• All connection work must be performed in
accordance with the laws in force in the country in
which the drive is installed. This includes earthing to
ensure that no directly accessible part of the drive can be
at the mains voltage or any other voltage which may be
dangerous, a source of serious injury, malfunctions or
electromagnetic interference.
• The voltages on the cables or connections of the
mains supply, the motor or the filter may cause fatal
electric shocks. Contact with these items must be avoided
under all circumstances.
• The drive must be supplied via a circuit-breaking
device so that it can be powered down safety.
• The drive power supply must be protected against
overloads and short-circuits.
• The drive stop function does not protect against
high voltages on the terminal blocks.
• Check that the voltage and current of the drive, the
motor and the mains supply are compatible.
• After the drive has been operating, keep away from
the heatsink as it may be very hot (+70°C).
• When the drive controls a permanent magnet
motor, only one motor can be connected to the drive output.
It is advisable to install a circuit-breaking device between
the permanent magnet synchronous motor and the drive
output. This breaker isolates the motor during maintenance
work on the drive.
