Technical data
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.
Input power specifications
Branch circuit protection
The ACH550 does not include a disconnect device. A means to disconnect input
power must be installed between the AC power source and the ACH550. This
branch circuit protection 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
The following tables provide fuse recommendations for short circuit protection on the
drive’s input power. These recommendations are not requirements if branch circuit
protection is otherwise provided per NEC. UL508A manufacturers are not required to
use the recommended fuses for the purpose of UL listing a panel that includes the
ACH550.
Fuses with higher current rating than the recommended current rating must not be
used. Fuses of the same class with lower current rating may be used.
