic sensor must be shielded.
` Current linkage: don't connected or removed live.
` Perform wiring work in the de-energized state only.
` Use strands with suitable ferrules.
` Wiring to the screen and ground (0 V) must be secured to a good

Basically, all connections are protected against external interference.
NOTICE
Choose a place of operation that excludes inductive or capacitive inter-
ference influences on the magnetic sensor. When mounting the system
keep a maximum possible distance from lines loaded with interference. If
necessary, provide additional installations including screening shields or
metallized housings. Contactor coils must be linked with spark suppres-
sion.
` Pay attention to the maximum length of the connection cable between
