54 Planning the electrical installation
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:
• switch-disconnector of utilization category AC-23B (EN 60947-3)
• disconnector that has 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)
• circuit breaker suitable for isolation in accordance with EN 60947-2.
Other regions
The disconnecting device must conform to the applicable safety regulations.
Selecting and dimensioning the main contactor
If a main contactor is used, its utilization category (number of operations under load)
must be AC-1 according to IEC 60947-4,
Low-voltage switchgear and controlgear
.
Dimension the main contactor according to the nominal voltage and current of the
drive.
Checking the compatibility of the motor and drive
Use an asynchronous AC induction motor, permanent magnet synchronous motor or
AC induction servomotor with the drive. Several induction motors can be connected
to the drive at a time.
Select the motor size and drive type from to the rating tables in chapter
on basis of the AC line voltage and motor load. Use the DriveSize PC tool if you
need to tune the selection more in detail.
Ensure that the motor withstands the maximum peak voltage in the motor terminals.
See the
. For basics of protecting the motor insulation
and bearings in drive systems, refer to section
Protecting the motor insulation and
below.
Note:
• Consult the motor manufacturer before using a motor whose nominal voltage
differs from the AC line voltage connected to the drive input.
• The voltage peaks at the motor terminals are relative to the supply voltage of the
drive, not the drive output voltage.
• If the motor and drive are not of the same size, consider the following operation
limits of the drive control program:
•
motor nominal voltage range 1/6 ... 2 ·
U
N
•
motor nominal current range 1/6 ... 2 ·
I
N
of the drive in DTC control and
0 ... 2 ·
I
N
in scalar control. The control mode is selected by a drive parameter.
