6 Electrical connection and protective sleeve
assembly
The electrical connection is realized by means of a special connecting
cable only available at
SCHMIDT Technology (material no.: 524921 or
524942 and 524929) that can be purchased as additional optional ac-
cessory.
Connecting cable
The sensor must be operated only with the original connecting
cable by
SCHMIDT Technology (optional accessory). Other-
wise, the ATEX compliance is null and void.
Other electrical accessories, such as Zener barriers or intrinsically safe
power supplies, are not required for ATEX operation.
In general the following applies:
Make sure that no operating voltage is active during electrical
installation and that the operating voltage cannot be switched
on inadvertently.
This applies in particular to disassembly of the sensor.
WARNING!
DO NOT DISCONNECT THE CONNECTING CABLE FROM
THE SENSOR UNDER VOLTAGE!
WARNING!
DO NOT OPEN PROTECTIVE SLEEVE UNDER VOLTAGE!
It is recommended to connect, first, the connecting cable on the field side
(first, connect the protective sleeve to the cable, see the following de-
scription).
The connection on the sensor side is realized by means of a plug-in
connector to be mounted subsequently, it must be protected against
impacts and UV radiation by means of a protective sleeve with cable
entry (1 x M12) included in the delivery (for assembly procedure refer to
Figure 6-1).
Protective sleeve for plug-in connector
Must be mounted!
If the protective sleeve is not mounted properly, the explosion
protection is not available!
