4 Unidrive M400 Step By Step Guide
Issue Number: 2
STEP 5: Select cables and fuses or MCB
* These fuses are fast acting.
** For UL installations, the circuit breaker must be Listed under category control number DIVQ / DIVQ7, rated
600 Vac with a short circuit rating > 10 kA. In other countries, circuit breakers compliant with EN IEC 60947-2 are
recommended, with > 10 kA short circuit breaking capacity
The voltage rating of fuses and MCBs must be greater than or equal to the highest supply voltage of
the system. Fuses: The AC supply to the drive must be installed with suitable protection against
overload. Failure to observe this requirement will cause risk of fire.
Ground conductor size:- Either 10 mm
2
or two conductors of the same cross-sectional area as the input
conductors.

The product is UL listed for use on a circuit up to 100 kA maximum supply symmetrical fault current,
when protected by fuses.
IEC cable sizes assume Copper conductor, PVC insulation, Installation method B2 and ambient
temperature of 40 °C (104 °F). UL cable sizes assume Copper conductor with insulation rated at 75 °C
(167 °F).
