NOTICE
The profile sensor must be grounded on the flat plug on the
electronics housing.
Connection types
The sensor must be connected directly with the control system
according to wiring diagram:
Input voltage
BUS
BUS
4.6 Electrical connections
The placement of the sensor and cabling have a decisive influence on
the sensor’s EMC resistance. Hence correct installation of this active
electronic system and
the EMC of the entire system must be protected by using suitable
metal connectors, shielded cables and grounding.
Overvoltages or faulty connections can damage its electronics despite
protection against wrong polarity
NOTICE
Do not make connections under voltage!
Instruction for connection
– Low-resistance, twisted pair, shielded cables should be used
and the shield should be connected to earth externally in the
evaluation electronics
– Control and sign leads should be kept separate from power cables
and sufficiently far away from motor cables, frequency inverters,
valve lines, relays, etc.
– Use only connectors with metal housing and connect the shield to
connector housing.
– The connection surface at both shield ends should be as large as
possible.
– Keep all non-shielded leads as short as possible
– The earth connection should be as short as possible with a large
cross section. Avoid ground loops.
– With potential differences between machine and electronics earth
connections, no compensating currents are allowed to flow across
the cable shield.
Notice:
– install potential compensating lead with large cross section, or use
cables with separate double shielding, and connect only one end
of shield.
– Use only stabilized power supplies in compliance with the specified
connecting values.

Pins 2 and 4 on the M8 Input Voltage connector are only used to reset the
sensor to DHCP mode. They should be independent of each other and floating
(not grounded) under normal operation.
