6.2.2. Rectifiers
Unlike on other power plants, the rectifiers used in the AP6C75AA Helios
Candeo power system do not need to be identified by physical designation, this
for two reasons:
•
These rectifiers are of the plug-in type and they do plug in a universal back-
bone rather than in dedicated shelves. Should a rectifier become defective, it
would be then replaced by a spare unit and the designation sequence would
thus be broken.
•
Each rectifier has an electronic signature associated with its serial number.
This signature is programmed in the System Manager module where it is also
associated with its physical position in the frame.
The rectifiers have thus a virtual designation.
6.2.3. Distribution
All distribution circuits shall be properly identified at the front and, if possible,
at the rear of the protection devices (circuit breakers) without any exception.
On the AP6C75AA Helios Candeo power system, the front designation of
distribution circuits is done on the label behind the door of the Distribution
Module (visible when the door is in the open position).
Refer to the job drawings for the name of the circuit associated with each circuit
breaker, and to the equipment drawings for the location of the stamping on the
Distribution Modules. The stamped information should at least include the
equipment name, the equipment location (bay No.) and the circuit breaker
rating.
