5 Electrical installationThe safety instructions described in chapter "Electrical installation" of the operating instruc-tions R-TBA12_01 (ZAdyn4C) must be observed!5.1 EMC-compatible installationWhen correctly installed (see below), the device corresponds to the following standards:• EN 12015 Electromagnetic compatibility – product series standard for lifts, escalators, movingpavements – spurious emission• EN 12016 Electromagnetic compatibility – product series standard for lifts, escalators, movingpavements – interference 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 resister connections.• Max. motor line length is 25 m• Wind unshielded cables of brake resistor type BR11-A around the toroidal core provided (seefigure)• If an interruption in the shield is necessary, the shield must then be continued with as low an HFimpedance as possible• Use only shielded control cables• The shielding of control cables (inputs and outputs, rotary encoder cable, etc.) must be connectedto earth potential on the inverter side• 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 voltage supply of the motor contactors through the mains filter of the elevator controlToroidal core BR11-A5.1.1 ZAdyn4C MRL AI5.1.1.1 Motor cableCable lengthThe maximum line length is 25 m.When lines over > 25 m are used, compliance with DIN EN 12015 (electromagnetic compatibility –electrical interference) and DIN EN 12016 (electromagnetic compatibility – noise immunity) is nolonger guaranteed.Contacting the shielding of the motor line on the ZAdyn4C MRL AIOn the ZAdyn4C MRL AI, the shielding of the motor line must be connected with earth potential withthe clip provided (see fig.).Original operating instructionsZAdyn4C MRL Electrical installationR-TBA14_01-GB 1845 Part.-No. 00163419-GB8/44
