1 Safety instructions
Safe operation of the process display unit is only guaranteed if these Operating Instructions have
been read and the safety instructions have been observed.
1.1 Designated use
The process display unit analyzes analog process variables and depicts them on its multicolored
display. Processes can be monitored and controlled using analog and digital outputs and limit relays.
The device provides the user with a wide range of software functions for this purpose.
Power can be supplied to 2-wire sensors with the integrated transmitter power supply.
– The device is seen as an associated electrical apparatus and may not be installed in hazardous
areas.
– The manufacturer does not accept liability for damage caused by improper or non-designated use.
The device may not be converted or modified in any way.
– The device is designed for installation in a panel and may only be operated in an installed state.
1.2 Installation, commissioning and operation
This device has been constructed to state-of-the-art technology and meets all applicable standards
and EU directives. The device, however, can be a source of application-related danger if used
improperly or other than intended.
Installation, wiring, commissioning and maintenance of the device must only be carried out by
trained technical personnel. They must have read and understood these Operating Instructions and
must follow the instructions they contain. The information in the electrical wiring diagrams (see
Section 4 'Wiring') must be observed closely.
1.3 Operational safety
Technical improvement
The manufacturer reserves the right to adapt technical details to the most up-to-date technical
developments without any special announcement. Contact your local sales center for information
about the current state of and possible extensions to the Operating Instructions.
1.4 Return
For a return, e.g. in case of repair, the device must be sent in protective packaging. The original
packaging offers the best protection. Repairs must only be carried out by your supplier's service
organization.
!Note!
Please enclose a note describing the fault and the application when sending the unit in for repair.

4.2 Connecting the device
"Caution!
Do not install or wire the device when it is connected to the power supply. Failure to comply with
this precaution can result in irreparable damage to the electronics.
4.2.1 Connecting the power supply
"Caution!
• Before wiring the device, ensure that the supply voltage corresponds to the specification on the
nameplate.
• For the 90 to 250 V AC version (power supply connection), a switch marked as a separator, as
well as an overvoltage organ (rated current ≤10 A), must be fitted in the supply line near the
device (easy to reach).
