The Repair switch allows the motor to be totally isolated from the Inverter. This means that
all power to the motor is terminated and the Inverter cannot start or stop the motor.

The motor must be stopped before activating the Repair switch. If the motor is not stopped
the Inverter may be damaged.
Discharge of Inverter
Wait at least five minutes to allow the unit to discharge after switching the Repair switch off
before carrying out any maintenance work.
Electrical safety
Regional installation and Safety Regulations regarding work on dangerous voltage
installation (e.g. EN50178) as well as relevant regulations regarding the correct use of tools
and personal equipment ( PPE ) still apply.
