Safety Notice

Applicable products: Suitable for ACS800-01/U1 and ACS800-02/U2 products.

Warning and Caution

Warning: Remind of situations that may cause serious injury or death and/or damage to equipment, such as dangerous voltage, electrostatic discharge, etc.

Attention: Remind users of special situations or events, or introduce relevant information on the topic, such as dangerous high voltage at motor cable terminals.

Installation and maintenance work

Only qualified electrical engineers are allowed to install and maintain transmission units.

It is prohibited to install or repair transmission units, motor cables or motors with electricity. After cutting off the input power, wait for at least 5 minutes until the intermediate circuit capacitor is discharged, and use a multimeter to measure and confirm the discharge before operation.

Do not operate control cables when the transmission unit or external control circuit is energized.

All insulation tests must be conducted with the cable disconnected, and ensure the correct phase sequence when reconnecting the cable.

grounding

Proper grounding is necessary to ensure the safety of personnel, reduce electromagnetic radiation and interference. The cross-sectional area of the grounding wire must meet safety regulations, and multiple equipment grounding terminals cannot be connected in series.

In scenarios that comply with European CE standards, cable entrances should maintain a 360 degree high-frequency grounding, and the cable shielding layer should be connected to the protective grounding wire (PE).

Do not install frequency converters with EMC filters in floating or high ground resistance power systems.

Mechanical Installation

The transmission unit is heavy and should not be carried by a single person. When carrying, do not let the front panel bear the weight and rely on lifting the back for transportation.

Ensure that drilling debris does not enter the transmission unit during installation, ensure sufficient cooling space, and do not fix the transmission unit by riveting or welding.

operate

Before debugging the transmission unit, ensure that the motor and driven equipment are suitable for operation within the speed range provided by the transmission unit.

Do not activate the automatic fault reset function of standard applications in situations where danger may occur.

Do not use the main power circuit breaker to control the start and stop of the motor. Instead, use control commands from the control panel keys or transmission unit I/O board.

Permanent magnet motor

When ACS800 is used to drive permanent magnet motors, only scalar control mode can be used.

When the permanent magnet motor is running, do not operate the transmission unit, as its operation transfers electrical energy back to the intermediate circuit. Even if the inverter is not working, the power supply will still charge the transmission system.

During installation and maintenance, use a fuse switch to disconnect the motor from the transmission unit. If possible, lock the motor shaft, connect the motor connection terminals together, and ground them.

Do not operate the permanent magnet motor at speeds higher than the rated speed to avoid overvoltage and capacitor bank rupture.

Product Overview

ACS800-01/U1: A wall mounted transmission unit used to control low-voltage AC asynchronous motors, with different external specifications (R2~R6), protection levels including IP21 (NEMA1) and IP55 (NEMA4, indoor only), etc. The control panel is CDP312R, including printed circuit boards such as main circuit board (RINT), motor control and I/O control board (RMIO), etc. The motor control mode can choose direct torque control (DTC) or scalar control.

ACS800-02/U2: There is relatively little mention in the document, and the external specifications are R7 and R8. Other information can refer to the relevant content of ACS800-01/U1. Some chapters of the two are common, such as safety instructions, electrical installation design, and braking resistors.

Installation

Mechanical Installation

Unpacking and inspection: After unpacking, check for any damage to the appearance, verify if the nameplate of the frequency converter matches the order, and check if the optional modules and equipment are complete.

Preparation before installation: Install vertically, place the radiator against the wall, check if the walls and floors of the installation site meet the requirements, ensure that there is enough space around the transmission unit for cooling air circulation, facilitate maintenance and repair, and pay attention to the space requirements when placing equipment of different protection levels up and down.

Installation method: including wall mounted installation and cabinet installation. Wall mounted installation requires marking the installation hole position with a punching template, fixing screws or bolts, installing the transmission unit and tightening it; Attention should be paid to the horizontal installation distance between the frequency converters when installing inside the cabinet, to prevent the recirculation of cooling air, and to set up air baffles.
