8.3.1 Safety instructions
WARNING!
Risk of injury due to improper installation.
▶ Installation may be carried out by authorised technicians
only and with the appropriate tools.
▶ Observe general engineering standards & rules during
installation.
Risk of injury due to unintentional activation of the system
and uncontrolled restart.
▶ Secure the system against unintentional activation.
▶ Following installation, ensure a controlled restart.
Use of set-point input 4...20 mA
If several devices are connected in series and the electrical
power supply for a device in this connected series fails, the
input of the failed device becomes highly resistive. As a
result, the 4...20 mA standard signal fails.
NOTE!
To ensure electromagnetic compatibility (EMC) the functional
earth must be connected to earth with a short line (max. 1 m).
Functional earth must have a cross-section of at least 1.5 mm².
8.3.2 Access to connection terminals
To access the terminals, open the device as described below.
1. Remove display module or blind cover:
WARNING!
Carefully remove the display module so that the connection
cable and HMI interface are not damaged.
Devices with ATEX approval or IECEx approval are
secured with a magnetic lock.
The removal of the cover is described in the supple-
mentary instructions for the electromotive control valves
with ATEX approval and IECEx approval.
