3.2.4.3 CONNECTING THE CENTRIC TO THE ELECTRICAL
Any connection diagrams and/or installation instructions in this document are Gamatronic's
recommendation for connecting the UPS to the infrastructure of a typical customer site. These
recommendations are subject to modification, if such modification is necessary to bring the
installation into compliance with the local, state, provincial, or national electrical laws and
regulations in effect at the installation site, in whatever country that may be.
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).
Warning: When using a residual current device on the UPS output it must be Type B.
In the event that the UPS has been disconnected from the ac mains for four
months or longer following its delivery to the customer site, the UPS must be
connected to the ac mains and operated with no load for a period of four hours,
before applying a load.
