The factory setting is for clockwise rotation with the VLT frequency converter output connected

as follows:

Terminal No.

Function

96, 97, 98,

Mains U/T1, V/T2, W/T3

Ground/Earth

•Terminal U/T1/96 connected to U-phase

• Terminal V/T2/97 connected to V-phase

• Terminal W/T3/98 connected to W-phase

The direction of rotation can be changed by switching two phases in the motor cable.

3.2.9. Brake Cable

(Only standard with brake and extended with brake. Typecode: SB, EB, DE, PB).

Terminal No.

Function

81, 82 Brake resistor terminals

The connection cable to the brake resistor must be screened. Connect the screen by means of

cable clamps to the conductive back plate at the frequency converter and to the metal cabinet of

the brake resistor.

Size the brake cable cross-section to match the brake torque. See also Brake instructions, MI.

90.FX.YY and MI.50.SX.YY for further information regarding safe installation.

Please note that voltages up to 1099 V DC, depending on the supply voltage, may

occur on the terminals.

3.2.10. Brake Resistor Temperature Switch

Torque: 0.5-0.6 Nm (5 in-lbs)

Screw size: M3

This input can be used to monitor the temperature of an externally connected brake resistor. If

the input between 104 and 106 opens, the frequency converter will trip on alarm 29. If the con-

nection is closed between 104 and 105, the frequency converter will trip on alarm 29.

Normally closed: 104-106 (factory installed jumper)

Normally open: 104-105

Terminal No.

Function

106, 104, 105 Brake resistor temperature switch.
