2 Check that the voltage selection at the 3-phase auxiliary
transformers is made correctly in each phase.
3 Check that the external 3-phase auxiliary voltage is according to
the project data and within the permitted range.
4 The main switch of auxiliary supply can now be turned on.
Note: The EMC-filter (-Z5002) inside the drive may need to be
temporarily bypassed in case the fault current relay on the customer
side trips.
5 Check the output voltage of the auxiliary transformers.
After that, the voltage distribution inside the converter cabinets can
be switched on one by one by closing the respective circuit breakers
and protection switches.
6 Check the level of the AC/DC voltages (24 and 27 VDC).
5.3 Filling and Starting up the Cooling System
Follow the instructions in the Operation and Maintenance Manual in
Appendix A – Water Cooling Unit of the ACS 6000 User’s Manual
when filling and starting up the water cooling system.
Related parameter settings and measuring signals must be checked
before the cooling pumps are started.
Note: References to the parameter indices are valid for software
versions 3xxx. For other software versions, refer to the latest signal
and parameter documents delivered with the loading package.
Water cooling related parameters and signals are located in the
following groups:
• Group 4: Actual Values (from S800 I/O)
• Group 33: WCU Control
• Group 34: WCU Supervision
The following signals and parameters must be checked and set:
• Parameter 34.06 Water Inp Press Supervis
The parameter enables / disables the measurement the inlet
pressure of the cooling pumps in closed type water cooling systems.
• Parameter 34.21 FAIL Safe EOFF Input
The parameter enables / disables the Emergency OFF fail-safe
function. If enabled thesSource of the Emergency OFF signal is
input C2P3, AI810, Ch8.
• Parameters 34.26….31
