Danger through electric tension
‣ Do not install or wire the device when it is connected to the power supply.
4.2.1 Connecting the power supply
Damage to device through wrong supply voltage
‣ 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).

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.
