Safety Regulations; Warning Against Unintended Start - Danfoss VLT 8000 AQUA series Operating Instructions Manual

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, serious
personal injury or death.
Consequently, the instructions in this manual,
as well as national and local rules and safety
regulations, must be complied with.

Safety regulations

1. The frequency converter must be disconnected
from the 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 [OFF/STOP] key on the control panel 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/grounding 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 the National Electrical Code and local codes.
4. The earth leakage currents are higher than 3.5mA.
5. Protection against motor overload is not included in
the factory setting. If this function is required, set
parameter 117, Motor thermal protection, to data
value ETR trip or data value ETR warning.
Note: The function is initialised at 1.0 x rated motor
current and rated motor frequency (see parameter
Touching the electrical parts may be fatal - even after the equipment has
been disconnected from line.

protection in accordance with the 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, L3 when the DC-bus
terminals or AUX 24 V option are used.
Check that all voltage inputs have been
disconnected and that the necessary time has
passed before repair work is commenced.

Warning against unintended start

1. The motor can be brought to a stop by means
of digital commands, bus commands, references
or a local stop, while the frequency converter
is connected to mains. If personal safety
considerations make it necessary to ensure
that no unintended start occurs, these stop
functions are not sufficient.
2. While parameters are being changed, the motor
may start. Consequently, the stop key [OFF/
STOP] must always be activated, following
which data can be modified.
3. A stopped motor may start if a fault occurs in
the electronics of the frequency converter, or
if a temporary overload or a fault in the supply
mains or the motor connection ceases.
