Conformance to EC Directives
The CP1H PLCs comply with EC Directives. To ensure that the machine or
device in which the CP1H PLC is used complies with EC Directives, the PLC
must be installed as follows:
1,2,3...
1.
The CP1H PLC must be installed within a control panel.
2.
You must use reinforced insulation or double insulation for the DC power
supplies used for I/O Units and CPU Units requiring DC power. The output
holding time must be 10 ms minimum for the DC power supply connected
to the power supply terminals on Units requiring DC power.
3.
CP1H PLCs complying with EC Directives also conform to EN61131-2.
Radiated emission characteristics (10-m regulations) may vary depending
on the configuration of the control panel used, other devices connected to
the control panel, wiring, and other conditions. You must therefore confirm
that the overall machine or equipment complies with EC Directives.

Relay Output Noise Reduction Methods
The CP1H PLCs conforms to the Common Emission Standards (EN61131-2)
of the EMC Directives. However, noise generated by relay output switching
may not satisfy these Standards. In such a case, a noise filter must be con-
nected to the load side or other appropriate countermeasures must be pro-
vided external to the PLC.
Countermeasures taken to satisfy the standards vary depending on the
devices on the load side, wiring, configuration of machines, etc. Following are
examples of countermeasures for reducing the generated noise.
Countermeasures
Countermeasures are not required if the frequency of load switching for the
whole system with the PLC included is less than 5 times per minute.
Countermeasures are required if the frequency of load switching for the whole
system with the PLC included is more than 5 times per minute.
Note
Refer to EN61131-2 for more details.
