Protective Earth
External overcurrent protection is not provided by this product, but is required by codes. Refer to Table 3-6:
Minimum recommended multi-core cable and fuse sizes for wiring requirements. If an output lockable disconnect
is required, it is to be supplied by the user.
To reduce the risk of fire, connect only to a circuit provided with maximum input circuit breaker current ratings
from Table 3-7: Rated and maximum currents for rated power and voltage in accordance with the national and
local installation rules.
The line-to-line unbalanced output capability of the UPS is limited only by the full load per phase current
values for AC output to critical load shown in Table 3-7: Rated and maximum currents for rated power and
voltage. The recommended line-to-line load unbalance is 50 % or less.
Source Protection for the AC Input to Bypass should suit the characteristics of the load and take account of
effects such as Inrush or Starting Current. Bypass and output overcurrent protection and bypass and output
disconnect switches are to be provided by the user.
For UPS wiring diagrams, see Chapter 2.1 Looking inside the UPS system.
