4.2.2 Connecting with Power Supply
Connect a general-purpose 24VDC stabilized power supply or PD25 power supply unit to the control unit.
(1) When using general-purpose 24VDC stabilized power supply
(Note 1) Rush current may occur to lead welding on the contacts, when a magnetic switch such as relay directly
controls 24VDC's ON/OFF during 24V power supply to the control unit. Use relay with large heat
capacity of contacts to control 24VDC's ON/OFF.
(Note 2) Make a short-circuit between 0V and FG on the terminal to cut noise.
