1) Common installation rules and safety information regarding EURA E2000+ inverters
EMC: Basics and recommendations for installation
The E2000+ series inverters are electrical devices, designed for installation in industrial area.
E2000+ inverters are not designed to work stand alone, these inverters are considered as part of
a complex system, for this reason, no separate EMC marking is applied on the inverter.
The machine builder / system integrator is obligated to prove the compliance with actual EMC
standards for the whole system.
Normally, the inverter integrated EMC filters are sufficient, to meet the actual EMC limits (this has
been confirmed by measurements, performed by independent body).
Inverters E2000+ are designed for use in "second environment", (in sense of EN61800-3).
This means installation in industrial area, where power supply is done via separate
transformer.
Fore installation in "first environment" (residential area
– public low voltage power
grid), additional filter components may become necessary, to meet EMC rules.
EMC - adequate installation
Mounting in metal cabinet, if possible, the cabinet should be divided into power and control area,
using metal shielding barrier, or similar
Connect all metal parts, grounding cables, cable shields on one central point, using the blank
mounting plate as contact area.
Use 10mm
2
cables for potential equalization, "star" connected on one central point.
Please consider, that inverters and filters may have more than 3,5 mA leakage current, therefore
use proper earth/ground conductors:
Grounding conductor min. 10 mm² (copper)
Grounding connection with separate monitoring system, which
disconnects automatically in case of fault.
Dual grounding, using separate cable and terminals.
Use shielded cables, wherever possible, with copper mesh, common cable steel protection is
not working as shield.
Connect shields on large blank areas with potential equalization bars. Use special cable glands,
with integrated contact brushes.
It is not allowed to extend cable shield, using single wire.
Mount all external filter components as close as possible to the noise source (inverter)
– get
perfect contact, mounting directly on the blank cabinet plate.
Keep all wiring as short as possible, separate different networks, min. 15 cm distance.
Different networks are: power supply, motor cable (incl. brake resistor), low voltage control wiring
(control signals, feed back, data line).
Twist all unshielded cables
Unused wires in cables should be connected to ground
