6 Electrical connection and protective sleeve
assembly
Electrical connection is realized via a special connecting cable only avail-
able at
SCHMIDT Technology that can be purchased as additional op-
tional accessory:
Material nos.: 523565 or 523566
Connecting cable
The sensor must be operated only with a original connecting ca-
ble by
SCHMIDT Technology (optional accessory).
Otherwise, the ATEX suitability is null and void.
Connection on the sensor side is realized by means of a plug-in connector
which has to be protected against impacts and UV radiation by means of
a protective sleeve

. Latter features an ATEX-certified cable entry (1x
M12) and must be installed afterwards (see Figure 6-1).
Protective sleeve for plug-in connector
Must absolutely be mounted!
If the protective sleeve is not mounted professionally, the explo-
sion protection becomes null and void!
It is recommended to connect, first, the connecting cable on the field side
(before, fit protective sleeve on cable, see Figure 6-1).
Other electrical accessories, such as Zener barriers or intrinsically safe
power supplies, are not required for the ATEX operation.
In general the followings apply:
During electrical installation ensure that no voltage is applied
and inadvertent activation is not possible.
This applies in particular when disassembling the sensor.
WARNING!
DO NOT DISCONNECT THE CONNECTING CABLE AND
SENSOR WHEN THEY ARE UNDER VOLTAGE!
WARNING!
