GENERAL SAFETY REQUIREMENTS
DANGER! RISK OF DEATH OR ELECTRIC SHOCK!
Before performing maintenance on the unit it is necessary to strictly
observe the following safety points:
• Perform the block/exclusion procedure of the power supply and open
the main disconnector of the electrical panel.
• Make sure that all power supplies to the AD1000 (main and auxiliary
power) are disconnected before performing maintenance on the drive.
• Wait at least ten (10) minutes after disconnecting the power supply
before performing maintenance on the unit. Before accessing the motor
terminals ensure that the DC bus capacitors are discharged: checking
with a calibrated multimeter for 1000Vdc or above, that the DC voltage
is less than 40V. Refer to the safety label present on all drives.
• The output terminals of the braking switch present hazardous DC
tension (greater than 500V).
• The AD1000 is supplied with many automatic reset and restart functions
that can automatically restart the unit. Do not activate these functions if
dangerous situations can occur.
• Do not change the insulation distances or remove insulation roofing
and materials.
• The AD1000 provides a variable frequency control.
The motors and the loads must be able to function in the speed and
power range supplied by the drive.
• Coordinate the voltage and rated current of the motor and the drive.
The motor rated voltage must be greater than 1/2 of the input voltage
and the motor rated current must be 1/3 greater than the output current
of the AD1000.
• The AD1000, regardless of the output frequency, produces a pulse
output voltage with a peak value of about 1.4 times the AC input
voltage and with very short rise times. The voltage of these pulses can
nearly double, according to the characteristics of the cable, on the motor
terminals: make sure that the output cables and the motor insulation are
designed to withstand additional stresses.
• If it is necessary to perform the insulation tests on the motor and on
the cables, first disconnect the cables from the drive. It is not necessary
to carry out high potential tests on the AD1000 components.
• Be careful not to damage any part of the AD1000 during handling.
• Protect the drive from weather and adverse environmental conditions
(temperature, humidity, vibration, collision, etc.). If it is necessary to
temporarily store the drive outdoors, it is necessary to take special
precautions (see Chapter 5).
