Type of motor cable
Refer also to
Wiring recommendations
later in this chapter.
Routine EMC precautions
Use either of the following:
•
Cable containing three power conductors plus a ground conductor
•
Three separate power conductors plus a ground conductor
Compliance with EMC emissions standards
Use shielded (screened) or steel-wire armoured cable having three power
conductors plus an optional ground conductor.
Interruption in the motor cable
If the cable between the Drive and motor is to be interrupted by a
contactor or circuit breaker, ensure the Drive is disabled before the
contactor or circuit breaker is opened or closed.
Fuses
Warning
The
AC
supply to the Drive must be fitted with suitable
protection against overload and short-circuits. Table 4–2
shows recommended fuse ratings. Failure to observe this
recommendation will cause a risk of fire.
When a single-phase supply is used, a fuse of the specified rating should be
included in the live connection of the
AC
supply. When two phases of a
three-phase are used, a fuse of the specified rating should be included in
both phases of the
AC
supply.
