36 Planning the electrical installation
Selecting the supply disconnecting device (disconnecting
means)
Install a hand-operated supply disconnecting device (disconnecting means) between
the AC power source and the drive. The disconnecting device must be of a type that
can be locked to the open position for installation and maintenance work.
European union
To meet the European Union Directives, according to standard EN 60204-1, Safety of
Machinery, the disconnecting device must be one of the following types:
• a switch-disconnector of utilization category AC-23B (EN 60947-3)
• a disconnector having an auxiliary contact that in all cases causes switching
devices to break the load circuit before the opening of the main contacts of the
disconnector (EN 60947-3)
• a circuit breaker suitable for isolation in accordance with EN 60947-2.
North America
The ACS320 drive does not include a disconnect device. A means to disconnect
input power must be installed between the AC power source and the ACS320 drive.
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 an 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.
Other regions
The disconnecting device must conform to the applicable safety regulations.
Checking the compatibility of the motor and drive
Check that the 3-phase AC induction motor and the drive are compatible according to
the rating table in section
on page
or in section
.
The table lists the typical motor power for each drive type.
