NOTICE!
Signal cables must not be laid parallel to high-voltage current lines or mains cables. Lay supply and signal
lines in separate channels. An angle of 90° is required at line crossings. If signal lines are longer than 2 m,
shielded cables must be used.
ATTENTION!
To avoid premature wear of the gear, always ensure the correct rotation direction of the motor: counter-
clockwise (to the left), looking toward the fan wheel.
