GENERAL SAFETY PRECAUTIONS
This section provides information related to the safety issues of which all personnel working with the GT3000 must be aware.
The information is general and concerns the risks associated with both the operation and the maintenance of the drive. Failure
to comply with the safety precautions may lead to personnel injury or death and to damage to the drive, the motor or the
machine.
♠ All electrical maintenance and installation operations on GT3000 must be performed by
qualified technicians.
♠ All standard electrical safety procedures must be followed:
¾ Never touch anything within the drive until you check that it is not hotand/or live.
¾ Always wear insulated or rubber safety shoes, and safety goggles.
¾ Never work alone.
¾ Never connect any grounded meters or oscilloscopes to the system.
¾ Never remove safety shields.
¾ Always use extreme caution when handling components or taking measurements
inside the enclosure.
¾ DANGER! RISK OF FIRE, HEAVY DAMAGE OR INJURIES! Never operate the drive without line fuses or using line
fuses different from the ones specified for it (see Chapter 3A for size and type). Wrong fuses may cause fire, injuries to
personnel or heavy damage to equipment and/or nearby connected parts. Some units need separate line fusing for fans
and auxiliary circuits.
¾ Do not apply power to the drive if any moisture, dust or caustic/corrosive chemicals may have entered the enclosure or
internal components.
¾ DANGER! RISK OF FIRE, HEAVY DAMAGE OR INJURIES! GT3000 drives are open type devices and must be installed
strictly as instructed in the GT3000 HARDWARE MANUAL, and in full compliance with existing industry standards and
regulations.
¾ DANGER! GT3000 and all connected devices MUST BE SUITABLY GROUNDED.
¾ DANGER! RISK OF FIRE, HEAVY DAMAGE OR INJURIES! The voltages on the output terminals of GT3000 are
dangerous when the drive is energized, even if the drive is not running. Again, be aware that the motor could spin at any
time as soon as the power supply is connected and capacitor bank is charged.
¾ If installed in an enclosure, never run the drive with cabinet doors open.
¾ DANGER! RISK OF DEATH OR ELECTRICAL SHOCK! The following safety instructions must be strictly obeyed before
servicing the unit:
♦ Perform supply power lockout/tagout procedure, and open the main
disconnect to the drive.
♦ Make sure that all power supplies coming into GT3000 (main supply and
auxiliaries supply) are disconnected before servicing the drive.
♦ Before servicing the drive or accessing the motor terminals wait at least ten
(10) minutes after disconnecting all input power supplies. Verify that the DC
link voltage is less than 40 Volts before proceeding. Use a multimeter rated for
1000 volts DC or more. Refer to the safety label that is placed on every drive.
♦ The DC voltages at the brake switch terminals are dangerous (higher than
500V).
DANGER! RISK OF FIRE, HEAVY DAMAGE OR INJURIES! Never store
flammable material in, on or near the drive enclosure.
GT3000 is provided with many automatic reset and restart functions. Such
functions may restart the unit automatically. Do not activate these functions if
danger situations may arise.
¾ Do not change the insulation distances or remove insulating materials and coverings.
