CAUTION
To reduce the risk of a fire, connect only to a circuit that is provided with
maximum input circuit breaker current ratings from Table
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
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 input and output overcurrent protection and bypass, output and
accessory disconnect switches must be provided by the user.
4.4 Unpack and unload the UPS
Before you start to unpack and unload the UPS, look at the TipNTell indicator on
the package surface. When you have unpacked and unloaded the UPS, look at
the DropNTell indicator on the back of the UPS. If the equipment has been
correctly transported in the upright position, the indicators should be intact. If the
TipNTell indicator arrow has turned all blue or the arrow head(s) of the
DropNTell are black, contact the appropriate parties to report inappropriate
transportation.
