DANGER
Risk of injury from dangerous electrical voltages
When the housing cover of the controller is open, only a safety extra-low voltage of less
than 42 V may be present. The protective cover provided must be used when a higher
voltage (max. 230 V AC) is connected to the relay module. Please follow the procedures
described below for connecting a relay module.

Note
Specifications for connecting the relay module
•
The cables connected must be suitable for the voltage used and have appropriate
(double or reinforced) insulation. Cables with an external diameter of 6 to 7 mm are
recommended.
•
Components of the controller and connecting cable, such as the motor plug and its wires,
may only come in contact with the additional (or reinforced) insulation of the current-
carrying wires.
•
Networks with different voltages (for example 24 V and 230 V) must not be connected to
the relay module.
