16 Safety
Safety in installation and maintenance
These warnings are intended for all who work on the drive, motor cable or motor.
 Electrical safety
WARNING! If you ignore the safety instructions, injury or death can occur. If
you are not a qualified electrician, do not do electrical work.
• Only qualified electricians are allowed to install and maintain the drive!
• Never work on the drive, motor cable or motor when input power is applied. After
disconnecting the input power, always wait for 5 minutes to let the intermediate
circuit capacitors discharge before you start working on the drive, motor or motor
cable.
• Always ensure by measuring with a multimeter (impedance at least 1 Mohm) that
there is no voltage between the drive input phases U1, V1 and W1 and the
ground.
• Do not work on the control cables when power is applied to the drive or to the
external control circuits. Externally supplied control circuits may carry dangerous
voltage even when the input power of the drive is switched off.
• Do not make any insulation or voltage withstand tests on the drive.
• Disconnect the internal EMC filter when installing the drive on an IT system (an
ungrounded power system or a high-resistance-grounded [over 30 ohms] power
system), otherwise the system is connected to ground potential through the EMC
filter capacitors. This may cause danger or damage the drive. See page 47. Note:
When the internal EMC filter is disconnected, the drive is not EMC compatible.
• Disconnect the internal EMC filter when installing the drive on a corner-grounded
TN system, otherwise the drive will be damaged. See page 47. Note: When the
internal EMC filter is disconnected, the drive is not EMC compatible.
• All ACS320 Drive End Grounding screws are removed at the factory. See Product
overview for location details.
• All ELV (extra low voltage) circuits connected to the drive must be used within a
zone of equipotential bonding, in other words, within a zone where all
simultaneously accessible conductive parts are electrically connected to prevent
hazardous voltages appearing between them. This is accomplished by a proper
factory grounding.
Notes:
• Even when the motor is stopped, dangerous voltage is present at the power
circuit terminals U1, V1, W1 and U2, V2, W2.
• For more technical information, contact the factory or your local ABB sales
representative.
