To avoid additional temperature increase, the devices should not be exposed to direct exposure to sunlight when in
operation!
EU design type test certification for the installed inductive proximity switches:
PTB 99 ATEX 2219 X
The integrated proximity switch is indicated on the type label/wiring diagram.
The surrounding housing has protection class IP65 as per EN 60529.
For use in explosion risk areas, the devices must be connected to certified intrinsically safe power circuits:
Max. voltage U
max
= 16 V
Max. current I
max
= 25 mA
Max. power P
max
= 64 mW
Device data (per contact):
max. internal capacitance Ci max = 30 nF
max. internal inductance Li max
= 100 μH
The permitted limit values for U
i
, I
i
and P
i
for the intrinsically safe feed power circuits depend on the proximity switch
type. They are to be found in the respective EU design type test certifications.
For the non-electrical part of the devices, the standards EN 1127-1 (2007), EN 13463-1 (2009) und EN 13463-5
(2011) are applicable with regard to explosion protection. The relevant requirements of these standards are satisfied.
The documentation for the mechanical part has been filed with TÜV-Nord-Cert (see declaration of conformity).
