AC Motor
• The required supply voltage is 230 Volt - 50 Hz.
• Extension cables up to 25 m in length must have a cross
section of 1.5 mm2; extension cables which exceed 25
m in length must have a cross section of 2.5 mm2.
• The mains connection has a 16 A time delay fuse.
Three-Phase Current Motor
The 400 V / 50 Hz electric motor is designed for the S6 / 40 %
operating mode.
• The required supply voltage is 400 Volt - 50 Hz.
• The mains connection and extension cable must be
equipped with 5 wires = 3 P + N + PE.
• Extension cables must have a cross section of no less
than 1.5 mm2.
• The mains connection is fused to a maximum of 16 A.
• Check the rotational direction when connecting to the
power supply or changing location: it may be necessary
to change the polarity (wall socket).
If you have questions always provide the following information:
• motor manufacturer
• type of current used by motor
• data listed on the machine type plate
If you return the motor always send the complete drive unit
including switch.
