What this chapter contains
This chapter describes the commissioning procedure for a DCR kit. This is done
based on the procedure used for DCS800-S0x converters. Only the actions and
steps, which are different, are listed here.
Safety Instructions
The rebuilt kit together with the power part and other components being reused will
form a converter and a drive system very similar as a new converter module or a
new cubicle with a converter module built-in. Based on that the mechanical and
electrical danger installation and commissioning personal is exposed to during the
work is similar, sometimes even higher. There is some work, which will only be-
come necessary together with a rebuild kit like thyristor assignment, activation of
feedback signals and some tests and measurements not necessary to ready made
converters.
Because of that the
Safety Instructions which have been given within the
chapter before need to be observed with extreme care!
When listing the different steps of the start-up procedure additional warnings will
be given. Based on the possible variations caused by the individual projects not all
conditions can be covered. Please take that procedure as a general guideline and
be prepared for individual decisions concerning safety and security.
Points to be observed because of the situation
All relevant safety regulations must be observed in the installation, commissioning
and maintenance work.
Because the rebuild kit enclosure class is IP00, it´s main and auxiliary connections
and other electrical parts can be reached without any protection.
After the supply voltage is disconnected by the main switch, always ensure by
measuring that no part of the system has voltage or the system is protected with
sufficient touching cover before any work is started.
There might be live terminals inside the drive cabinet even after the supply voltage
has been disconnected by the any main switch, e.g. incoming busbars of the main
switch itself or external auxiliary power supplies.
Avoid unnecessary voltage withstand tests on any part of the unit.
