1) Common installation rules and safety information regarding EURA E2000+ inverters
Electrical wiring of frequency inverters
The entire plant must be disconnected from power, crosschecked for
DANGER HAZARDOUS loss of voltage and locked before starting any work
CAPACITOR CHARGE
LVD
– DOUBLE
INSULATON
The discharge time of the internal DC-LINK
capacitors may take up to 5 minutes, it is not allowed
to open the enclosures or to do any maintenance
work during discharge cycle!!
All connection terminals for control and feed-back are single insulated
in sense of EN50178.
In case of connection to external equipment with double insulation,
the user has to provide proper arrangement, to guarantee double
insulation in sense of EN50178 for the whole system
E2000+ inverters are designed for steady state installation, using
GROUNDING
fixed wiring. It is not allowed, to use power plug or similar mobile
connection.
Depending on different EMC filter arrangements, the leakage
current to ground may exceed 3,5 mA. Therefore it is recommended
to use earth connection wiring, with minimum section of 10mm
2
(copper) or use double wiring (in sense of EN50178)
All grounding connections must be as short as possible, all leading to
one common central point (star arrangement).
Long motor leads
A motor cable lenght, exceeding 30m , may result in over-voltage
spikes on the motor side. These peaks may damage the internal
insulation of the motor.
The use of motor chokes, sinus filter or dV/dt limiting filters may
prevent from risk of motor damage.
Generally it is recommended, to use inverter duty motors In
case of any doubt, please contact the manufacturer
All output filter components must have
inverter manufactures approval
