Safety instructions
Contents of this chapter
This chapter contains the safety instructions which you must obey when you install, start-up,
operate and do maintenance work on the drive. If you ignore the safety instructions, injury,
death or damage can occur.
Use of warnings and notes
Warnings tell you about conditions which can cause injury or death, or damage to the
equipment. They also tell you how to prevent the danger. Notes draw attention to a particular
condition or fact, or give information on a subject.
The manual uses these warning symbols:
WARNING!
Electricity warning tells about hazards from electricity which can cause injury or
death, or damage to the equipment.
WARNING!
General warning tells about conditions other than those caused by electricity, which
can cause injury or death, or damage to the equipment.
WARNING!
Electrostatic sensitive devices warning tells you about the risk of electrostatic
discharge which can cause damage to the equipment.

Safety instructions 15

General safety in installation, start-up and maintenance
These instructions are for all personnel who do work on the drive.
WARNING!
Obey these instructions. If you ignore them, injury or death, or damage to the
equipment can occur.
• Keep the drive in its package until you install it. After unpacking, protect the drive from
dust, debris and moisture.
•Use the required personal protective equipment: safety shoes with metal toe cap, safety
glasses, protective gloves and long sleeves, etc. Some parts have sharp edges.
• Lift a heavy drive with a lifting device. Use the designated lifting points. See the
dimension drawings.
• Incorrect lifting can cause danger or damage. Obey the local laws and regulations
applicable to lifting, such as requirements for planning the lift, for capacity and condition
of lifting equipment, and for training of personnel.
• The lifting bars attached to large drive cabinets are heavy. Be careful when removing
or reinstalling the bars. Whenever possible, use a lifting device attached to the
designated lifting points.
• Attach the drive cabinet to the floor to prevent it from toppling over. The cabinet has a
high center of gravity. When you pull out heavy components or power modules, there
is a risk of overturning. Attach the cabinet also to the wall when necessary.
• Do not stand or walk on the cabinet roof. Make sure that nothing presses against the
roof, side or back plates or door. Do not store anything on the roof while the drive is in
operation.
•Be careful when handling a tall module. The module overturns easily because it is heavy
and has a high center of gravity. Whenever possible, secure the module with chains.
Do not leave an unsupported module unattended especially on a sloping floor.

• Beware of hot surfaces. Some parts, such as heatsinks of power semiconductors, and
brake resistors, remain hot for a while after disconnection of the electrical supply.
• Make sure that debris from drilling, cutting and grinding does not enter the drive during
the installation. Electrically conductive debris inside the drive may cause damage or
malfunction.
• Make sure that there is sufficient cooling. See the technical data.
• Keep the cabinet doors closed when the drive is powered. With the doors open, a risk
of a potentially fatal electric shock, arc flash or high-energy arc blast exists. If you cannot
avoid working on a powered drive, obey the local laws and regulations on live working
(including – but not limited to – electric shock and arc protection).
• Before you adjust the drive operation limits, make sure that the motor and all driven
equipment can operate throughout the set operation limits.
• Before you activate the automatic fault reset or automatic restart functions of the drive
control program, make sure that no dangerous situations can occur. These functions
reset the drive automatically and continue operation after a fault or supply break. If
these functions are activated, the installation must be clearly marked as defined in
IEC/EN/UL 61800-5-1, subclause 6.5.3, for example, "THIS MACHINE STARTS
AUTOMATICALLY".
•The maximum number of drive power-ups is five in ten minutes. Too frequent power-ups
can damage the charging circuit of the DC capacitors.
• If you have connected safety circuits to the drive (for example, Safe torque off or
emergency stop), validate them at start-up. See separate instructions for the safety
circuits.
Note:
• If you select an external source for the start command and it is on, the drive will start
immediately after fault reset unless you configure the drive for pulse start. See the
firmware manual.
• If the drive is in remote control mode, you cannot stop or start the drive with the control
panel.
• Only authorized persons are allowed to repair a malfunctioning drive.
Safety instructions 17

￭Work on the liquid cooling system
These instructions are intended for all personnel that do installation, commissioning and
maintenance work on the liquid cooling system.
WARNING!
Obey these instructions. If you ignore them, injury or death, or damage to the
equipment can occur.
• Use the required personal protective equipment. See the Safety data sheet for
Antifrogen®L coolant by Clariant (www.clariant.com) for the instructions on the
respiratory, hand and eye protection when handling the coolant.
• Beware of hot, high-pressure coolant (6 bar, max. 50 °C) that is present in the internal
cooling circuit when it is in operation. Before you disconnect a pipe, release the pressure.
Close the appropriate stop valve(s). If necessary, stop the cooling circuit pumps.
• Avoid skin contact with coolant. If coolant splashes onto the skin or in the eyes, rinse
immediately with plenty of water. Do not syphon it by mouth. If you swallow or get it
into the eyes, seek medical advice.
• Before the drive power up, make sure that the internal cooling circuit is filled up with
coolant, and the cooling is in operation (coolant is circulating).
• Make sure that coolant meets the ABB specification. See the appropriate hardware
manual of the drive/unit.
• To avoid breaking the coolant pipes, do not overtighten the nuts of the unions. Leave
2 to 3 millimeters (0.08 to 0.12 inches) of thread visible.
2…3 mm (0.08 … 0.12″)
• Do not drain coolant into the sewer system.
• If you need to store the drive in temperature below -15 °C (5 °F), drain the cooling
circuit, or make sure that it is filled with the coolant specified by ABB.
• Drives with the cooling unit: Do not open the cooling unit pump inlet or outlet valves
before filling up the coolant circuit. The pumps are filled with a mixture at the factory to
prevent corrosion and the valves are closed at the factory.
• Drives with the cooling unit: Do not run the cooling unit pump dry.

Electrical safety in installation, start-up and maintenance
￭Electrical safety precautions
These electrical safety precautions are for all personnel who do work on the drive, motor
cable or motor.
WARNING!
Obey these instructions. 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 or maintenance
work.
Do these steps before you begin any installation or maintenance work.
1. Clearly identify the work location and equipment.
2. Disconnect all possible voltage sources. Make sure that re-connection is not possible.
Lock out and tag out.
• Open the main disconnecting device of the drive.
• Open the charging switch if present.
• Open the disconnector of the supply transformer. (The main disconnecting device
in the drive cabinet does not disconnect the voltage from the AC input power
busbars of the drive cabinet.)
• Close the grounding switch or switches ([Q9], option +F259) if present. Do not use
excessive force as the switch has electromagnetic interlocking.
• Open the auxiliary voltage switch-disconnector (if present), and all other possible
disconnecting devices that isolate the drive from dangerous voltage sources.
• In the liquid cooling unit (if present), open the switch-disconnector of the cooling
pumps.
• If you have a permanent magnet motor connected to the drive, disconnect the
motor from the drive with a safety switch or by other means.
• Disconnect all dangerous external voltages from the control circuits.
• After you disconnect power from the drive, always wait 5 minutes to let the
intermediate circuit capacitors discharge before you continue.
3. Protect any other energized parts in the work location against contact.
4. Take special precautions when close to bare conductors.
5. Measure that the installation is de-energized. Use a quality voltage tester. If the
measurement requires removal or disassembly of shrouding or other cabinet structures,
obey the local laws and regulations applicable to live working (including – but not limited
to – electric shock and arc protection).
•Before and after measuring the installation, verify the operation of the voltage tester
on a known voltage source.
• Make sure that the voltage between the drive input power terminals (L1, L2, L3)
and the grounding (PE) busbar is zero.
• Make sure that the voltage between the drive output terminals (T1/U, T2/V, T3/W)
and the grounding (PE) busbar is zero.
Safety instructions 19

Important! Repeat the measurement also with the DC voltage setting of the tester.
Measure between each phase and ground. There is a risk of dangerous DC voltage
charging due to leakage capacitances of the motor circuit. This voltage can remain
charged for a long time after the drive power-off. The measurement discharges the
voltage.
• Make sure that the voltage between the drive DC terminals (UDC+ and UDC-) and
the grounding (PE) terminal is zero. In cabinet-built drives, measure between the
drive DC busbars (+ and -) and the grounding (PE) busbar.
WARNING!
The busbars inside the cabinet of liquid-cooled drives are partially coated.
Measurements made through the coating are potentially unreliable, so only
measure at uncoated portions. Note that the coating does not constitute a safe
or touch-proof insulation.
6. If the drive is not equipped with a grounding switch, install temporary grounding as
required by the local regulations.
7. Ask for a permit to work from the person in control of the electrical installation work.
￭Additional instructions and notes
WARNING!
Obey these instructions. 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 or maintenance
work.
• Keep the cabinet doors closed when the drive is powered. With the doors open, a risk
of a potentially fatal electric shock, arc flash or high-energy arc blast exists.
• Make sure that the electrical power network, motor/generator, and environmental
conditions agree with the drive data.
• Do not do insulation or voltage withstand tests on the drive.
• If you have a cardiac pacemaker or other electronic medical device, keep away from
the area near motor, drive, and the drive power cabling when the drive is in operation.
There are electromagnetic fields present which can interfere with the function of such
devices. This can cause a health hazard.
• ABB does not recommend attaching the cabinet by arc welding. If you have to, obey
the welding instructions in the drive manuals.
Note:
• When the drive is connected to the input power, the motor cable terminals and the DC
bus are at a dangerous voltage.
The brake circuit, including the brake chopper (option +D150) and brake resistor (option
+D151) are also at a dangerous voltage.
