Ordinary maintenance

6.4.1 Power module hot-swap replacement or inclusion of new modules

Archimod HE 240-480 allows the hot-swap replacement of the power modules if they fail or if new modules are inserted.

The load is always protected by the UPS without being supplied by the bypass line.

The procedure requires the turning off of the modules that are managed by the same command board. The load is

INDICATION

To use the hot-swap function, it is necessary to have sized the UPS properly. If the percentage of the load does not allow

the hot-swap without overload, perform the manual bypass mode maintenance procedure.

The command boards (CM) and the power modules (PM) are identified by a unique address inside the system, as shown
