2 Safety
2.1.1 Safety Note
WARNING
The voltage of the active filter is dangerous whenever
connected to line power. 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 line power
if repair work is to be carried out. Check that the
line power supply has been disconnected and
that the necessary time has passed before
removing line power plugs.
2.
The [OFF] key on the control panel does not
disconnect the equipment from line power and is
thus not to be used as a safety switch.
3.
Correct protective grounding 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 ground leakage currents are higher than
3.5mA.
5.
Do not remove the plugs for the line power while
the filter is connected to line power supply.
Check that the line power supply has been
disconnected and that the necessary time has
passed before removing line power plugs.
6.
Please note that the filter has voltage inputs
other than L1, L2 and L3, when external 24V DC
have been installed. Make sure 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 9843 ft [3 km], 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 line power.
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 ground leakage current from the filter exceeds 3.5mA.
According to IEC 61800-5-1 a reinforced protective ground
connection must be ensured by means of an PE wire -
with the same cable cross-section as the line power wiring
- must be terminated separately.
Residual Current Device
This product can cause DC 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
grounding of the filter and the use of RCDs must always
follow national and local regulations.
2.1.3 Before Commencing Repair Work
WARNING
Hazardous Voltage!
1.
Disconnect the filter from line power
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.
