6. SEPARATE INSTALLATION
If you prefer to install the control unit 844 MPSR separately from
the operator, use the 844 INTERFACE card and the adapter
cable (provided with the geared motor) and connect them
together as shown in fig. 11.
The surge capacitor can be coupled either to the control
unit (J6) or to the interface card (J5).
Important:
make sure that the cable colour code is
respected when connecting the electric motor.
Install the control unit 844 MPSR in a box with
minimum housing protection IP55.
