Remarks:
1. When one of the Er06, EPO, Er23, Er24, Er28, Er32 ,or Er33 error message occurs, the UPS will have no
output and lock itself immediately.
2. If the bypass voltage is normal(within specs), but one of the Er01, Er02, Er03, Er05, Er13, Er14, Er20, Er22,
Er26, Er29 or Er30 error message occur, the UPS will transfer to Bypass loop and lock itself.
3. If the bypass voltage is normal(within specs), one of the Er04, Er08, Er09, Er10, Er11 or Er12 error message
occurs, the UPS will transfer to Bypass loop, then try to transfer back to Inverter mode automacally. If
the symptoms happen 4 mes in one hour, the UPS will lock itself; otherwise, the error messages and the
mes of the error messages will be clear and reset automacally.
4. If the Er16, Er17, Er21, Er27, Er31 or Er34 error message occurs, the inverter of the UPS will have no output
and the user is prohibited to turn on the UPS from the front panel.

Communicaon Port
The communicaon port on the UPS provides for RS-232 communicaon with the UPS soware to remotely moni-
tor the power and UPS status.
You may use oponal interface cards for Relay (Dry Contact) and SNMP. These cards may be used simultaneously.
The soware bundled with the UPS is compable with many operang systems such as Windows 98, 2000, ME,
NT and XP. For other applicaons such as Novell NetWare, Unix, or Linux please contact your local distributor for
a proper soluon.
When the oponal interface cards are used together with the onboard RS-232 port the EPO signals will get highest
priority, then the SNMP/WEB card, then the shutdown command at the relay card, and then nally the onboard
RS-232 port gets the lowest priority.

The Pin Assignments of true RS-232 are as follows (The connector is male):
Pin 3: RS-232 Rx

Installaon and Operaon
Carefully inspect the UPS for shipping damage before installaon. Retain the packing material for future use.
Unpacking
Standard package contents:
• Quick start guide
• User manual
• Upsilon 2000 soware CD
• (3) Output jumpers
• (4) Small Phillips head screws
• RS-232 cable
• Oponal skirt assembly including: (2) 22 3/4” side skirt, (2) 11.5” front and rear skirt, and (1) plasc skirt
Selecng Installaon Posion
Install the UPS in a proper environment to minimize the possibility of damage to the UPS and to extend the life of
the UPS. Please follow these requirements:
1. Keep at least 12 inches clearance from the rear panel of the UPS to the wall.
2. Keep at least 8 inches clearance from the rear panel of the External Baery Pack (EBP) to the wall. Refer to
the T90-EBP920, EBP940, EBP960 user manual for more details.
3. Do not block the air ow to the venlaon openings of the unit.
4. Ensure that the installaon site is not excessively hot or moist.
5. Do not place the UPS in an environment near dust, corrosive or salty material, or ammable objects.
6. Do not expose the UPS to the outdoors.

G2, N22, L22, N21, L23, L21: the terminals for UPS output, see below output opons for conguraon details
G2: the terminal for UPS output ground
Remarks:
1. The maximum current for each terminal is 30 Amps for 6 kVA, 50 Amps for 10 kVA.
2. The UPS is always a Single Input conguraon. The Dual Input conguraon is not used. The AC source can
be 208V or 240V landed to the L12 and N1 terminals.
3. Use No. 6 AWG, 75°C minimum copper wire and 23 lb-in Torque force when connecng to terminal block.
4. The transformer has two input voltage opons, 208V and 240V. If the input is congured at 208V but the
actual input is 240V, then the output voltages will boost up 15%.
Input Conguraon
208V input applicaons: 208V input with a 120/240V output is the default for these systems. This means the in-
verter output is programmed to 208V and the output transformer primary tap is set to the 208V seng. These are
the default sengs for this system. Please refer to output Opon 1 in this secon.
240V input applicaons: If the input voltage is 240V, the following steps must be performed to obtain a 120/240V
output with a 240V input.
1. With no AC applied to the unit, change the transformer primary tap from 208V default seng to 240V
shown below. Access to tap sengs is gained by removing the side covers.
TX90-6K Input Taps TX90-10K Input Tap Board
2. The UPS inverter output voltage must also be programmed to 240V. Refer to the Changing the UPS Default
Sengs secon for more details. Opon 1 below provides a 120/240V output with a 240V input.

Output Conguraon
All of the output opons shown below apply to 208V input systems and 240V input systems.
Opon 1: 120V/240VAC - THIS IS THE DEFAULT OPTION FOR ALL UNITS: Each branch max loading 50%. Please
note the jumpers between G2-L22 and L22-N21 for this opon.
Opon 2: 120V full capacity output. Please note the jumpers between G2-N22, N22-N21, and L22-L21 for this
opon. See below.

Start Up in Normal Mode
• Open the terminal block cover on the rear panel. Before starng the installaon make sure the wiring is
connected properly.
• Make sure the ulity input breaker and the UPS’ input breaker are in the “O” posion.
• Switch on the ulity input breaker on the distribuon panel and the UPS input breaker. Then the UPS will
start up. Green LEDs and show that the Ulity and Bypass inputs are normal. UPS will display rst gure
A1 and then gure B.
A1

• The UPS is now in Bypass Mode. It will proceed to self-test automacally. If no abnormal message appears
then the pre-startup of the UPS was successful and the charger begins to charge the baeries
• Press the UPS On switch for approximately three seconds. The Buzzer sounds twice and the LCD display
changes from gure B to gure C.
C
• The UPS is in self-test mode again. The LCD display will change from gure C to gure D, and the UPS will
remain in baery mode for approximately four seconds. Then the display will change from gure E1 to
gure F if the self-test was successful.

• If the self-test fails the LCD display will change from gure D to gure E2. Then an error code or error status
will appear on the screen.
• Your start-up operaon of the UPS is complete now. Make sure the UPS is connected to ulity and charging
at least 8 hours and the baeries are fully charged before connecng the device to be protected.
Start-up in Baery Mode (Cold Start)
• Make sure the UPS has at least one string (20 pcs) of baeries.
• Push the UPS On switch once for approximately 5 seconds to wake the UPS. The buzzer will sound
twice. The LCD display will change from gure A to gure G for approximately 15 seconds.
• Press the UPS On switch again for about three seconds unl the LCD display changes from gure G to
gure H. Then the UPS will be in self-test mode. The UPS may oer energy to the output in a minute, and
the LCD displays gure I. In case of failure in pushing the UPS On switch for 15 seconds, the UPS will auto-
macally turn o. You must then repeat steps.
