2 Safety Instructions and General Warning

The DC link capacitors remain charged after power has been disconnected. To avoid electrical shock hazard, disconnect the frequency
converter from mains before carrying out maintenance. When using a PM-motor, make sure it is disconnected. Before doing service
on the frequency converter wait at least the amount of time indicated below:
Voltage Power
200 - 240 V 0.25 - 3.7 kW
5.5 - 37 kW
380 - 480/500 V 0.37 - 7.5 kW
11 - 75 kW
525 - 600 V 0.75 - 7.5 kW
11 - 75 kW
525 - 690 V 11 - 75 kW

2.1.1 High Voltage

The voltage of the frequency converter is dangerous whenever the frequency converter is connected to mains. Incorrect installation
or operation of the motor or frequency converter may cause damage to the equipment, serious personal injury or death. The instructions
in this manual must consequently be observed, as well as applicable local and national rules and safety regulations.
Installation in high altitudes
380 - 500 V: At altitudes above 3 km, please contact Danfoss regarding PELV.
525 - 690 V: At altitudes above 2 km, please contact Danfoss regarding PELV.
2.1.2 Safety Precautions
The voltage of the frequency converter is dangerous whenever connected to mains. Incorrect installation of the motor, frequency
converter or fieldbus may cause 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.
Safety Regulations
1. The mains supply to the frequency converter must be disconnected whenever repair work is to be carried out. Check that the mains supply has
been disconnected and that the necessary time has elapsed before removing motor and mains supply plugs.
2. The [OFF] button on the control panel of the frequency converterr does not disconnect the mains supply and consequently it must not be used
as a safety switch.
3. The equipment must be properly earthed, 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 current exceeds 3.5 mA.
5. Protection against motor overload is not included in the factory setting. If this function is desired, set par. 1-90
data value ETR trip 1 [4] or data value ETR warning 1 [3].
6. Do not remove the plugs for the motor and mains supply while the frequency converter is connected to mains. Check that the mains supply has
been disconnected and that the necessary time has elapsed before removing motor and mains plugs.
