2.6 Notes on wiring
Correct wiring in accordance with the information in the accompanying description
and local regulations is essential. Take particular care to ensure that the AC supply
is not connected to the sensor input or other low-voltage inputs or outputs.
Use copper wire (except for the sensor connection) and ensure that all supply leads
and connection terminals are dimensioned to suit the relevant current rating.
When connecting the controller and selecting the wiring materials to be used, it is
essential to comply with the provisions of DIN VDE 0100 “Erection of power instal-
lations with rated voltages below 1000” or the relevant national regulations.
Furthermore, all connections must comply with the relevant VDE regulations or cor-
responding national regulations.
Wiring of the digital inputs:
Only the output signal of the control at terminal 38 can be connected to the digital
inputs (via potential-free switch contacts)!
Make the connection according to the wiring diagram on the next page.
Use cable bushes
Make sure that cables do not chafe!
Observe relay current rating!
Do not wire digital inputs with external voltage!
Use potential-free switches.
