8 EMC AND LOW VOLTAGE DIRECTIVE

1) Be sure to ground the cable shield that is connected to the CC-Link

module close to the exit of control panel or to any of the CC-Link stations

within 30 cm (11.81 inch) from the module or stations.

The CC-Link dedicated cable is a shielded cable. As shown in the

illustration below, remove a portion of the outer covering and ground as

large a surface area of the exposed shield part as possible.

2) Always use the specified CC-Link dedicated cable.

3) Do not use a ferrite core for the CC-Link module or CC-Link stations.

4) The CC-Link module, the CC-Link stations and the FG line inside the

control panel should be connected at both the FG terminal and the SLD

terminal as shown in the diagram below.

(d) I/O signal lines

For the I/O signal lines, if extracted to the outside of the control panel, also

ensure to earth the shield section of these lines and cables in the same

manner as in item (1) above.

(2) Power supply module

The precautions required for each power supply module are described below.

Always observe the items noted as precautions.

Model Precautions

A1S61P
A1S62P

Not usable

A1S63P ( 1)

Use the CE marked 24VDC panel power equipment.

A1S61PEU
A1S62PEU
A1S61PN
A1S62PN

Always ground the LG and FG terminals after short-circuiting them.

( 1) If sufficient filter circuitry is built into the 24VDC external power supply module, the noise

generated by A1S63P will be absorbed by that filter circuit, so a line filter may not be
required.
Filtering circuitry of version F or later of A1S63P is improved so that a external line filter is
not required.
