Safety Considerations
The UPS contains LETHAL VOLTAGES. All repairs should be performed
by trained service personnel. There are no userĆserviceable parts inside the UPS.
The UPS contains its own energy source (battery). The output
receptacles may be live even when the UPS is not connected to an AC supply.
There is high voltage present at terminals 9 and 10 (terminals for remote battery
connection) when a battery cabinet is connected to the UPS.
To fully deĆenergize the UPS, turn off the output breaker. Then turn off the
input breaker and the battery breaker.
All cabinets must be secured to keep them from moving after installation
is complete. Secure the cabinets by bolting the cabinets to the cabinet mounting
plate. Failure to do so violates safety rules and results in the unit losing its safety
agency approvals.

System Overview
During normal operation, incoming commercial power is filtered to reduce noise and
spikes. The rectifier provides isolated, regulated, and filtered DC power to the inverter.
A portion of the input power to the rectifier is used to charge the battery. The inverter
provides further regulated and filtered AC power to the load. In the event of a severe
overload or unit failure, the Auto Bypass feature (if enabled) switches the load to the
filtered input power. If bypass is not available, the inverter can still support difficult loads
for a short period of time.
If utility power falls out of tolerance, the UPS remains online, deriving power from the
battery. During extended power outages, the battery supplies power until nearly
discharged at which time the UPS shuts off power to the load. When the utility power
returns within tolerance, the UPS automatically restarts and supplies power to your
protected equipment while recharging the battery.
System Requirements
Determine the total load requirements, in voltĆamperes, of the equipment you intend to
protect with your UPS. The UPS load should not exceed the UPS rating. See Figure 1
and the following procedure to determine the total load requirements:
. Obtain the load ratings from either the nameplate or operator's manual of the
equipment you intend to protect. The ratings are listed in either watts (W),
amperes or amperes max (A), or voltĆamperes (VA).
. If the rating is in watts, multiply by 1.4 to obtain the VA requirement (this is the
typical relationship between watts and voltĆamperes ratings in most computing
equipment).
If the rating is in amperes or amperes max, multiply by the input voltage (200, 208,
220, 230, or 240 VAC) to obtain the VA requirement.
. Add all of the resultant VA ratings together to obtain the total load
requirements of the equipment to be protected.

Normal Mode
In Normal mode, incoming AC commercial power is filtered to reduce spikes and noise.
A portion of the utility power is automatically redirected to charge the battery, and the
battery charge condition is monitored. If the utility AC fails or falls out of specified limits,
the UPS automatically goes to OnĆBattery mode. The UPS automatically returns to
Normal mode when the utility power returns to within specified limits.
If Automatic Bypass is enabled and the utility goes out of specified limits, the Normal
indicator flashes and Bypass is not available.
On-Battery Mode
In OnĆBattery mode, the battery system provides DC power that is converted to
conditioned AC by the UPS. Depending upon the battery capacity, the system operates
in the OnĆBattery mode until the battery is fully drained. Output power is then no longer
available to the load. If incoming power returns within specified parameters, the UPS
automatically returns to Normal mode.
When the utility fails and the unit transfers to OnĆBattery mode, the Normal indicator
goes off, the Battery indicator illuminates, and the alarm sounds. Press the Horn
Silence button to turn off the alarm. The Battery indicator flashes and the alarm sounds
again when the battery is almost discharged. When the battery reserves are depleted,
the Battery indicator goes off and the UPS no longer provides power.
Overload Mode
The Overload indicator illuminates when the system goes into an overload condition
due to one of the following conditions: overload current is between 106% to 124% of
rating for 10 minutes, 125% to 149% for 30 seconds, or greater than 150% of the output
current rating for 10 cycles. The alarm sounds. Push the Horn Silence button to turn off
the alarm. If the Bypass feature is disabled or not available, the unit shuts down. If
Bypass is enabled, the unit transfers to Bypass mode in an overload condition.
Bypass Mode
In the Bypass mode, the UPS transfers the critical load directly to the filtered utility
power, provided the bypass source is available. The transfer occurs due to one of the
following conditions:
Load current is between 106% to 124% of the rating for 10 minutes, 125% to 149%
for 30 seconds, or greater than 150% for 10 cycles. (The UPS attempts three
restarts.)
UPS internal temperature exceeds safe operating range. (The UPS does not
attempt a restart.)
UPS output falls out of the specified voltage limits. (The UPS does not attempt a
restart.)
Output real power exceeds specified limits. (The UPS does not attempt a restart.)
Load current inrush (surge) exceeds peak current capability. (The UPS
continuously tries to restart.)
When the unit is in Normal mode and automatically transfers to Bypass due to a load
current overload condition, the UPS attempts to return to Normal mode. If three
autoĆstart attempts fail (due to a load current) within a 10Ćminute period, the UPS
remains on Bypass. When the unit transfers to Bypass due to an overtemp, realĆpower
overload, or inverter failure, the UPS remains on Bypass and does not attempt a restart.
When a surge current causes the unit to transfer to Bypass, the UPS continuously tries
to restart.
To switch to Bypass (with Bypass Configuration switch enabled), hold the UPS Off
button for three seconds. The Normal indicator goes off and the Bypass indicator
illuminates.
If the alarm sounds when the UPS Off button is pressed, then Bypass is
not available. If the UPS Off button is pressed for three seconds with Bypass not
available, the UPS enters Load PowerĆOff mode.
If the Bypass mode was entered from Normal mode, wait approximately one minute
before trying to return to Normal mode. The UPS waits for internal voltages to bleed
down before proceeding to Normal mode of operation. Press the UPS On button once
to return to the Normal mode.
Load Power-Off Mode
To switch to Load PowerĆOff from Bypass mode, hold the UPS Off button for three
seconds. The alarm sounds while the UPS Off button is held, and the Bypass indicator
goes off when the bypass voltage is removed from the load. Press the UPS On button
once to return to Bypass mode.
If Bypass is not enabled or the Bypass indicator is blinking (indicating that Bypass is
not available), the UPS enters Load PowerĆOff mode from Normal mode. To switch to
Load PowerĆOff from Normal mode, hold the UPS Off button for three seconds. The
alarm sounds while the UPS Off button is held, and the Normal indicator goes off when
the voltage is removed from the load. The UPS waits for internal voltages to bleed
down before proceeding to Normal mode of operation. Press the UPS On button once
to return to the Normal mode.
Load PowerĆOff can also be entered by turning off (O) the output breaker.
Audible Alarm
An audible alarm sounds a pulsing tone when the UPS is in Overload or OnĆBattery
mode. When there is one minute or less of battery time remaining, a constant tone
sounds. The alarm also sounds a constant tone if the UPS is on battery and the
UPS battery is disconnected (battery breaker is open or battery disconnected).
Bypass Plus
The UPS Bypass Plus feature contains two features in one: Automatic Bypass and
Maintenance Bypass. The UPS Bypass Plus features are available only when the
Bypass Configuration switch is enabled; this switch is factoryĆconfigured according to
your order.
Bypass operation requires that input and output voltage, frequency, and phase
displacement are the same. If the UPS is operating as a voltage and/or frequency
converter, bypass must be disabled. See Final Configuration" on page 45.
Automatic Bypass
The UPS automatically transfers the protected equipment directly to the utility AC
power, provided the bypass source is available, when one of the following conditions is
true:
Load current is between 106% to 124% of rating for 10 minutes, 125% to 149% for
30 seconds, or greater than 150% for 10 cycles.
UPS internal temperature exceeds safe operating range.
UPS output falls outside of the specified limits of voltage.
Output real power exceeds specified limits.
Load current inrush (surge) exceeds peak current capability.

3 UPS Operations
When the unit is in Normal mode and automatically transfers to Bypass mode due to an
overload condition, the UPS attempts to return to Normal mode. After output
realĆpower overload failure or any other abnormal condition, return to Normal mode
must be done manually (system startup). The UPS remains in Bypass mode if three
autoĆstart attempts fail within a 10Ćminute period.
Maintenance Bypass
The Maintenance Bypass switch is located under the top cover of the UPS (see
Figure 10 on page 37). When activated, this switch allows for onsite servicing of the
UPS. Be sure that the output breaker is turned on ( I ).

Electrical Installation
Refer to your national and local electrical codes for acceptable external wiring
practices. Material and labor for the external wiring are customerĆsupplied. An external
protective device for the input source must be provided and sized for the currents
indicated on the UPS nameplates.
NOTE: Upstream protection must be coordinated with the load current requirements
under nominal as well as lowĆline and overload conditions. The recommended
input stream service protection is 60 amps.
The UPS must be grounded at the input terminal block to a singleĆpoint local or utility
earth ground. The ground conductor should be sized according to your national and
local electrical codes. In the United States, the output is a separatelyĆderived source.
If you are using remote batteries, a DC breaker suitable for branch circuit protection
is required. The DC breaker is customerĆsupplied and must be rated at 250V, 75A.
The maximum fault current from a remote battery cannot be more than 4500 amps.
