High Voltage Warning
WARNING
The voltage of the frequency converter and the MCO 101 option card is dangerous whenever it is connected to mains.
Incorrect installation of the motor or frequency converter could result indeath, serious injury or damage to the equip-
ment. Consequently, 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 frequency converter is dangerous whenever connected to mains. Incorrect installation of the motor,
frequency converter or fieldbus could result in death, serious personal injury or damage to the equipment. Conse-
quently, 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 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 keypad of the frequency converter does not disconnect 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 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. 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 mains supply while the frequency converter 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.
7. Please note that the frequency converter has more voltage inputs than L1, L2 and L3, when load sharing
(linking of DC intermediate circuit) and external 24 Vdc have been installed. Check that all voltage inputs
have been disconnected and that the necessary time has passed before commencing repair work.
