1.2.1. Safety Note
1
The voltage of the frequency converter is dangerous whenever connected to mains.
Incorrect installation of the motor, frequency converter or fieldbus may cause dam-
age to the equipment, serious personal injury or death. Consequently, the instruc-
tions in this manual, as well as national and local rules and safety regulations, must
be complied with.
1.2.2. Safety Regulations
1. The frequency converter 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 [STOP/RESET] key on the control panel of the frequency converter does not dis-
connect the equipment from mains and is thus not to be used as a safety switch. 3.
Correct protective earthing of the equipment must be established, the user must be pro-
tected against supply voltage, and the motor must be protected against overload in
accordance with applicable national and local regulations.
3. Correct protective earthing of the equipment must be established, the user must be pro-
tected 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. 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 or data value
ETR warning. Note: The function is initialised 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.
