Warnings and Cautionary Uses

This manual contains two types of safety instructions: warnings and cautions. Warnings alert you to situations that could result in serious injury or death and/or damage to the equipment.

damage to equipment. Warning messages also tell you how to avoid accidents. A caution draws your attention to a special situation or event, or introduces a topic

or event, or presents information about a topic. The symbols used for warnings are shown below:

Hazardous Voltage Warning: Warns of the presence of high voltage that could cause personal injury or equipment damage.

General Warning: Warns of non-electrical factors that can cause personal injury or equipment damage.

Electrostatic Discharge Warning: Warns of an electrostatic discharge that can cause equipment damage.

Installation and maintenance work

These warnings are aimed at those working with inverters, motor cables or motors. Ignoring these specifications will

result in personal injury or death.

Warning! Some electronic components on printed circuit boards are sensitive to electrostatic discharge. When handling circuit boards, wear a

grounding wrist strap. Do not touch the circuit board without reason.

Only qualified electrical engineers are permitted to install and maintain the drive unit.

- Do not install or service the drive unit, motor cables or motors while energised. After disconnecting the input power, wait at least 5 minutes for the intermediate circuits to be switched off.

After disconnecting the input power supply, wait at least 5 minutes until the intermediate circuit capacitors have been discharged. Before starting operation, you should also

Before starting operation, also measure the voltage between terminals UDC+ and UDC- with a multimeter (impedance at least 1 megohm) to make sure that the drive unit is discharged.

The drive unit is discharged.

- It is not permitted to operate the control cables while the drive unit or external control circuits are energised. Even if the mains supply to the ACS 800 is disconnected, there may still be internal problems caused by the ACS 800.

Even if the ACS 800 mains power supply is disconnected, dangerous voltages introduced by external control circuits may still be present inside.

- All insulation tests must be carried out with the cable disconnected.

- When reconnecting the cables, ensure that the phase sequence is correct.

NOTE

- Hazardous high voltages are present at the motor cable terminals whenever the input power to the ACS 800 drive is switched on, regardless of whether the motor is running or not.

Hazardous high voltages are present at the motor cable terminals whenever the ACS 800 drive input is switched on.

- The brake control terminals (UDC+, UDC-, R+ and R- terminals) are exposed to dangerously high DC voltages (more than 500 V).

Brake control terminals (UDC+, UDC-, R+ and R- terminals) are subject to dangerously high DC voltages (more than 500 V).

- Relay output terminals RO1 to RO3 are subject to dangerously high voltages when 115 V or 220 V (230 V) is switched on.

High voltage.

Grounding

These safety instructions are for those responsible for handling ACS 800 grounding. Improper grounding can

cause personal injury, death, or equipment failure, and can increase electromagnetic interference.

- Properly ground the ACS 800, motor, and connected equipment to ensure the safety of personnel under all circumstances and to reduce electromagnetic emissions and interference.

Ground the ACS 800, motor, and connected equipment properly to ensure the safety of personnel under all circumstances and to reduce electromagnetic emissions and interference.

- Make sure that the cross section of the grounding conductor is large enough to meet the requirements of safety regulations.

- The grounding terminals of several ACS 800 units must not be connected in series.

- In European CE compliant and other installations where reduction of EMC emissions is essential, the cable entry should be grounded at 360 degrees to a high frequency ground.

In European CE-compliant and other installations where EMC emissions must be reduced, the cable entry should be grounded to a 360-degree high-frequency ground to suppress electromagnetic interference. In addition, the cable shield must be connected to a protective earth wire (PE) to

(PE) to comply with safety regulations.

- Do not install EMC filters (option +E20) with EMC filters in power systems with floating or high earth resistance (>30 Ohms).

（Do not install inverters with EMC filters (option +E202 or +E200) in power systems with floating ground or high grounding resistance (>Ohms).

Note: Only the conductive cross-section of the cable shield is available.

- The cable shield can only be used as a grounding conductor for the device if the conductive cross-section dimensions comply with safety regulations.

- If the normal leakage current of the ACS 800 is greater than 3.5 mA (AC) or 10 mA (DC), a fixed protective earth conductor needs to be connected.

If the normal leakage current of the ACS 800 is greater than 3.5 mA (AC) or 10 mA (DC), it is necessary to connect a fixed protective earth wire.

Mechanical Installation

These precautions are for those who are responsible for installing the ACS 800. The transmission unit must be installed carefully and according to specifications to avoid damage to the equipment or injury.

Operation

These warnings are intended for those who intend to operate or are operating the drive unit. Ignoring these requirements may result in injury or damage to the equipment.

Ignoring these requirements may result in injury or damage to the equipment.

- The drive unit is heavy and should not be handled by one person. The drive unit is heavy and should not be handled by one person. The front panel should not be loaded during handling and must be handled by lifting the back.

The drive unit is heavy and should not be handled by one person.

- Ensure that drilling debris does not enter the drive unit during installation. If conductive debris is present inside the drive unit, it will damage the unit or

Ensure that sufficient cooling space is available.

- Ensure adequate cooling space.

- The drive unit should not be riveted or welded.

- Because the drive unit allows the motor to operate at higher or lower than rated speeds, make sure that the motor is not damaged before commissioning the drive unit and putting it into service.

Before commissioning the drive unit and putting it into operation, make sure that the motor and all driven equipment are suitable for operation within the speed range provided by the drive unit.

Before commissioning the drive unit and putting it into service, be sure that the motor and all driven equipment are suitable for operation within the speed range provided by the drive unit.

- Do not activate the automatic fault reset function of the standard application in case of possible danger. If

activated, the drive unit will be automatically reset and will continue to operate after a fault has occurred.

- Do not use the mains circuit breaker to control the starting and stopping of the motor. Use the control panel keys and , or use the

control commands from the drive unit I/O board. Because the maximum allowable charge rate for the ACS 800's DC capacitor bank is 5 charges per 10 minutes, the maximum allowable charge rate is 5 charges per 10 minutes.

ACS 800 DC capacitor bank is 5 times every 10 minutes.

Note: If the start command comes from an external signal

- If the start command comes from an external source and the source is ON, the ACS 800 (equipped with standard applications) will not start until the start command has been received from an external source and the source is ON.

800 (with standard application) will start immediately after a fault reset, unless the drive unit is configured for the ‘3-wire’ macro.

- If the control ground is not set to local control (L is not shown in the status line of the display), the control panel's

Stop button on the control disc does not stop the drive unit. To stop the drive unit with the control panel, press the LOC/REM key on the control panel.
