To which products this chapter applies This chapter applies to the ACS800-01/U1, the ACS800-02/U2 and the ACS800-04/ Use of warnings and notes There are two types of safety instructions throughout this manual: warnings and notes.
• ACS800-02 with enclosure extension: The main switch on the cabinet door does not remove the voltage from the input busbars of the drive. Before working on the drive, isolate the whole drive from the supply.
In addition, connect the cable shields to protective earth (PE) in order to meet safety regulations. (ACS800-02: 360° high frequency grounding of cable entries is not required at the drive end.) •...
ACS800-01: The drive is heavy. Do not lift it alone. Do not lift the unit by the front cover. Place the unit only on its back. ACS800-02, ACS800-04: The drive is heavy. Lift the drive by the lifting lugs only. Do not tilt the unit. The unit will overturn from a tilt of about 6 degrees.
Permanent magnet motor These are additional warnings concerning permanent magnet motor drives. WARNING! Do not work on the drive when the permanent magnet motor is rotating. Also, when the supply power is switched off and the inverter is stopped, a rotating permanent magnet motor feeds power to the intermediate circuit of the drive and the supply connections become live.

This chapter describes the construction and operating principle of the drive in short. The ACS800-02/U2 The ACS800-02 is a free-standing drive for controlling AC motors. In the basic unit, the cabling direction is from below. When an optional enclosure extension is connected next to the basic unit, the cables can also be led from above.
Type code The type code contains information on the specifications and configuration of the drive. The first digits from left express the basic configuration (e.g. ACS800-02- 0170-5). The optional selections are given thereafter, separated by + signs (e.g. +E202). The main selections are described below. Not all selections are available for all types.

All AMA machines (manufactured in Helsinki) to be supplied by a drive have form-wound windings. All HXR machines manufactured in Helsinki since 1997 have form-wound windings. Note 5: ABB motors of types other than M2_, M3_, HX_ and AM_ Select according to non-ABB motors.
(see Technical Data). ACS800-01/U1, ACS800-02/U2 without enclosure extension and ACS800-04/U4 When placed at the distribution board, standard gG (US: CC or T for the ACS800- U1; T or L for the ACS800-U2 and the ACS800-U4) fuses will protect the input cable in short-circuit situations, restrict drive damage and prevent damage to adjoining equipment in case of a short-circuit inside the drive.
An emergency stop function is optionally available for stopping and switching off the whole drive. Two stop categories according to IEC/EN 60204-1 (1997) are available: immediate removal of power (Category 0 for ACS800-02/U2 and ACS800-07/U7) and controlled emergency stop (Category 1 for ACS800-07/U7).
Restarting after an emergency stop After an emergency stop, the emergency stop button must be released and the drive started by turning the operating switch of the drive from position “ON” to “START”. Prevention of Unexpected Start (ACS800-07/U7 only) The drive can be equipped with an optional Prevention of Unexpected Start function according to standards IEC/EN 60204-1: 1997;...
Selecting the power cables General rules Dimension the mains (input power) and motor cables according to local regulations: • The cable must be able to carry the drive load current. See chapter Technical data for the rated currents. ° • The cable must be rated for at least 70 C maximum permissible temperature of conductor in continuous use.
Alternative power cable types Power cable types that can be used with the drive are represented below. Recommended Symmetrical shielded cable: three phase conductors A separate PE conductor is required if the conductivity and a concentric or otherwise symmetrically of the cable shield is < 50 % of the conductivity of the constructed PE conductor, and a shield phase conductor.
Additional US requirements Type MC continuous corrugated aluminum armor cable with symmetrical grounds or shielded power cable must be used for the motor cables if metallic conduit is not used. For the North American market, 600 VAC cable is accepted for up to 500 VAC. 1000 VAC cable is required above 500 VAC (below 600 VAC).
Equipment connected to the motor cable Installation of safety switches, contactors, connection boxes, etc. To minimize the emission level when safety switches, contactors, connection boxes or similar equipment are installed in the motor cable (i.e. between the drive and the motor): •...
Protecting the relay output contacts and attenuating disturbances in case of inductive loads Inductive loads (relays, contactors, motors) cause voltage transients when switched off. The relay contacts on the RMIO board are protected with varistors (250 V) against overvoltage peaks. In spite of this, it is highly recommended to equip inductive loads with noise attenuating circuits [varistors, RC filters (AC) or diodes (DC)] in order to minimize the EMC emission at switch-off.
Control panel cable In remote use, the cable connecting the control panel to the drive must not exceed 3 metres (10 ft). The cable type tested and approved by ABB is used in control panel option kits. Planning the electrical installation...
Connection of a motor temperature sensor to the drive I/O WARNING! IEC 60664 requires double or reinforced insulation between live parts and the surface of accessible parts of electrical equipment which are either non- conductive or conductive but not connected to the protective earth. To fulfil this requirement, the connection of a thermistor (and other similar components) to the digital inputs of the drive can be implemented in three alternate ways:...
