given in the table below without exception.
1.6 - UL conformity
1.6.1 Specified mains supply
The drive can be incorporated in an installation with short circuit capacity of 5000 A rms maximum at voltage 264 VAC rms
maximum for 230 V (TL) drives or 528 VAC rms maximum for 400 V (T) drives.
1.6.2 Cables
Only class 1 copper cables 60/70° C (140/167° F) should be used.
1.6.3 Fuses
UL conformity is adhered to if the fuses are UL-listed, fast-blow fuses (class CC up to 30 A) with a rating as indicated in
the above table and if the short-circuit symmetrical current does not exceed 5 kA.
1.4 - Radio-frequency interference:
1.4.1 - General
Variable speed drives use high-speed switches (transistors,
semi-conductors) which switch high voltages (around 660V
for 3-phase drives) at high frequencies (several kHz). This
provides better efficiency and a low level of motor noise. As
a result, they generate radio-frequency signals which may
disturb operation of other equipment or distort measurements
taken by sensors:

or the drive/motor cable: radiated emissions
These phenomena are of direct interest to the user. The
frequency range concerned (radio-frequency) does not affect
the energy distribution company.
1.4.2 - Standards (Emission)
The maximum emission level is set by (EN 50081-2) and
(EN 50081-1). IntelliGear Plus conforms to:
•EN50081-2asstandard
•EN50081-1withlteroption
1.4.3 - Standards (Immunity)
The maximum immunity level is set by (EN 50082-2) and
(EN 50082-1). IntelliGear Plus conforms to:
•EN50082-2andEN50082-1asstandard
