Mechanical installation 31 Mechanical installation Contents of this chapter This chapter describes the mechanical installation of the brake units. Brake unit The ACS880 multidrive - the brake unit as one part of the complete drive - is transported in sections. Refer to ACS880 multidrive cabinets mechanical installation instructions (3AUA0000101764 [English]).
Limitation of liability The installation must always be designed and made according to applicable local laws and regulations. ABB does not assume any liability whatsoever for any installation which breaches the local laws and/or other regulations. Furthermore, if the recommendations given by ABB are not followed, the drive may experience problems that the warranty does not cover.
34 Guidelines for planning the electrical installation • Each output of the brake chopper module must feed a resistor of its own. There are 3 outputs in the 3-phase brake chopper module. The resistance ( R ) of the brake resistor must be equal to or above the value •...
Guidelines for planning the electrical installation 35 Selecting the resistor thermal switch cable Make sure that the cable in the resistor thermal switch circuit meets the following requirements: • shielded cable • rated operating voltage between a core and ground > 750 ( U •...
This chapter contains instructions on wiring the brake units. If the brake resistors are included as factory-installed (option +D151), and placed in the same cabinet line-up with the brake chopper, the electrical installations are done by ABB at the factory.
38 Electrical installation Electrical safety precautions These electrical safety precautions are for all persons who do work on the drive, motor cable or motor. This procedure gives information on how to de-energize the drive and make it safe to do work on it. The procedure does not include all possible drive configurations. Each drive is made to order.
Electrical installation 39 • Make sure that the voltage between the output power terminals of the drive (U, V, W) and the grounding (PE) busbar is zero. Important! Repeat the measurement with the DC voltage setting of the voltage tester. Measure between each phase and ground. There is a risk of dangerous DC voltage charging due to leakage capacitances of the motor circuit.
Page 40
40 Electrical installation Stop the drive and do the steps in section Electrical safety precautions (page 38) before you start the work. Make sure that the resistor cable is connected to the resistor and disconnected from the drive output terminals. At the drive end, connect the R+ and R- conductors of the resistor cable together.

42 Electrical installation The diagram also shows the internal connections of the brake chopper module cubicle done by ABB. Connection procedure of the resistor cables ■ WARNING Obey the safety instructions of the drive. If you ignore them, injury or death, or damage to the equipment can occur. If you are not a qualified electrical professional, do not do installation, commissioning, or maintenance work.
Electrical installation 43 Connection procedure of the thermal switch cable ■ WARNING Obey the safety instructions of the drive. If you ignore them, injury or death, or damage to the equipment can occur. If you are not a qualified electrical professional, do not do installation, commissioning, or maintenance work.
44 Electrical installation Strip the ends of the conductors. Try to keep the unshielded portion of the conductors as short as possible. Use tape or shrink tubing to contain any stray strands. Connect the conductors to the appropriate terminals. Twist the shields into a bundle, crimp a ring terminal onto it and connect it to the nearest chassis grounding point.
Electrical installation 45 Connecting a PC NOTICE Do not connect a PC directly to the control panel connector of the control unit. It can cause damage. To connect a control panel to a PC (with, for example, Drive Composer PC tool): Put the control panel into the panel holder or platform.
