Conformance to EC Directives
xv
1 The units are designed for installation inside control panels. All units must
be installed within control panels.
2 Use reinforced insulation or double insulation for the DC power supplies
used for the communication power supply, internal circuit power supply,
and the I/O power supplies. Ensure that stable outputs can be provided
even if a 10 ms interruption occurs at the input.
3 The CJ1W-PNT21 PROFINET IO Controller Unit meets the generic
emission standard. However as EMC performance can vary in the final
installation, additional measures may be required to meet the standards. It
should therefore be verified that the overall machine or device also meets
the relevant standards. You must therefore confirm that EC directives are
met for the overall machine or device, particularly for the radiated emission
requirement (10 m).
