Mechanical installation 31 Mechanical installation Contents of this chapter This chapter describes the mechanical installation of the brake units. Brake units The ACS880 multidrive - the brake unit as one part of the complete drive - is transported in sections. See ACS880 multidrive cabinets mechanical installation instructions (3AUA0000101764 [English]).
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 • The resistance (R) of the brake resistor assembly must be equal to or above the value specified. Never use resistance values below the specified value. • The resistor must withstand the specified brake cycles. •...
Guidelines for planning the electrical installation 35 WARNING! The materials near the brake resistor must be non-flammable. The surface temperature of the resistor is high. Air flowing from the resistor is of hundreds of degrees Celsius. If the exhaust vents are connected to a ventilation system, make sure that the material withstands high temperatures.
Electrical installation 37 Electrical installation Contents of this chapter This chapter contains instructions on wiring the brake units. 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 electrician, do not do installation or maintenance work.

Electrical installation 43 8. At the other end of the cables, leave the shields unconnected or ground them via a capacitor (eg. 3.3 nF / 630 V). WARNING! IEC 60664 and IEC 61800-5-1 require double or reinforced insulation between resistor live parts and the sensor. If the assembly does not fulfill the requirement, the I/O terminals on the control unit must be protected against contact and must not be connected to other equipment, or the temperature sensor must be isolated from the I/O terminals, for example, with a suitable relay.
