2.1.1 Safety Note
WARNING
The voltage of the Active Filter is dangerous whenever
connected to mains. Incorrect installation of the filter or
options 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 Filter 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
mains plugs.
2.
The [OFF] key on the control panel 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 and the user must be
protected against supply voltage in accordance
with applicable national and local regulations.
4.
The earth leakage currents are higher than
3.5mA.
5.
Do not remove the plugs for the mains supply
while the filter is connected to mains. Check that
the mains supply has been disconnected and that
the necessary time has passed before removing
mains plugs.
6.
Please note that the filter has voltage inputs
other than L1, L2 and L3, when external 24V DC
have been installed. Check that all voltage inputs
have been disconnected and that the necessary
time has passed before commencing repair work.
Installation at high altitudes
NOTE
At altitudes above 3km, please contact Danfoss Drives
regarding PELV
2.1.2 General Warning
WARNING
Touching the electrical parts may be fatal - even after the
equipment has been disconnected from mains.
Before touching any potentially live parts of the unit, wait
at least as follows:
380 - 480 V, 190-400A, wait at least 20 minutes.
Shorter time is allowed only if indicated on the nameplate
for the specific unit. Be aware that there may be high
voltage on the DC links even when the Control Card LEDs
are turned off. A red LED is mounted on a circuit board
inside the active filter to indicate the DC bus voltages. The
red LED will stay lit until the DC link is 50V DC or lower.
CAUTION
Leakage current
The earth leakage current from the filter exceeds 3.5mA.
According to IEC 61800-5-1 a reinforced Protective Earth
connection must be ensured by means of an PE wire -
with the same cable cross section as the Mains wiring -
must be terminated separately.
Residual Current Device
This product can cause a D.C. current in the protective
conductor. Where a residual current device (RCD) is used
for extra protection, only an RCD of Type B (time delayed)
shall be used on the supply side of this product. Protective
earthing of the filter and the use of RCD's must always
follow national and local regulations.
2.1.3 Before Commencing Repair Work
WARNING
Hazardous Voltage!
1.
Disconnect the filter from mains
2.
Wait at least the amount of time indicated in
section General Warning above
Failure to follow recommendations could result in death or
serious injury.
2.1.4 Special Conditions
Electrical ratings:
The rating indicated on the nameplate of the active filter is
based on a typical 3-phase mains power supply, within the
specified voltage, current and temperature range, which is
expected to be used in most applications.
