NOTE: External overcurrent protection is not provided by this product, but is required by codes. Refer to
Tables
8: Recommended multi-core cable and fuse sizes for rectifier input, bypass input and UPS output
connections and
10: Minimum recommended multi-core cable and fuse sizes for battery connection for
wiring requirements. If an output lockable disconnect is required, it is to be supplied by the user.

CAUTION
To reduce the risk of a fire, connect only to a circuit that is provided with
maximum input circuit breaker current ratings from Tables
11: Rated and
maximum currents for each 200kW/240kVA model configuration for rated power
and voltage, rectifier input and UPS output / bypass,
12: Rated and maximum
currents for each 300kW/360kVA model configuration for rated power and
voltage, rectifier input and UPS output / bypass and
13: Rated and maximum
currents for rated power and voltage, battery 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 Tables
11: Rated and maximum currents for each 200kW/
240kVA model configuration for rated power and voltage, rectifier input and UPS output / bypass,
12: Rated and maximum currents for each 300kW/360kVA model configuration for rated power and
voltage, rectifier input and UPS output / bypass and
13: Rated and maximum currents for rated power and
voltage, battery. The recommended line-to-line load unbalance is 50% or less.
Source protection for the AC input to bypass must suit the characteristics of the load and take into account
effects such as inrush or starting current.
