supply
a
Power port: the point at which a conductor or cable carrying the primary electrical power needed for the
operation of the electronic circuit or the switching element or associated equipment is connected.
b
Signal port: the point at which a conductor or cable carrying information for transferring data or signals is
connected to the electronic circuit or the switching element.
c
Not applicable for extra-low voltage a.c. ports (≤ 30 V) and extra-low voltage d.c. input/output ports (≤ 60 V),
when the secondary circuits (isolated from the a.c. mains) are not subject to transient overvoltages.
d
Applicable only to equipment containing devices susceptible to power frequency magnetic fields.

 IEC 2016
e
Class 2 applies to points of common coupling and in-plant points of common coupling in the industrial
environment in general.
Class 3 applies to in-plant couplings in industrial environment only. This class should be considered when a
major part of the load is fed through converters; welding machines are present; large motors are frequently
started or loads vary rapidly.
The manufacturer shall state the applicable class.
f
The given percentage means percentage of the rated operational voltage, e.g. 0 % means 0 V.
g
The value before the solidus (/) is for 50 Hz and the value behind is for 60 Hz tests.
h
Applicable for a.c. equipment only.
i
Requirements are under study for the future.
k
For keeping the functionality at the system level (e.g. automation or process) the state of the switching
element shall not change for more than 1 ms for d.c. devices or one half-cycle of supply frequency for a.c.
devices.
l
For devices with power consumption of more than 750 mW, the recovery time of the switching element may
be longer than one half-cycle but shall be less than the maximum recovery time.
