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 rated power and voltage, rectifier input and UPS
output / bypass, 12: Rated and maximum currents 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 rated power and voltage, rectifier input and
UPS output / bypass, 12: Rated and maximum currents 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.
Bypass and output overcurrent protection and bypass and output disconnect
switches must be provided by the user.
