Start-up
Contents of this chapter
This chapter contains start-up instructions of the diode supply unit.
The underlined tasks are necessary only for certain cases. The symbols in brackets, for
example [Q1], refer to the item designations used in the circuit diagrams. If a task is valid
only for a certain option device or feature, the option code is given in brackets, for example,
(option +F259).
Note: The instructions do not cover all possible supply unit configurations. Always refer to
the delivery-specific circuit diagrams when proceeding with the start-up. This default start-up
procedure is valid for a supply unit equipped with a main breaker ([Q1], option +F255) and
an external auxiliary voltage supply (option +G307).
Note: For the functional safety options, the start-up instructions are given in separate option
manuals. Reserve the necessary option manuals at hand before the supply unit start-up.
Obey their start-up instructions.
WARNING!
Obey the safety instructions during the start-up procedure. See ACS880
liquid-cooled multidrive cabinets and modules safety instructions
(3AXD50000048633 [English]). If you ignore the safety instructions, injury
or death, or damage to the equipment can occur.
If you are not a qualified electrical professional, do not do installation or
maintenance work.
