3.9.4 Control connections.
In order for units connected in a parallel conguration to operate correctly, control cables are required to exchange
data between the various UPS units making up the parallel system, for management of correct load sharing and
synchronisation logic.
The cables in question are supplied with the UPS in case of standard parallel setting or are attached to the parallel
kit in case of later upgrading of the system.
