Wiring information for single-motor operation
• The motor phases U, V, W must be correctly connected in accordance with the motor
connection terminals in the MOVIFIT

unit. This measure ensures that the direction
of rotation of the motor in single-motor operation is correct.
7.1.2
Wiring information for dual-motor operation
• In "dual-motor operation" mode, the supply system phases L1, L2, and L3 must be
connected in accordance with the mains phase sequence at the terminals in the unit.
If you do not follow this sequence, the unit generates the error message "Startup,
no. 9, internal error 3" when the power is connected. In this case, the power section
will not be enabled.
• The motor phases U, V, W of the motors must also be connected correctly in accor-
dance with the motor connection terminals in MOVIFIT
®
at the terminals X8/X81
(motor 1) or X9/X91 (motor 2) so that the motor turns clockwise in dual-motor oper-
ation.
STOP!
Important: For operation with only one motor, use X8 and X81 terminals or the X8 plug
connector.
Do not connect the X9 and X91 terminals or the X9 plug connector.
