Work on electric components may only be carried out by trained electricians or by persons instructedin electricity under the supervision of an electrician in accordance with electrical engineering regula-tions.A second person must always be present when working on energized parts or lines who disconnectsin case of emergency.Inspect electrical equipment periodically: retighten loose connections – immediately replace damagedlines and cables.Always keep switch cabinets and all electrical supply facilities locked. Access is only allowed forauthorized persons using a key or special tool.Never clean electrical equipment with water or similar liquids.5.1 EMC-compatible installationWhen correctly installed (see below), the frequency inverter corresponds to the following standards:• EN 12015:2004 Electromagnetic compatibility – Product family standard for lifts, escalators andmoving walks – Emission• EN 12016:2004 + A1:2008 Electromagnetic compatibility – Product family standard for lifts, escala-tors and moving walks – ImmunityThe following points must be observed if the above mentioned standards are to be adhered to:• Use only shielded cables for motor and brake chopper or brake resistor connections• Max. motor line length is 25 m• Wind unshielded cables of brake resistor type BR11-A around the toroidal core provided (seefigure)• If you must interrupt the shielding on a cable (e.g., to install a motor contactor), the shielding mustbe subsequently continued with the lowest possible HF impedance.• Use only shielded control cables• The shielding of power cables (motor cable, Brake-Chopper cable) must be connected to groundon both sides• The shielding of control cables (inputs and outputs, rotary encoder cable, etc.) must be connectedto earth potential on the inverter side• Use shielded lines in the switching cabinet also• Do not twist shielding for connections; use a suitable shield connection system• Run the control cables and the encoder cables separate from the power cables• Provide connected inductances (brakes, motor contactors) with suppressors• Feed the power supply of the motor contactors through the mains filter of the lift controlInformationPlease contact the manufacturer for information on adhering to the limit value class B in accordancewith EN 55011.Toroidal core BR11-ATranslation of the original operating instructionsZETADYN 4C Electrical installationR-TBA12_01-GB 1415 Part.-No. 00163371-GB16/204
