For USA and Canada:
The supply must be limited to:
a) max. 5 A at voltages from 0-20 V DC, or
b) 100 W at voltages from 20-60 V DC.
The limiting component (e.g. transformer, power supply or fuse) must be certified by an
NRTL (Nationally Recognized Testing Laboratory).

For loading the internal capacitors, power consumption may be increased for a short time
(in the microsecond range). his value is dependent on the input voltage and impedance of
the power source.

If this S-DIAS Safety module is connected to several modules, the total current for the
+24 V and + 12 V must be mathematically determined via the module documentation of the
S-DIAS Safety CPU modules used! The total current of the +24 V supply cannot exceed
800 mA. The total current of the +12 V supply cannot exceed 800 mA.
If the SCP 111-2 with a firmware version lower than V431 or with a safety number
lower than S01.03.01 is integrated with safety I/O modules in the S-DIAS system (blue
modules), the voltage increase of the +24 V supply of the SCP 111-2 must not occur
later than 100 ms after the voltage supply of the S-DIAS supply module, otherwise
the SCP 111-2 may not recognize the safety I/O modules on the safety bus. This
causes a safety error (Error code 1009, Reason code 15 in the Safety Designer) and
the safety application is not started.
