7.4 Electrical Connection
The supply voltage is between 12 and 30 V. The power supply and the output signal
are transmitted via a two-wire cable (max. 12 mm outer diameter, max. 14 AWG) and
connected in accordance with the pin configuration.
Supply voltage can be supplied by a power unit, a transmitter power supply or by
means of a PLC connection.
It is suggested to use a model with integrated lightning protection for preventing
damage due to voltage peaks.
For the dust approval version, only cable glands and blind plugs with the
appropriate ATEX approval may be used. The M12x1 plug may not be used
in conjunction with dust approval.(See chapter 2.2)
Please observe local installation regulations (Germany: VDE-Standard).
The terminal voltage should not exceed 30 V.
The transmitter is only to be connected to approved intrinsically safe
measuring instruments.
When selecting a cable make sure that it complies with the capacity and
inductivity values as well as the voltage resistance values
(see “Technical Data” on page 103).
The given operating temperatures must not be exceeded.
For the connection of the cable the leads must be covered by end bush-
ings. The cable must not be damaged.
