Chapter 12 Helpful information
sensitive IT equipment may need a constant voltage and frequency or risk damage. Care
should be taken whether the load could be damaged by transferring to unregulated bypass.
Industrial mode does work well in an electricity environment where inrush currents are an
issue however care must be taken as the entire node connected to the upstream breaker may
open dropping all loads.
Take for example, one load segment has a localized short circuit (the load has a short and is
malfunctioning), in IT mode, the inverter will provide line cycles such that the load segment
will fault out and not transfer to bypass and the remaining load segments will be protected.
In Industrial mode this case would transfer to bypass and the upstream breaker may open to
break the fault and the UPS will go on battery and may still experience the short and turn off
the output for all load segments.

Additional information on UPS firmware update
Note: Currently no firmware update for any Lenovo 5594 and 5595 UPS unit is available for
download. If a new firmware is to be applied Lenovo will provide a tech tip with according
information.
To perform a firmware update, the load must be in standby mode (Load off) but connect to the
utility power. Once the update is complete the UPS can be returned to operating mode (Load
on). This means that during the period of the firmware update, the Lenovo UPS unit does not
protect the attached load. Instead the load is running directly from utility power. The firmware
update takes around 10 minutes.
If this is an issue, a down time window for the protected load has to be scheduled.
Note: No downtime is needed for updating the Network Management Card.
