NOTE
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 on page 31 for wiring
requirements. If an output lockable disconnect is required, it is to be supplied by the user.
CAUTION
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 on page 31 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 on page 31. 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 on page 9.
