Danfoss VLT 5000 Series Design Guide

The voltage of the frequency converter is
dangerous whenever the equipment is
connected to mains. Incorrect installation
of the motor or the frequency converter
may cause damage to the equipment, se-
rious personal injury or death.
Consequently, the instructions in this
manual, as well as national and local rules
and safety regulations, must be complied
with.
The Protective Extra Low Voltage (PELV)
requirements stated in IEC 61800-5-1 are
not fulfilled at altitudes above 2000 m
(6562 ft.). For 200V frequency converters
the requirements are not fulfilled at alti-
tudes above 5000 m (16 404 ft.). Please
contact Danfoss Drives for further infor-
mation.
Safety regulations
1. The frequency converter must be disconnec-
ted 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 discon-
nect 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 ac-
cordance with applicable national and local
regulations.
4. The earth leakage currents are higher than
3.5 mA.
5. Protection against motor overload is not in-
cluded in the factory setting. If this function is
desired, set parameter 128 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 func-
tions provide class 20 motor overload pro-
tection in accordance with NEC.
6. Do
not remove the plugs for the motor and
main supply while the frequency converter is
connected to mains. Check that the mains
supply has been disconnected and that the
necessary time has expired before removing
motor and mains plugs.
7. Please note that the frequency converter has
more voltage inputs than L1, L2 and L3, when
loadsharing (linking of DC intermediate cir-
cuit) and external 24 V DC have been instal-
led. Check that all voltage inputs have been
disconnected and that the necessary time
has passed before repair work is com-
menced.
