1.1.2 Safety Note
The voltage of the variable speed drive is dangerous whenever connected to mains. Incorrect installation of the motor, variable speed drive
or network may cause damage to the equipment, serious personal injury or death. Consequently, the instructions in this manual, as well as
national and local rules and safety regulations, must be complied with.
1.1.3 Safety Regulations
1. The variable speed drive must be disconnected from mains if repair work is to be carried out. Check that the mains supply has been disconnected and
that the necessary time has passed before removing motor and mains plugs.
2. The off-command on the serial bus does not disconnect the equipment from mains and is thus not to be used as a safety switch.
3. Correct protective earthing or grounding of the equipment must be established, the user must be protected against supply voltage, and the motor must
be protected against overload in accordance with applicable national and local regulations.
4. The earth leakage currents are higher than 3.5 mA.
5. Do not remove the plugs for the motor and mains supply while the variable speed drive is connected to mains. Check that the mains supply has been
disconnected and that the necessary time has passed before removing motor and mains plugs.
