1. General
1.1 Warnings
WARNING!
Any qualified electrician, who according to the local laws has the required legitimacy, is allowed to
perform installation and maintenance work on the ACX580 frame sizes R0-R5.
Do not attempt any work on a powered ACX580. After switching off the mains, always allow the
intermediate circuit capacitors 5 minutes to discharge before working on the frequency converter, the
motor or the motor cable. The voltage between each input terminal (U1, V1, W1) and earth must be
measured with a multimeter (impe
dance at least 1MΩ) to ensure that the frequency converter is
discharged before beginning work.
Always ensure by measuring with a multimeter (impedance at least 1 MΩ) that:
1.
There is no voltage between the drive input phases U1, V1 and W1 and the ground.
2.
There is no voltage between terminals UDC+ and UDC- and the ground.
3.
There is no voltage between terminals R+ and R- and the ground.
Also make sure that no one can accidentally power the system up while you’re working on the drive.
All insulation tests must be carried out with the ACX580 disconnected from the cabling.
Do not make any insulation or voltage withstand tests on any part of the drive.
The ACX580 motor cable terminals are at a dangerously high voltage when input power is applied,
regardless of motor operation. No work on the motor cable should be attempted with mains power
applied.
There can be dangerous voltage inside the ACX580 from external control circuits when the ACX580
input power is shut off. No work on the control cables should be attempted when power is applied to
the frequency converter or to the external control circuits. Exercise appropriate care when working
with the unit.
ESD (Electro Static Discharge): The printed circuit boards contain integrated circuits that are
extremely sensitive to electrostatic discharge. Use ESD –protection and exercise appropriate care
when working on the unit to avoid permanent damage to the circuits. Avoid unnecessary touching of
the boards.
WARNING!
Before working with the ACX580 read carefully the Safety Instruction on the ACX580 Hardware
Manual. Ignoring the safety instructions can cause injury or death.
