40–130 kVA 480 V,20–120 kVA 400 V Operation
Operation
Operating Modes
Normal (Double Conversion) Mode
When in normal mode, the UPS supports the load with conditioned power from the
input source.
The load LED is on.
ECO Mode (Single UPS Only)
The main advantage of ECO mode is a reduction in the consumption of electrical
power. In this mode, under normal conditions, the UPS operates continuously on
power from the bypass source. If the bypass mains goes outside tolerance, a
transfer to the inverter takes place. The load may experience a short duration
interruption of power (3 ms) during this transfer. When the bypass mains comes
back within tolerance, the load is again supplied with power from the bypass
source.
The load LED is ON.
Frequency Converter Mode
Frequency converter mode is a configuration without a bypass source connected.
When the power is turned on, the UPS starts up and goes automatically online to
supply the load with a frequency different from the input. Only the Galaxy 5500 400
V UPS can function as a frequency converter.
Load on Battery Power
If the utility/mains supply is missing, the UPS transfers to battery operation and
supports the load with conditioned power from the DC source.
The warning LED is ON and the buzzer sounds intermittently.
14 990-5219B-001
Operation 40–130 kVA 480 V,20–120 kVA 400 V
Synchronization Module Modes (Option)
The synchronization module synchronizes two or more power sources supplying a
static transfer switch. Two modes are available:
•Automatic-source mode: Both sources can be controlled.
•Fixed source mode: Only one source can be controlled.
When the UPS is controlled by the synchronization module, the warning alarm LED
is ON and the display shows this message: UPS on external synchronization.
On the synchronization module, the following LEDs are ON:
• The SYNCHRONISED SOURCE LED is ON. The phase deviation is within
tolerances. Sources are synchronized.
• The S2 CONTROLLED SOURCE LED is ON. Reference source is source S1.
Controlled source is source S2.
• The ACTIVATED LED is ON. Synchronization function is activated.

Servicing Batteries
DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION OR ARC FLASH
• Battery circuit breakers must be installed according to the specifications and
requirements as defined by Schneider Electric.
• Servicing of batteries must only be performed or supervised by qualified
personnel knowledgeable of batteries and the required precautions. Keep
unqualified personnel away from batteries.
• Do not dispose of batteries in a fire as they can explode.
• Do not open, alter, or mutilate batteries. Released electrolyte is harmful to the
skin and eyes. It may be toxic.
Failure to follow these instructions will result in death or serious injury.
DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
Batteries can present a risk of electric shock and high short circuit current. The
following precautions must be observed when working on batteries
• Remove watches, rings, or other metal objects.
• Use tools with insulated handles.
• Wear protective glasses, gloves and boots.
• Do not lay tools or metal parts on top of batteries.
• Disconnect the charging source prior to connecting or disconnecting battery
terminals.
• Determine if the battery is inadvertently grounded. If inadvertently grounded,
remove source from ground. Contact with any part of a grounded battery can
result in electric shock. The likelihood of such shock can be reduced if such
grounds are removed during installation and maintenance (applicable to
equipment and remote battery supplies not having a grounded supply circuit).
Failure to follow these instructions will result in death or serious injury.
DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
When replacing batteries, always replace with the same type and number of
batteries or battery packs.
Failure to follow these instructions will result in death or serious injury.
