NEVER CONNECT/DISCONNECT OR OPEN THE ENCODER WITH POWER ON OR IN DUST ENVIRONMENTS
RESPECT THE MOUNTING TOLERANCES AND THE MECHANICAL RESTRICTIONS IN ORDER TO REMAIN IN LINE WITH THE
MAXIMUM SURFACE TEMPERATURE VALUE ALLOWED BY THE CLASS T4 REQUIREMENTS
LCIE 04 ATEX 6109 X: CE certification of Type for the encoder :
Operating Temperature : -30°C to +70°C
The components of the device are intrinsically safe: they can be used in explosive atmospheres. The supply and output circuits can
only be connected to associated devices which are intrinsically safe and that are certified by type [ia] or [ib]. These devices must
have electrical parameters that have a compatible supply with the above mentioned electronics
LCIE 04 ATEX 6155 X: CE certification of Type for the encoder’s system (encoder associated with a BEI barrier):
Operating temperature: barrier: -20°C to +40°C, encoder: -30°C to +70°C
System classification: Eex ia IIC T4 Ex iaD 20 T135°C. The interconnecting cables have to be sufficiently protected against damage
and have to be separated from the non intrinsically safe circuits. They are described in the norm EN50020 paragraph 6.3, with the
following characteristics C=100pF/m and L=1.2µH/m, or with cables with other C and L values, With respect to the maximum
authorized values:
Gases : Ca=3.9µF and L=0.4 mH
Dust : Ca=38.7µF and L=0.8mH
