• Supply 24 VDC.
• Use the Power Supply Unit of the voltage shown in the table below.
DC Power Supplies
When you connect a computer or other peripheral device to a Controller that has a non-isolated
DC Power Supply Unit NX-PD7001, either ground the 0-V side of the external power supply or
do not ground it at all.
If the peripheral devices are grounded incorrectly, the external power supply may be short-cir-
cuited. Never ground the 24-V side of the power supply, as shown in the following figure.
