*2 Use a magnetic contactor with an operation delay time (interval between current being applied to the coil until closure of contacts) of 80
ms or less. Bus voltage may drop depending on the main circuit voltage and operation pattern, causing a dynamic brake deceleration
during a forced stop deceleration. If dynamic brake deceleration is not required, delay the time to turn off the magnetic contactor.
*3 Operating the on switch and off switch with the DC power supply meets IEC/EN 60204-1 requirements.
*4 Do not share the 24 V DC power supply for interface with a magnetic contactor. Always use the power supply designed exclusively for
the magnetic contactor.
*5 If wires used for L11 and L21 are thinner than wires used for L1 and L3, use a fuse.
