10.3.1 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 Type 3360 or 3361 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 mm
