3. Installation
The factory setting is for clockwise rotation with the VLT frequency converter output connected
as follows:
Terminal No. Function
96, 97, 98,
99
3
• 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
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.
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.
