High Voltage Warning

WARNING

The voltage of the adjustable frequency drive is dangerous whenever it is connected to line power. Incorrect installation of the motor or adjustable frequency drive could result indeath, serious injury or damage to the equipment. Conse- quently, it is essential to comply with the instructions in this manual as well as local and national rules and safety regulations.

Safety Note

WARNING

The voltage of the adjustable frequency drive is dangerous whenever connected to line power. Incorrect installation of the motor, adjustable frequency drive or serial communication bus could result in death, serious personal injury or damage to the equipment. Consequently, the instructions in this manual, as well as national and local rules and safety regulations, must be complied with.

WARNING

Failure to follow instructions below could result in death or serious injury.

Safety Regulations

1.The adjustable frequency drive must be disconnected from line power if repair work is to be carried out. Make sure that the line power supply has been disconnected and that the necessary time has passed before removing motor and line power plugs.

2.The [STOP/RESET] key on the keypad of the adjustable frequency drive does not disconnect the equipment from line power and is thus not to be used as a safety switch.

3.Correct protective 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 ground leakage currents are higher than 3.5 mA.

5.Protection against motor overload is set by par.1-90 Motor Thermal Protection. If this function is desired, set par.1-90 Motor Thermal Protection to data value [ETR trip] (default value) or data value [ETR warning]. Note: The function is initialized at 1.16 x rated motor current and rated motor frequency. For the North American market: The ETR functions provide class 20 motor overload protection in accordance with NEC.

6.Do not remove the plugs for the motor and line power supply while the adjustable frequency drive is con- nected to line power. Make sure that the line power supply has been disconnected and that the necessary time has passed before removing motor and line power plugs.

7.Please note that the adjustable frequency drive has more voltage inputs than L1, L2 and L3, when load sharing (linking of DC intermediate circuit) and external 24 Vdc have been installed. Make sure that all voltage inputs have been disconnected and that the necessary time has passed before commencing repair work.
