APC 6000 Diagram for a frequency converter with batteries, Static Switch Cubicle

Installation (cont.)

Note:

Both the rectifier-inverter cubicles and the Static Switch Cubicle can be supplied from a common mains, in which case there is only one upstream circuit breaker (same as the case of a single-unit UPS with a common Mains 1 and 2).
