Installing the CP

Note
When installing and handling modules, please keep to the ESD guideli-
nes.
Insert or remove modules only when the power is turned off.
Installation
The CP is plugged into any slot (see Section 2) of the PLC. It is then secured
by the screws in its casing.
The module is attached to the AS-i cable via the terminals of the front con-
nector that is plugged into the CP. Contact is made at terminal pair 17, 18 or
19, 20 of the front connector. Terminals 17 and 19 and terminals 18 and 20
are electrically connected by the CP 343-2 / CP 343-2 P.
The assignment of the terminal pair and the polarity are indicated on the front
panel of the CP. The second terminal pair is intended for connecting the AS-i
power supply unit or a branch of the AS-i cable. The AS-i power supply unit
can, however, be connected to any point on the AS-i cable.
Note
Noise immunity / grounding
To achieve the noise immunity of the CP 343-2 / CP 343-2 P, the PLC and
AS-i power supply unit must be correctly grounded.
