GENERAL
This document shows christmas tree for the ACS800-104 and describes how to replace the IGBT
modules and the fan of the ACS800-104 drive.
ACS800-104 MAINTENANCE INSTRUCTION
WARNING! All electrical installation and maintenance work on the ACS 800 should
be carried out by qualified electricians.
Do not attemp any work on a powered ACS 800. 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 (impedance at least 1M Ω) to ensure that the frequency converter is
discharged before beginning work.
All insulation tests must be carried out with the ACS 800 disconnected from the
cabling.
The ACS 800 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 attemped with mains power applied.
There can be dangerous voltage inside the ACS 800 from external control circuits
when the ACS 800 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 appropiate care when working with the unit.
ESD (Electro Static Discharge) The printed circuit boards contain integrated
circuits that are extremely sensitive to electrostatic discharge. Exercise appropiate
care when working on the unit to avoid permanent damage to the circuits. Do not
touch the boards unnecessarily.
WARNING! Only qualified electrians are allowed to carry out work described in this
instruction. Before working with the ACS 800 or handling the IGBT modules, read
carefully the Safety Instruction on the ACS800 Hardware Manual. Ignoring the safety
instructions can cause injury or death.
