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.

Static Bypass Operation

Static bypass operation is a feature that keeps the load supplied directly from the
utility/mains supply during different scenarios on the UPS or downstream from the
UPS. In static bypass operation, the utility/mains is supplying power to the
connected load directly, bypassing all internal UPS functions.

Maintenance Bypass Operation (Optional)

The UPS can be connected to a PDU, a PDU with modular batteries, or an
external maintenance bypass enclosure that enables the user to bypass the UPS
completely for maintenance purposes that might even include replacement of the
entire UPS. In this situation, the connected load will then be fed directly from the
utility/mains supply, and there will be no conditioning of the supply or battery
backup of the load.

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
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.

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:

Display Message Description – corrective action

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.

Parts Replacement

DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
Apply appropriate personal protective equipment (PPE) and follow safe
electrical work practices for all part replacement procedures.
Failure to follow these instructions will result in death or serious injury.

Determine if you need a Replacement Part

To determine if you need a replacement part, contact Schneider Electric and
follow the procedure below so that the representative can assist you promptly:
1. In the event of an alarm condition, scroll through the alarm lists, record the
information, and provide it to the representative.
2. Write down the serial number of the unit so that you will have it easily
accessible when you contact Schneider Electric.
3. If possible, call Schneider Electric from a telephone that is within reach of the
display so that you can gather and report additional information to the
representative.
4. Be prepared to provide a detailed description of the problem. A representative
will help you solve the problem over the telephone, if possible, or will assign a
return material authorization (RMA) number to you. If a module is returned to
Schneider Electric, this RMA number must be clearly printed on the outside of
the package.
5. If the unit is within the warranty period and has been started up by Schneider
Electric, repairs or replacements will be performed free of charge. If it is not
within the warranty period, there will be a charge.

6. If the unit is covered by a Schneider Electric service contract, have the

contract available to provide information to the representative.

Return Parts to Schneider Electric

To return an inoperable part to Schneider Electric, contact Schneider Electric
customer support to obtain an RMA number.
Pack the part in the original shipping materials, and return it by insured, prepaid
carrier. The customer support representative will provide the destination address.
If you no longer have the original shipping materials, ask the representative about
obtaining a new set.
• Pack the part properly to avoid damage in transit. Never use styrofoam beads
or other loose packaging materials when shipping a part. The part may settle
in transit and become damaged.
• Enclose a letter in the package with your name, RMA number, address, a
copy of the sales receipt, description of the problem, a phone number, and a
confirmation for payment (if necessary).
NOTE: Damages sustained in transit are not covered under warranty.
