How to operate the Pentruder MDU9 Drive Unit - NTGRA

®

WARNING!

All the safety instructions in chapter 3 must be taken into account and followed.

Note!

The Power and Motor LED’s will help the operator to use the machine efficiently. Consult the
MDU Drive Unit Indication chart on page 38.

5.2.1

Connect to input power

The Pentruder MDU9 Drive Unit - NTGRA

®

can be connected to both 1-phase and 3-phase

power. The European and USA version of the MDU9 Drive Unit can operate in this voltage range:
AC 50Hz – 440 Hz from 200V to 480V.

a.

To connect to 230 – 250 Volt 1-phase power input, use the adapter cable seen above.

b.

The motor will recognize what power it is connected to with one green flash on both LED’s
and 4 short beeps.

c.

Then, the P- and M-LED’s will be blinking alternatively green for 230 – 250V
1-phase supply power and blue for 400-480V 3-phase supply power. This indicates that the
input power is ok and that the motor is waiting for the start key to be inserted.

See MDU9 Drive Unit Indication chart on page 38
