2.7.2 Motor cable (U, V, W, earth)
The motor cable may have a total length of up to 100m if this is a standard cable. If a screened motor
cable is used, or if the cable is laid in a well earthed metal conduit, the total length should not exceed
20m. In order to comply with interference suppression class C2, a total length of 5m must not be
exceeded.
Note: Please also note Section 9.4 EMC limit
value classes.
Note: For multiple motor use the total cable length
consists of the sum of the individual cable
lengths.
Note: The motor cable must not be switched as
long as the inverter is providing power to the
motor. (The inverter must be on "Standby"
or "Starting Disabled")

2.7.3 Brake resistor connection (-B, +B)
Terminals +B/ -B are intended for the connection of a suitable braking resistor. The connection should be as
short as possible.
Note: The large amount of heat produced by the
brake resistor must be taken into account.
