Safety Instrucons And Baery Care
Safety Instrucons
• For Parallel System installaon please refer to TX90 6kVA & 10kVA Parallel System Installaon Guide
• Due to small leakage currents generated by the EMI lter in the UPS it is necessary to double check that
the ground wire of the UPS is properly grounded before connecng the UPS to the AC mains.
• To ensure safety in all applicaons where a UPS is hard wired to the electrical supply, ensure that the sys-
tem is installed by a qualied electrical contractor.
• The UPS has its own internal energy source (baery). Should the baery be switched on when no AC
power is available there could be voltage at the output terminals.
• Make sure that the AC ulity outlet is correctly grounded.
• Do not open the case as there are no serviceable parts inside. Opening the case voids the warranty.
• Do not try to repair the unit yourself; contact your local supplier. Repairing the unit yourself voids the war-
ranty.
• Please make sure that the input voltage of the UPS matches the supply voltage.
• Use a cered input power cable with the correct plugs and sockets for the appropriate system voltage.
• To prevent any overheang of the UPS keep all venlaon openings free from obstrucon, and do not
store things on top of the UPS. Keep the UPS 30 cm away from the wall.
• Ensure that the UPS is installed within the proper environmental range. (0-40°C and 0-90% non-condens-
ing humidity)
• Do not install the UPS in direct sunlight. Your warranty may be void if the baeries fail.
• Install the UPS indoors as it is not designed for installaon outdoors.
• Dusty, corrosive and salty environments can damage any UPS.
• Install the UPS away from objects that give o excessive heat and areas that are excessively wet.
• If liquids are spilled onto the UPS or foreign objects dropped into the unit the warranty will be null and
void.
• The baery will discharge naturally if the system is unused for a long period of me.
• The UPS should be recharged every 2-3 months if unused. If this is not done then the warranty will be
null and void. When installed and being used the baeries will be automacally recharged and kept in top
condion.
• Do not install the UPS in an environment with sparks, smoke or hazardous gas.
• Make sure the UPS is completely turned o when transporng it. It might cause electrical shock if the
output is not cut completely.
• The UPS includes a Maintenance Bypass Switch. Please follow the procedures strictly when switching on
or o the Maintenance Bypass Switch.
• The UPS oers a CVCF (Constant Voltage Constant Frequency) seng funcon.
1. For correct seng and wiring please contact with your local ulity agent.
2. Do not set it yourself or your warranty will be void.
• This UPS has been designed and constructed to protect your assets from the wide range of power aberra-
ons experienced on ulity power lines today. It is your insurance for a reliable, clean and stable voltage
supply. It is worth taking care to install the system correctly and to have it maintained correctly by your
local dealer.
• SAVE THESE INSTRUCTIONS. This manual contains important instrucons that should be followed during
installaon and maintenance of the UPS and baeries.
• The UPS is intended for installaon in a controlled environment.
• CAUTION: A disconnect switch must be provided by others for the AC output circuit. To reduce the risk of
re connect only to a circuit provided with branch circuit over-current protecon for 30 amperes for 6kVA
(See below for 10 kVA details) rang in accordance with the Naonal Electric Code, ANSI/NFPA 70.

current protecon for 40A for 6kVA and 60A for 10kVA rang in accordance with the Naonal Electric
Code, ANSI/NFPA 70.
• Install the UPS so that it is not likely to be contacted by people.
• The maximum ambient operang temperature is 40°C or equivalent.
• Units are considered acceptable for use in a maximum ambient 40°C.
• Servicing of baeries should be performed or supervised by personnel knowledgeable about baeries and
the required precauons.
• When replacing baeries, replace with the same type and number of baeries or baery packs.
• CAUTION – Risk of re hazard, UPS can be used with four Baery Cabinets.
• CAUTION - RISK OF EXPLOSION IF BATTERY IS REPLACED BY AN INCORRECT TYPE. DISPOSE OF USED BAT-
TERIES ACCORDING TO THE INSTRUCTIONS.
• CAUTION - Do not dispose of baeries in a re. The baeries may explode.
• CAUTION – Do not open or mulate baeries. Released electrolyte is harmful to the skin and eyes. It may
be toxic.
• CAUTION– A baery can present a risk of electrical shock and high short circuit current. The following
precauons should be observed when working on baeries:
1. Remove watches, rings, or other metal objects.
2. Use tools with insulated handles.
3. Wear rubber gloves and boots.
4. Do not lay tools or metal parts on top of baeries.
5. Disconnect charging source prior to connecng or disconnecng baery terminals.
6. Determine if baery is inadvertently grounded. If inadvertently grounded, remove source from
ground. Contact with any part of a grounded baery can result in electrical shock. The likelihood
of such shock can be reduced if such grounds are removed during installaon and maintenance
(applicable to equipment and remote baery supplies not having a grounded supply circuit).
Baery Care
If the UPS is unused for an extended period of me it must be stored in a moderate climate. The baeries should
be charged for twelve hours every three months by plugging the UPS power cord into a wall receptacle and turn-
ing on the input breaker on the front panel. Repeat this procedure every two months under a high-temperature
environment.

Product Introducon
General Characteriscs
• True online architecture connuously supplies your crical device with stable, regulated, transient-free,
pure-sine-wave AC power.
• 20 kHz PWM sine-wave topology yields excellent overall performance. The high crest factor of the inverter
handles all high-inrush current loads without a need to upgrade the power rang.
• The mul-funconal LCD/LED panel displays various states of the UPS. The LED display shows the UPS
working status, ulity status and abnormal status. The LCD display shows input/output voltage, frequency,
load status, inner cabinet temperature, and abnormal phenomena.
• To protect the unit from overloading, it automacally switches to bypass mode in 160 seconds at 100-
105% load, or 40ms if loading is at 105 ~150% of rang. In case of overloading at 150% of rang, it switches
to bypass mode immediately. It will automacally switch back to inverter mode once the overload condi-
on ceases.
• Should the output become short-circuited, the UPS cuts the output automacally unl the short-circuit
situaon is removed manually.
• Should the unit become overheated, the internal thermal switch will detect the heat and switch to bypass
mode and vice versa.
• The fully digitalized control circuit built into the UPS allows upgrading the funconality of the UPS as well
as reaching a high-level of protecon of the UPS. Powerful communicaon capability enhances its ability
for remote control and monitoring.
• Maintenance-free, sealed baeries minimize aer-sales service.
• The maintenance bypass switch provides an easy and safe troubleshoong or maintenance funcon when
the ulity is normal.
• Providing four dierent working modes (Normal, ECO, CF50 and CF60) it may be used in a wide variety of
applicaons.
• The DC-start funcon ensures the start-up of the UPS during power outages.
• A revoluonary baery management circuit analyzes baery discharging status to adjust the baery cut-
o point and extend baery life.
• The intelligent, temperature-controlled fan may not only extend the life of the fan but also reduce noise
because of sudden fan spin. This helps keep your oce quiet and comfortable.
• When the UPS is out of order you can read the possible reason directly from the LCD screen, which re-
duces unnecessary repairs.
• When the UPS is operated in CF50 or CF60 mode, the recommended load connected shall be 75% of rated
capacity if the input voltage is 176-280 VAC and 50% of rated capacity if the input voltage is 160-280 VAC.

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.

Viewing the UPS Default Sengs
• Aer the UPS completely starts up, press the (funcon) key to change the LCD display to gure Q1.
Q1
Buzzer “On”. Use the key to toggle the seng and then save.
Q2
Buzzer “O”
• Press the key to scroll through the UPS sengs. The LCD will display in sequence gure Q1 (buzzer) →
gure R (Self-test) → gure S (Bypass Voltage Windows) → gure T (Output Frequency Synchronizaon
Window) → gure U (Inverter Output Voltage) → gure V (UPS Operaon Mode) → gure W (Output Volt-
age Micro Tune Value) → gure X (UPS Id) → gure Y (Parallel funcon status).
• Buzzer and Self-test can only be changed in this mode while the UPS is on. All other sengs must be
changed while the inverter is o in this mode. See Changing the UPS Default Sengs on page 22.
• Default sengs shown below.
