Temperature monitoring
The failure of the single-channel temperature monitor in the device system
may occur, as the result of an error, and might not be detected, even if the
motor is operated within the normal temperature range and load cycle.

Labeling
1.7.1
CE Labeling according to ATEX
The type plate shows:
●
Details about the classification of the motors according to the ATEX di‐
rective 2014/34/EU
●
Technical data
of the motor.
As early as during the installation of the motor, ensure that it is la‐
beled accordingly and that it has a degree of protection that is
sufficient for your application.

Symbol Ex
II
Equipment group II which is suitable for all potentially explosive areas other
than firedamp-endangered excavations
3
Device category 3 means, equipment in this category is intended for use in
areas in which explosive atmospheres caused by gases, vapors, fog, dust/air
mixtures are unlikely to occur or, if they do occur, are likely to do so only infre‐
quently and for a short period only.
G
G = gas
D
D = dust
Ex
The European standard for explosion protection has been applied.
nA
Ignition protection type nA for EPL Gc
tc:
Protection by housing for EPL Dc
T 155 °C
Maximum surface temperature inside and outside the housing, where explo‐
sive gas or dust can occur.
IIIC
Electric devices of group IIIC are intended for use in areas where an explosive
dust atmosphere ("C": conductive dust) must be expected, excerpt areas sus‐
ceptible to fire damp.
Gc
Device protection level (EPL) classification Gc for advanced safety level for
use in potentially gas explosive atmospheres where there is no ignition risk
during normal operation or have any additional safety measures which ensure
in the event of foreseeable faults/malfunctions no iginition risk exists.
Dc
Device protection level (EPL) classification Dc for advanced safety level for
use in potentially flammable atmospheres where there is no ignition risk during
normal operation or have any additional safety measures which ensure in the
event of foreseeable faults/malfunctions no iginition risk exists.
