Mains Feeds versus Rectifier ID Mains Monitoring
The Minipack system is fed with 3 One-phase 230VAC Mains input circuits. Each input circuit is
internally connected to feed 2 rectifiers, in such a pattern that loads the 3 circuits evenly.
If your system is supplied from a 3-phase Mains input circuit, the use of a 3ph AC Input
Connection Kit, part 228898 or 238394, is required.
Plug-and-Play Rectifiers versus Mains Monitoring
When a rectifier is hot plugged in a power shelf for the first time, the Smartpack controller
assigns the next available ID number to the rectifier, starting with “01”.
When a previously installed (hot plugged) Minipack rectifier is inserted in a power shelf, the
Smartpack controller “recognizes” the module, and assigns the same ID to the rectifier. In other
words, the controller and the rectifier “remember” the assigned ID number, even after removing
and reinserting the rectifier in the shelf.
To achieve a more controlled ID assignment, you should always insert & hot-plug new Minipack
rectifiers in the power shelf, one module at a time, in following shelf position order: 1, 3, 5 and
2, 4, 6.
This position-versus-ID number relationship is very important for the correct monitoring of the
mains circuit, as the Smartpack controller always uses rectifier ID01, 02 and 03 to monitor the
Mains Feed 1, 2 and 3 respectively. If these rectifiers malfunction, rectifier ID 04, 05 and 06 will
automatically take over.
For example: accidentally inserting a rectifier with ID02 in a power shelf position internally
connected to mains feed 1, will cause the controller to monitor mains feed 1 “thinking“ it monitors
mains feed 2.
