Technical data
Input power connections
WARNING!
Do not operate the drive outside the nominal input line voltage range.
Overvoltage can result in permanent damage to the drive.
Input power specifications
Disconnecting device for isolation
Install a hand-operated input 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.
•
Europe
: 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.
•
Other regions
: The disconnecting device must conform to the applicable safety
regulations.
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.
The rated fuse currents given in the tables are the maximums for the
mentioned fuse types.
If smaller fuse ratings are used, check that the fuse rms
current rating is larger than the input current.
