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 (mains connection), a switch marked as a separator, as well as an
overvoltage organ (rated current
to reach).

4.2.2 Connecting external sensors
Note!
Active and passive sensors with analog, TC, resistance and RTD sensors can be attached to the
device.
Depending on the type of signal of the sensor in question, the terminals can be freely selected which
means the process display unit can be used with great flexibility.
