4.4 Electrical installation
Destruction of parts of equipment and loss of regulation control
` All lines for connecting the magnetic sensor must be shielded.
` Never wire or disconnect electrical connections while they are live.
` Perform wiring work in the de-energized state only.
` Use strands with suitable ferrules.
` Wiring to screen and ground (0 V) should be done star-shaped and
with a large surface area. Ensure that the connection of the screen and
potential equalization is made to a large surface area (with low imped-
ance).
` Check all lines and plug connections before switching on the device.
` Switch on operating voltage together with the downstream electronic
unit (e. g., control unit).
Destruction of the magnetic sensor
Destruction of the magnetic sensor through touch or connection of sig-
nal lines.
` The signal lines Data+/Data-/Cycle+/Cycle-/DÜA and DÜB are on 5 V -
level and must neither get in touch nor be connected with UB.
Basically, all connections are protected against external interference.
Choose a place of operation that excludes inductive or capacitive inter-
ference influences on the magnetic sensor or its connection lines. 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 suppression.
