11.5 Specifications for dielectric tests, safety class and degree of protection
Test Voltages
During the routine test, the insulation resistance is tested at the following test voltage in
accordance with IEC 1131 Part 2:
Table 11-20 Test Voltages
Circuits with rated voltage U
e
relative to other cir‐
cuits or ground
Test voltage
0 V < U
e
≤ 50 V 500 VDC
Safety class
Safety class I in accordance with IEC 536 (VDE 0106, Part 1), i.e. a protective-conductor
terminal is required on the mounting rail!
Protection against the ingress of foreign matter and water
IP 20 degree of protection in accordance with IEC 529, i. e. protection against contact with
standard probes.
Also: Protection against ingress of solid foreign bodies with diameters greater than 12.5 mm.
No special protection against ingress of water.
