To minimize EMI generation, you should connect a suppression network: for 120V AC, use Allen-Bradley
cat. no. 700-N24; for 220/240V AC, use cat. no. 599-KA04.
To minimize EMI generation, you should connect a suppression network: for 120V AC, use Allen-Bradley
cat. no. 599-K04; for 220/240V AC, use cat. no. 599-KA04.
For a power supply with a groundable chassis, this represents connection to the chassis only. For a power supply
without a groundable chassis, this represents connection to both the chassis and the GND terminal.
In many applications, a second transformer provides power to the input circuits and power supplies for isolation from the
output circuits.

Reference the current NEC code and ANSI B151.1 for additional wiring guidelines.
To minimize EMI generation, suppression networks should be connected across coils of electromagnetic devices.
