Details of insulation testing, safety class, degree of protection
and rated voltage of the ET 200X
Test voltage
Insulation strength is demonstrated in the routine test with the following test
voltage in accordance with IEC 61131-2:
Circuits with rated voltage U
circuits and ground
300 V < U
Pollution severity
Pollution severity 3 in accordance with IEC 61131
Safety class
Safety class I in accordance with IEC 60536
IP 65 degree of protection
Degree of protection IP 65 in accordance with IEC 60529 for all basic and
expansion modules, EM 148-FC frequency converters, motor starters and
pneumatic components of the ET 200X. This means:
S Protection against the ingress of dust and complete protection against electric
shock
S Protection against water jets from nozzles which are aimed at the casing from
all directions. (There must be no harmful effects from the water.)
IP 66 and IP 67 degrees of protection
Degree of protection IP 66 and IP 67 in accordance with IEC 60529 for all basic
and expansion modules (except motor starters, EM 148-FC frequency converters
and pneumatic components):
S Protection against the ingress of dust and complete protection against electric
shock
S IP 66: Protection against heavy seas or strong water jets. (There must be no
ingress of harmful quantities of water into the casing.)
S IP 67: Protection against water when the casing is immersed in it under defined
pressure and time conditions. (There must be no ingress of harmful quantities
of water into the casing.)
