Warning!
Electric shocks can cause death or serious injury.
Proceed with extreme caution when working with cables and terminals. If the
device/measuring system is installed in a high-voltage environment and a malfunction or
installation error occurs, high voltage can be present at the terminals or the device/measuring
system itself.
1.1

Designated use

• The device is a universal and configurable temperature field transmitter with one temperature
sensor input for resistance thermometers (RTD), thermocouples (TC) and resistance and
voltage transmitters. The unit is designed for mounting in the field.
• Using the device for any purpose other than that described jeopardizes people's safety, and the
safety of the entire measuring system, and is therefore not permitted.
• The manufacturer does not accept liability for damage caused by improper or non-designated
use.
