01/02 AWB8230-1413GB EMC <strong>com</strong>plianceThe screened cable between frequency inverter <strong>and</strong> motor shouldbe as short as possible. Connect the screen to earth at both endsof the cable using a connection with a large contact surface.Lay the cables for the supply voltage separately from the signalcables <strong>and</strong> control cables.Never unravel the screening or use pigtails to make a connection.Figure 16:Inadmissible screen grounding (pigtails)In an EMC-<strong>com</strong>pliant control cabinet (metal-enclosed, damped toabout 10 dB), the motor cables do not need to be screenedprovided that the frequency inverter <strong>and</strong> motor cables are spatiallyseparated from each other <strong>and</strong> arranged in a separate partitionfrom the other control system <strong>com</strong>ponents. The motor cablescreening must then be connected with a large surface areaconnection at the control cabinet (PES).The control cable <strong>and</strong> signal (analog setpoint <strong>and</strong> measured value)cable screens must be connected only at one cable end. The screenconnection must have a large contact surface a low impedance.Digital signal cable screens must be connected at both cable ends,also with large-surface, low-resistance connections.If contactors, maintenance switches, motor protection relays,motor chokes, filters or terminals are installed in the motorcabling, interrupt the screen near these <strong>com</strong>ponents <strong>and</strong> connectit to the mounting plate (PES) using a connection with a largecontact surface. The free, unscreened connecting cables shouldnot be longer than about 100 mm.Example: Maintenance switchaPESbPESFigure 17: Maintenance switch, e.g. T… in an enclosurea Metal plateb Insulated PE terminal25
Installation01/02 AWB8230-1413GBElectrical connectionThis section describes how to connect the motor <strong>and</strong> the supplyvoltage to the power terminals, <strong>and</strong> the signal cables to thecontrol terminals <strong>and</strong> the signalling relay.Warning!Carry out the wiring work only after the frequency inverterhas been correctly mounted <strong>and</strong> secured. Otherwise,there is a danger of electrical shock or injury.Warning!Carry out wiring work only under zero voltage conditions.Warning!Use only cables, residual-current circuit breakers <strong>and</strong>contactors with a suitable rating. Otherwise there is adanger of fire.The following illustration shows an overview of the connections.26
