7.3 Selecting the 24 Vdc power supply source
Before starting this procedure, read the specific section in the manual “Technical
Specifications”:
Overview for 24 Vdc power supply in the Control Unit (see par. 6.1 on
page 115).
Preliminary procedures/ notes
The JP200 connector is supplied with earth connection by terminal 5
to connect the 0V to the equipotential circuit. The removal of this
connection neutralizes the solution for the faults towards earth (EN
60204-1 § 9.4.3.1)
Operating procedure
a. Select the 24 Vdc power supply source according to the reference wiring diagram
in Fig. 7.1 - Circuit to select the 24 Vdc source: power supply source selection
reference diagram on page 63.
b. Depending on the power supply source selected, consider the following aspects:
•an internal power supply source does not require any device and the
selection on the JP200/SDM connector is already correct (position A in
Fig. 7.1).
•an external power supply source requires an external powering device
(not supplied together with the Control Unit) that shall be connected through
the X30/CIP connector: pins (see par. 6.6.3 on page 54). The selection on
the JP200/SDM connector is requested (position B in Fig. 7.1).
