3.2.4.3 CONNECTING THE CENTRIC TO THE ELECTRICAL PANEL
Suitably rated circuit breakers must be installed between the Centric and the electrical panel.
Refer to Figure 8 or Figure 9 for system connections, and Table 2 and Table 3 for circuit breaker
recommendations.
See Chapter 8 for a discussion of the issue of circuit breaker selectivity.
Connection of the Centric UPS to the electrical panels must be performed only by a licensed
electrician experienced with similar systems.
Warning: When two separate input lines are used for rectifier and bypass input,
the Neutral line must be shared (as in Figure 8 and Figure 9).
