Supply power to the control unit from external resource.
It is possible to divert a voltage of RS–232–C device at CP1 to CP2 for
use in units, such as a CRT and MDI, that are designed to operate on 24
In this case, the external 24 VDC power supply should have a rating which
is equal to the sum of the current consumed by the control unit and the
current used via CP2.

The stud for the protection ground is located at the rear of the setting and
display unit (such as a CRT/MDI) installed in the cabinet. Use a twisted
