WARNING!
Obey the safety instructions of the drive. If you ignore them, injury or death,
or damage to the equipment can occur. If you are not a qualified electrical
professional, do not do installation or maintenance work.
One emergency stop button is installed on the cabinet door and connected to the emergency
stop safety relay [A640] at the factory. There are double contacts in the emergency stop
button and double wiring (two-channel connection) between the button and the emergency
stop safety relay. The emergency stop safety relay [A640] detects cross faults and faults
across one contact from the emergency stop button.
The drive does not have a factory-installed main contactor/breaker. You must install one
and connect its control circuit and status monitoring circuit to the drive. Refer to the drive
hardware manual and the circuit diagrams delivered with the drive.
Note: The safety system and all user-made connections are on the user's responsibility.
