If operating with a three-phase 230/240 V power supply without neutral, a connection jumper must be made between
terminals L3 and N of the MR transmission terminal board as well as a delta connection in the MB motor.
If operating with TMF, it is necessary to remove the connection jumper between terminals 1 and 2 of the MR transmission
terminal board.
Do not exchange the neutral with the phase wire.
Make the connection to an efficient earthing system.
COMPLY WITH GOOD ENGINEERING PRACTICES AND OBSERVE THE REGULATIONS IN FORCE.
