Connecting the device

WARNING
!
Danger! Electric voltage!
‣
The entire connection of the device must take place while the device is de-energized.

4.2.1 Connecting the power supply

• 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).
