guidelines for making user connections.
Wiring
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.
In ACS880-07CLC/07LC/17LC/37LC drives, one emergency stop button is installed on the
cabinet door. This is the case also in ACS880 multidrives ordered with option +G331. The
button is connected with a one-channel connection to the emergency stop safety relay [A61]
or [A640] at the factory. User-made connections to this circuit are not necessary. You must
not install additional emergency stop buttons in series with the emergency stop button.
If 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.
Connecting the user-defined push buttons
￭
Obey the rules below:
• Use buttons that are suitable for the application.
• Use shielded, twisted-pair cable. ABB recommends gold-plated contacts in the buttons.
