2.8. CONTROL
CONNECTIONS
In order for units connected in a parallel confi guration 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 the case of standard parallel setups or are attached to the parallel kit in the
case of a later system upgrade.
Parallel confi guration must only be activated by SOCOMEC qualifi ed personnel
; in each case arrange the control cables in
the relevant cable run as shown in fi gure 2.8-1, leaving the connector(s) unconnected (in the central UPS one incoming and one
outgoing control cable must be used).
