11.2External Breakers

The G8000 UPS units are not equipped with circuit breakers. Qualified personnel should provide the external breakers for the AC input/output, bypass input and DC input.

See Figure 11.1 – External Wiring Diagram, for the circuit position of the breakers.

Table 11.3 shows the G8000 UPS minimum external breaker rating for each capacity. The bypass input and the AC output require 3-pole breakers.
