Frequency inverter M-Max - Moeller

Installation04/10 MN04020001Z-ENConnection on control sectionThe control signal terminals are arranged under the frontal coverflap.Figure 36:Example for a single-side connection (PES) to thefrequency inverterL1 L2/N L3 U/T1 V/T2 W/T3On the other end of the control line, you should prevent anyunraveling with a rubber grommet. The shielding braid is not tomake any connection with protective ground here because thiswould cause problems with an interference loop.Figure 34:Position of control signal terminals+ 10V AI1 GND 24V DI1 DI21 2 3 6 8 9The cable hold down clamps contained in the scope of delivery canbe mounted on the cable clamp plate of the power section.The control lines should be shielded and twisted. The shielding isexposed on one side (PES), on the cable hold down clamps on thefrequency inverter for instance.4K7R11MFWDMREVPrevent the shielding from becoming unbraided, i.e. by pushingthe separated plastic covering over the end of the shielding or witha rubber grommet on the end of the shielding.Figure 37:Example for an insulated end of the control cable150.59’’PESFigure 35:Prevent the shield from becoming unbraidedAs an alternative, in addition to a broad area cable clip, you canalso twist the shielding braid at the end and connect to protectiveground with a cable clip. To prevent EMC disturbance, this twistedshielding connection should be made as short as possible (seefigure 32 on page 39.).42
