[2] Wiring and setting of safety circuit
(1) Power supply
To use safety relays and/or contactors of 24V DC specification in the safety circuit, the
control power supply should be used only for the circuit as much as possible. (Do not use the
same power source as the driving power supply for this controller.)
It is the risk prevention treatment preparing for the cases such as the operation error of the
safety circuit caused by not enough power capacity.
