Safety instructions 13

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.
14 Safety instructions
3

• 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 61800-5-1, subclause 6.5.3, for example, "THIS MACHINE STARTS
AUTOMATICALLY".
• The maximum drive power cycles is five times in ten minutes. Power cycling the drive
too often 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 15

￭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 circulates).
• 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 mm
• 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.
16 Safety instructions

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.
Go through 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.)
• 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. 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.
• Make sure that the voltage between the drive DC busbars (+ and -) and the
grounding (PE) busbar is zero.
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. Install temporary grounding as required by the local regulations.
7. Ask the person in control of the electrical installation work for a permit to work.
Safety instructions 17

￭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 recommends not to attach the cabinet by arc welding. If you have to, obey the
welding instructions in the drive manuals.
Note:
• The motor cable terminals of the drive are at a dangerous voltage when the input power
is on, regardless of whether the motor is running or not.
• When the input power is on, the drive DC bus is at a dangerous voltage.
If brake chopper and resistor are in use, they are at a dangerous voltage. (Option +D150)
(Option +D151).
• External wiring can supply dangerous voltages to the relay outputs of the control units
of the drive.
• The Safe torque off function does not remove the voltage from the main and auxiliary
circuits. The function is not effective against deliberate sabotage or misuse.
Optical components
WARNING!
Obey these instructions. If you ignore them, damage to the equipment can occur.
• Handle the fiber optic cables with care.
• When you unplug the fiber optic cables, always hold the connector, not the cable itself.
• Do not touch the ends of the fibers with bare hands as the ends are extremely sensitive
to dirt.
• Do not bend the fiber optic cables too tightly. The minimum allowed bend radius is
35 mm (1.4 in).
Printed circuit boards
WARNING!
Use a grounding wrist band when you handle printed circuit boards. Do not touch
the boards unnecessarily. The boards contain components sensitive to electrostatic
discharge.

￭Grounding
These instructions are for all personnel who are responsible for the grounding of the drive.
WARNING!
Obey these instructions. If you ignore them, injury or death, or equipment
malfunction can occur, and electromagnetic interference can increase.
If you are not a qualified electrical professional, do not do grounding work.
• Always ground the drive, the motor and adjoining equipment. This is necessary for the
personnel safety. Proper grounding also reduces electromagnetic emission and
interference.
• Make sure that the conductivity of the protective earth (PE) conductors is sufficient. See
the electrical planning instructions of the drive. Obey the local regulations.
• Connect the power cable shields to protective earth (PE) terminals of the drive to make
sure of personnel safety.
• Make a 360° grounding of the power and control cable shields at the cable entries to
suppress electromagnetic disturbances.
• In a multiple-drive installation, connect each drive separately to the protective earth
(PE) busbar of the power supply.
Note:
• You can use power cable shields as grounding conductors only when their conductivity
is sufficient.
• As the normal touch current of the drive is higher than 3.5 mA AC or 10 mA DC, you
must use a fixed protective earth (PE) connection. The minimum size of the protective
earth conductor must comply with the local safety regulations for high protective earth
conductor current equipment. See standard IEC/EN 61800-5-1 (UL 61800-5-1) and the
electrical planning instructions of the drive.
Safety instructions 19

General safety in operation
These instructions are for all personnel that operate the drive.
WARNING!
Obey these instructions. If you ignore them, injury or death, or damage to the
equipment can occur.
• 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 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.
•Give a stop command to the drive before you reset a fault. If you have an external source
for the start command and the start is on, the drive will start immediately after the fault
reset, unless you configure the drive for pulse start. See the firmware manual.
• 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 61800-5-1, subclause 6.5.3, for example, "THIS MACHINE STARTS
AUTOMATICALLY".
Note:
• The maximum drive power cycles is five times in ten minutes. Power cycling the drive
too often can damage the charging circuit of the DC capacitors. If you need to start or
stop the drive, use the control panel keys or commands through the I/O terminals of the
drive.
• If the drive is in remote control mode, you cannot stop or start the drive with the control
panel.
Additional instructions for permanent magnet motor drives
￭Safety in installation, start-up, maintenance
These are additional warnings concerning permanent magnet motor drives. The other safety
instructions in this chapter are also valid.
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 not do work on the drive when a rotating permanent magnet motor is connected to
it. A rotating permanent magnet motor energizes the drive including its input and output
power terminals.
Before installation, start-up and maintenance work on the drive:
• Stop the drive.
• Disconnect the motor from the drive with a safety switch or by other means.
