UPS Installation Plan and Unpacking
CAUTION
To reduce the risk of fire, connect only to a circuit provided with maximum input
circuit breaker current ratings from Table 3-7 in accordance with local regulations.
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. The recommended line-to-line load unbalance is 50% or less with reference to
full load.
Readily accessible disconnect devices (Bypass and output overcurrent protection and bypass and output
disconnect switches) are to be supplied by the customer. Table 3-8 lists the Recommended Bypass Circuit
Breaker, Output Circuit Breaker and Bypass Fuse Ratings.
