AS-i Master Module CP 142-2

2-1

2  Technical Description and Installation Guidelines

This chapter outlines the performance of the CP 142-2, explains how to install the module and
introduces you to its basic functions.

You will learn the following:

±

How to install the CP 142-2.

±

Which modes are supported by the CP 142-2.

When handling and installing the module, please keep to the general guidelines for
handling electrostatically sensitive devices and follow the instructions in the ‘ET 200X
Distributed I/O System’ manual /4/.

Insert or remove modules only when the power is turned off.

Noise immunity/grounding
To ensure the noise immunity of the CP 142-2, the ET 200X distributed I/O system and
the AS-i power supply unit must be correctly grounded.

The CP 142-2 cannot be operated with all variants of the basic modules of the ET 200X
distributed I/O system. Please read the accompanying Product Information.

The AS-i power supply unit used must provide a low voltage, safely isolated from the
network. This safe isolation can be implemented according to the following
requirements:

±

VDE 0100 Part 410 = HD 384-4-4 = IEC 364-4-41
(as functional extra-low voltage with safe isolation) or

±

VDE 0805 = EN 60950 = IEC 950
(as safety extra-low voltage - SELV) or

±

VDE 0106 Part 101
