5.4. VERTIV AND THIRD PARTY BRAND UPS IN THE SAME INSTALLATION
The device can also be used to synchronise Vertiv UPS with other brand UPS systems. The Vertiv units must
be configured as the Slave devices so that they follow the phase reference signal derived from the non-Vertiv
Master UPS. UPS1 and 2 may be configured as parallel or single units, see Fig. 6.

Installation tips: UPS 1 and 2 should be configured in order to follow external synchronism signal. This is
achieved by setting the main synchronization source to external signal: otherwise UPS will be in phase with its
own bypass line and will follow external synchronization only when this is out of tolerance.
