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")

Connection cross-section:

Size 1 … 3:

0.5 ... 6mm

rigid/flexible cable AWG 20-10

Size 4:

0.5 ... 16mm

rigid/ flexible cable AWG 20-6

Tightening torque:

1.2 ... 1.5Nm

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.
