7 Electrical installation
WARNING
The electrical installation must be carried out by qualified electricians according to the
general and regional safety and installation directives.
The documentation and device specification must be complied with during installation.
Before any assembly or connection work, discharge the frequency inverter. Verify safe
isolation from power supply.
When the frequency inverter is disconnected from power supply, the mains, DC-link
voltage and motor terminals may still be live for some time. Work on the device may
only be started once the DC link capacitors have discharged. The time to wait is at least
3 minutes in the case of sizes 1 through 7.
Do not connect inappropriate voltage sources. The nominal voltage of the frequency
inverter must correspond to the supply voltage.
The frequency inverter must be connected to ground potential.
Do not remove any covers of the frequency inverter while power supply is on.
The connecting cables must be protected externally, considering the maximum voltage and current
values of the fuses. The mains fuses and cable cross-sections are to be selected according to
EN 602041 and DIN VDE 0298 Part 4 for the nominal operating point of the frequency inverter.
According to UL/CSA, the frequency inverter is suitable for operation at a supply network of a
maximum of 480 VAC which delivers a maximum symmetrical current of 5000 A (effective value) if
protected by fuses of class RK5. Only use copper cables with a temperature range of 60 / 75 °C.
The frequency inverters are to be grounded properly, i.e. large connection area and with good
conductivity. The leakage current of the frequency inverters may exceed AC 3.5 mA or DC 10 mA.
According to EN 61800-5-1 a permanent connection must be provided. The protective conductor
cross-section required for grounding the fixing plate must be selected according to the size of the unit.
In these applications, the cross-section must correspond to the recommended cross-section of the
wire.
CAUTION
IP20 ingress protection rating is only achieved with terminals plugged and properly
mounted covers.
Special connection variants are possible apart from the standard connection variant described in these
Operating Instructions:
 Parallel connection (see "Application Manual – Parallel Connection")
 DC supply (if you have any questions on this, contact BONFIGLIOLI Customer Service.)
Connection Conditions
 The frequency inverter is suited for connection to the public or industrial supply mains according
to the technical data. If the transformer output of the supply mains is ≤ 500 kVA, a mains
commutation choke is only necessary for the frequency inverters identified in the technical data.
The other frequency inverters are suitable for connection without a mains commutating choke
with a relative mains impedance
 1%.
 Check, based on the specifications of EN 61000-3-2, if the devices can be connected to the public
supply means without taking additional measures. The frequency inverters ≤ 9.2 kW with
integrated EMC filter comply with the emission limits of the product standard EN 61800-3 up to a
motor cable length of 10 m, without additional measures being required. Increased requirements
in connection with the specific application of the frequency inverter are to be met by means of
optional components. Commutating chokes and EMC filters are optionally available for the series
of devices.
