For the external battery cabinet's grounding information, please refer to:
Figure 5-19: Grounding Diagram_ Single Unit
Figure 5-25: Grounding Diagram_ Parallel Units
The external battery cabinet's protective device must be planned and designed by quali-
there are four selections, which are (1) a 4-pole DC circuit breaker or DC isolated switch
connected in series with a DC fuse, (2) a 3-pole DC circuit breaker or DC isolated switch
connected in series with a DC fuse, (3) a 4-pole DC circuit breaker and (4) a 3-pole DC
circuit breaker. For relevant values, please refer to Table 5-4. When choosing the ex-
ternal battery cabinet's protective device, please take the following factors into consid-
eration: (1) over current between the UPS and battery circuit, (2) short circuit, (3) wire/
cable materials, and (4) local electrical regulations. If you have any questions about the
external battery cabinet's protective device, please contact Delta service personnel. For
