Safety instructions

WARNING! All electrical installation and maintenance work on the inverter must
be carried out by qualified electricians only. Follow the safety instructions listed
below.
•
Never work on the inverter, the braking chopper circuit, the motor cable or the motor
when input power is applied to the inverter.
•
After disconnecting the input power, always wait for 5 minutes to let the intermediate
circuit capacitors discharge. Always ensure by measuring that no voltage is actually
present.
•
A rotating permanent magnet motor generates a dangerous voltage. Always ensure to
lock the motor shaft mechanically before connecting a permanent magnet motor to the
inverter, and before doing any work on an inverter system connected to a permanent
magnet motor.
