NOTE! Minimum cable length for double output without dU/dt filter is 5 meters (16.4 ft).
In FR13 units NXP1300 and NXP 1450 there are 3 NFE units.
NOTE! Minimum cable length for matched power units without dU/dt filter is 5 meters (16.4 ft). For unmatched power units, a min
of 40 m (131.2 ft) of cable length is required from each power unit if dU/dt or sine filters are not used.
NOTE! Some options affect the wiring direction and principle for power cables; always check delivery specific documentation for
exact information.
6.1.6 DC Supply and Brake Resistor Cables
VACON
®
6- and 12-pulse AC drives have terminals for the DC supply and an optional external brake resistor. These terminals are
identified with B–, B+/R+, and R–. The DC bus connection is made to terminals B– and B+ and the brake resistor connection to R+
and R–. The AC drive terminals can also optionally be wired to customer terminals in the cabinet. For additional information on
integrated brake chopper and resistor values, see the VACON
