• The plug connector is suitable for the connection of solid wire or single or
multi-strand conductors of cross-sections between 0.14 and 2.5 mm². The
length of the free wire should be between 8 and 9 mm. It is not necessary to
use ferrules.

Before removing the protective cover, switch-off the controller and remove the
connectors.
Warning
All controller terminals carry mains potential. It is therefore necessary that
all input and output signals required for the control of the controller are,
electrically, safely separated by measures outside the controller and have
another protection against direct contact (double basic insulation).
When using the supplied set-value potentiometer the mechanical fixing
must have an additional PE connection and the connections must be
insulated and covered.
Prior to commissioning make sure that there is no earth fault in the connecting
cables. The protective conductor must only be connected to the PE connection
(6.3-mm spade connector). PE or ground connections to any other terminals
cause a controller failure.
Screen motor cables A, B, I and K as well as the control cables. The screen
must be connected at both ends to the central PE connection. The control
cables must not be longer than 10 m. Check the voltage rating of the screened
cable.
To ensure that the screening is effective, it should not be opened or interrupted.
It should also be laid as close as possible at the cable ends. Connect the
screening of the motor cables to PE in the motor terminal box.
