DP/AS-Interface Link 20E

Release 11/2002

C79000-G8976-C138–04

1.1

General Notes on Operation – Safety Warnings

!

Caution

When handling and installing the DP/AS-i Link 20E module, make sure that you
adhere to the ESD guidelines.

The DP/AS-i Link 20E module must only be connected when the AS-i power
supply unit is turned off.

!

Caution

Noise immunity/grounding

To ensure the noise immunity of the DP/AS-i Link 20E module, both the
DP/AS-i Link 20E module and the AS-i power supply unit must be grounded
correctly.

!

Caution

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:

S

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

S

VDE 0805 = EN60950 = IEC 950
(as safety extra-low voltage SELV) or

S

VDE 0106 Part 101

Note

The DP/AS-i Link 20E module can be configured, installed and started up
independent of the PROFIBUS installation.
