Connection to a C￿￿H Make the connection to the CPU unit with an I/O connecting cable. The following restrictions apply to this connection.

Only one CPU unit can be connected.

Up to two I/O units can be connected to one CPU unit. However, it is not possible

￿to connect an I/O extension unit.

It is not possible to connect a C￿￿H I/O unit after a C200H interface unit. The C200H interface unit must be the final element in the system.

Note When making a connection to a C￿￿H, a noise filter must be installed.

1.Insert the noise filter in the power supply line of the C￿￿H.

2. Make the distance between the noise filter and the C	H as short as pos-
sible, and separate it from the power supply line.

3.Connect the case of the noise filter to the FG face.

4.For the noise filter, use a ZGB2202-01U made by TDK or equivalent.
