Input Power Connections

Warning! Do not operate the drive outside the nominal input line voltage
range. Over-voltage can result in permanent damage to the drive.

Disconnect Device

The ACS550 does not include a disconnect device. A means to disconnect input
power must be installed between the AC power source and the ACS550. This
disconnect device must:
• Be sized to conform to applicable safety regulations, including, but not limited to,
both national and local electrical codes.
• Be locked in the open position during installation and maintenance work.
The disconnect device must not be used to control the motor. Instead use the control
panel, or commands to the I/O terminals for motor control.

Fuses

Branch circuit protection must be provided by the end-user, and sized per national
and local electric codes. The following tables provide fuse recommendations for
short circuit protection on the drive's input power.
