servicing the adjustable frequency drive, wait the minimum amount of time indicated below:
Voltage Power Waiting Time
200–240 V 0.34–5 hp [0.25–3.7 kW] 4 minutes
7.5–50 hp [5.5–37 kW] 15 minutes
380–480/500 V 0.5–10 hp [0.37–7.5 kW] 4 minutes
15–100 hp [11–75 kW] 15 minutes
525–600 V 1–10 hp [0.75–7.5 kW] 4 minutes
15–100 hp [11–75 kW] 15 minutes
525–690 V 15–100 hp [11–75 kW] 15 minutes
2.1.1 High Voltage
The voltage of the adjustable frequency drive is dangerous whenever the adjustable frequency drive is connected to line power.
Incorrect installation or operation of the motor or adjustable frequency drive may cause damage to the equipment, serious personal
injury or death. The instructions in this manual must therefore be observed, in addition to applicable local and national rules and safety
regulations.
Installation at high altitudes
380–500 V: At altitudes above 9,843 feet [3 km], please contact Danfoss regarding PELV.
525–690 V: At altitudes above 6,600 feet [2 km], please contact Danfoss regarding PELV.
2.1.2 Safety Precautions
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 may cause death, serious personal injury or damage to the equipment. Con-
sequently, the instructions in this manual, as well as national and local rules and safety regulations, must be complied with.
Safety Regulations
1. The line power supply to the adjustable frequency drive must be disconnected whenever repair work is to be carried out. Make sure that the
line power supply has been disconnected and that the necessary time has elapsed before removing motor and line power supply plugs.
2. The [OFF] button on the control panel of the adjustable frequency driver does not disconnect the line power supply and consequently it must
not be used as a safety switch.
3. The equipment must be properly grounded, 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 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
Motor Thermal Protection to
data value ETR trip 1 [4] or data value ETR warning 1 [3].
