Operation 48, 96, and 160 kW 400 V 100 kW 208 V
Operation
Operation Modes
The UPS has three operation modes: normal operation, battery operation and
static bypass operation. If the UPS system includes a PDU, a PDU with modular
batteries, or an external maintenance bypass enclosure, the mode maintenance
bypass operation also becomes available.
Normal Operation
During normal operation, the UPS converts the utility/mains supply to conditioned
power for the connected load.
Battery Operation
During battery operation, the UPS provides conditioned power to the connected
load from its batteries for a finite period. The UPS transfers to battery operation if
the utility/mains power supply becomes unavailable or is outside the predefined
limits.

NOTE: If the system does not contain a PDU or PDU with modular batteries,
the Q1, Q2, and Q3 switches and the Q5 breaker (if present) should be
located in an optional external maintenance bypass enclosure. See the
documentation included with the maintenance bypass enclosure for additional
information.
NOTICE
RISK OF LOAD DROP
This procedure will disconnect the load.
Failure to follow these instructions can result in equipment damage.
NOTE: If shutdown via the display is disabled, then you cannot perform this
procedure and the message: Command not allowed, UPS configured to
never shutdown appears. If you want to enable shutdown via the display, this
is done by a Schneider Electric field service engineer.
1. Select UPS > UPS Power Control > Turn UPS Off and press the enter key.
2. Select No, Don’t Notify to shut down without delay and press the enter key.
NOTE: This action will cut all power to the load without shutting it down
first. If you want to shut down the servers first, then choose Yes, Notify
Servers. Note that this function is only available for servers with
PowerChute.

and the PDU with modular batteries (if applicable) and on the UPS (only for
Symmetra PX 48 kW) .
11. Disconnect all battery units by removing them (all battery types) or pulling
them out to the disconnect line (modular batteries only).
NOTICE
RISKOF TILTING AND MODULAR BATTERY DAMAGE
To ensure that the UPS cabinet and the modular battery cabinet does not
tip, do not pull out the modular battery units beyond the red disconnect line.
If you intend to completely remove the modular battery units, remove them
from the UPS cabinet and modular battery cabinets one at a time. If you
don’t pull the modular battery units out to the red disconnect line, this could
cause deep discharge/damage to the modular batteries.
Failure to follow these instructions can result in equipment damage.

Maintenance
Life Cycle Monitoring (LCM)
The Life Cycle Monitoring (LCM) function provides UPS preventive maintenance
advice. It is currently only supported on Symmetra PX 100 kW UPSs.
The display shows the following three messages:
Contact Schneider Electric for Secure Start-Up Start-up check is recommended. Please call the Schneider Electric
support center.
Warranty Expiring Soon The end of the contractual legal warranty. Please call the Schneider
Electric support center.
Technical Check Recommended Regular maintenance requirements and the end of service life
consumable components. Please call the Schneider Electric
support center.
In addition to these messages, the Warning LED lights up and the buzzer sounds.
These messages can be disabled by choosing Admin > Life Cycle Monitor >
Settings > Yes. This will cause the Warning LED to go out, the buzzer to stop
and remove any Life Cycle Monitoring messages.
