If operating with a three-phase 220/230 V power supply without neutral, a connection jumper must be made between terminals
L3 and N of MR.
If operating with TMF, it is necessary to remove the connection jumper between terminals 1 and 4 of the MR terminal board.
When operating with CONTINUOUS MODULATION using a LANDIS RWF 40 regulator, remove the connection jumper between
terminal 9 - 7 of MR.
N.B. The connection from probe S to terminal G of MRM is required only with the pressure probe (LANDIS QBE...)
DO not exchange the neutral with the phase wire. Make proper earth connections..
COMPLY WITH GOOD ENGINEERING PRACTICES AND OBSERVE THE REGULATIONS IN FORCE.
