To supply the 24 V power for the NT200 power supply module, external ac-
tuators and peripheral modules, external 24 V external power supply units
are available. For detailed information, refer to the price list (available w/ or-
der no. 1070 072 061).
The simplest means of connection comprises the hardware configuration wi-
thout electrical isolation between internal logic circuits and peripheral power
supply.
In this case, a power supply will be adequate to power the CL200. However,
to meet the requirements of overvoltage category II, the use of an autotrans-
former is not permitted.
