Safety Guidelines

Prohibitions

1. Non-professionals are prohibited to install or commission the UPS alone.

2. As hazardous voltages are present within the UPS, only an Emerson technician or an Emerson-authorized technician is permitted to open it. Failure to observe this could result in electric shock risk and invalidation of any implied warranty.

3. Never dispose of the battery in a fire, as it may explode and jeopardize personnel safety when exposed to flame.

Matters needing attention

1. The standard UPS has its own energy source, external battery, therefore, the output terminal of the UPS may carry live voltage even when the UPS is not connected to the AC mains.

2. Before moving or re-wiring the UPS, please disconnect the mains source and make sure the UPS is completely shut down. Or else, the output terminal may carry live voltage, thus presenting electric shock risk.

3. To ensure human safety and normal operation, the UPS must be solidly and adequately grounded before use.

4. The operating environment and save method affect the UPS lifetime and reliability. It is advisable not to use the UPS for long in the following environments:

Places where the temperature and relative humidity are outside the specifications (temperature:

0°C ~ 40°C, relative humidity: 5% ~ 95%)

Places in direct sunlight or near heat source

Places subject to vibrations or shocks

Places which are dusty, strewn with corrosive substances or salts, or where flammable gases

are present

5. Please keep the air inlet and outlet unobstructed. Poor ventilation will increase the internal temperature, which will shorten the lifetime of the UPS components, hence that of the UPS.

6. Liquid and other irrelevant objects are strictly prohibited inside the UPS.

7. In case of fire, use dry chemical fire extinguisher to put out the fire. Using foam fire extinguisher may cause electric shock.

8. High ambient temperature shortens the battery lifetime. To ensure normal UPS operation and adequate autonomy time, the battery should be replaced periodically. Only Emerson-authorized technicians are permitted to replace the battery.

9. If the UPS will remain idle for a long period, it must be stored in a dry environment. The storage temperature should range between -20°C and +55°C for standard UPS (with internal battery), between -40°C and +70°C for extended UPS (with no internal battery.)

10. This equipment complies with IEC 61000-3-12 provided that the short-circuit ratio Rsce is greater than or equal to 250 at the interface point between the user’s supply and the public systerm. It is the

responsibility of the installer or user of the equipment to ensure, by consultation with the distribution network operator if necessary, that the equipment is connected only to a supply with a short-circuit ratio Rsce greater than or equal to 250.

11. The UPS output cable must be less than 10m.

Others

When the UPS is purchased to deliver power to the equipment listed below, please discuss with the distributor in advance about the applicability, settings, management and maintenance of the UPS, as these need special considerations during design and development.

Life-supporting medical apparatus

Figure 1-3 Operating principle diagram

1. The UPS is composed of mains input, I/O filter, rectifier/PFC, DC/DC boost, inverter, bypass, internal charger, battery input and UPS output.

2. When the mains is normal, close the bypass switch, and the internal charger will charge the battery. Before turning on the UPS, the output voltage is zero. After turning on the UPS, the electronic transfer switch connects the inverter to the load, the rectifier/PFC circuit rectifiers the mains power into DC power and feeds the DC power to the inverter. The inverter then inverts the DC power to pure sine wave AC power and feeds the AC power to the load through electronic transfer switch.

3. During mains failure, the rectifier/PFC circuit boosts the battery voltage and feeds it to the inverter. The inverter then converts it into pure sine wave AC power, and feeds the AC power to the load through electronic transfer switch.

4. After the mains recovers, the UPS will switch to Normal mode from Battery mode, the rectifier/PFC circuit rectifiers the mains power into DC power and feeds the DC power to the inverter, then electronic transfer switch feeds the DC power to the load.

1.5 UPS State And Operation Mode

The UPS state and operation modes include: Normal mode, Bypass mode, Battery mode, ECO mode and Fault state.

For the descriptions of indicators and control keys in this section, refer to Chapter 3 Operation And Display Panel.

1.5.1 Normal Mode

After installing the UPS, press and hold the ON/SILENCE key for over one second until a beep sound is heard. The UPS is started and then enters Normal mode or Battery mode.

When the mains input and output load are normal, the load is powered by the mains after processing of the inverter and the rectifier; meanwhile, the internal charger charges the battery. When the UPS is in Normal mode, the UTILITY indicator and INVERTER indicator are on.

1.5.2 Bypass Mode

Upon output overload or faults during the UPS operation, the UPS will switch to Bypass mode, the load is powered by the bypass AC source, which comes directly from the AC mains input; meanwhile, the internal charger charges the battery. When the UPS is in Bypass mode, the BYPASS indicator is on.

 Note

In the event of a mains failure or mains voltage outside the specifications (120Vac ~ 253Vac) when the UPS is in Bypass mode, the UPS will cease power for the load.

4 Chapter 1 Product Description

iTrust Adapt 6kVA UPS User Manual

1.5.3 Battery Mode

Upon mains failure, rectifier overload or mains voltage outside the specifications, the rectifier and internal charger will become inoperative, and the battery will power the load through the inverter. When the UPS is in Battery mode, the BATTERY indicator and INVERTER indicator are on, and the buzzer beeps every 3.3 seconds, notifying the user that the battery is powering the load.

 Note

1. In Battery mode, when the battery voltage is low, the buzzer beeps rapidly (once per second), and the corresponding measures must be done in time.

2. The battery had been fully charged before delivery. However, storage and transportation will inevitably cause some charge loss. Therefore, it is required to charge the battery for eight hours before putting the UPS into operation, so as to ensure adequate battery autonomy.

1.5.4 ECO Mode

In ECO mode, when the bypass voltage is 220Vac ±10% and the frequency is within 50Hz ± 2Hz, the load is supplied by the bypass AC source and the bypass indicator is on. You can use the ECO mode to power through bypass those loads that are insensitive to power supply quality, so as to reduce the power loss.

When the bypass voltage is normal, and the inverter is in no-load state, the load is supplied by the bypass AC source and the BYPASS indicator is on.

 Note

1. In ECO mode, if the bypass fails or bypass voltage is abnormal when the output is NOT overloaded, the UPS will switch to the Normal mode. However, if the bypass fails or bypass voltage is abnormal when the output IS overloaded, the UPS swill not switch to the Normal mode, but shut down the bypass.

2. In ECO mode, the efficiency of the UPS is up to 97%.

1.5.5 Fault State

Upon inverter failure or UPS over-temperature, the UPS will switch to Bypass mode when the UPS is in Normal mode, or shut down and stop the output when the UPS is in battery state. In UPS Fault state, the FAULT indicator will turn on, the buzzer will keep beeping and the corresponding indicator will blink.

 Note

In Fault state, if the bypass fails or bypass voltage is abnormal when the output is NOT overloaded, the UPS will shut down and be powered by the inverter, such as radiator over-hot. However, if the bypass fails or bypass voltage is abnormal when the output IS overloaded, the UPS will not switch to the inverter, but shut down the bypass.

2. Place the external switch to the OFF position if the UPS has an external battery.

After powering off the UPS, the UPS ceases output and the load is powered off.

4.7 Transferring UPS Between Operation Modes

In normal state, set the UPS to Normal mode. In the event of mains failure, the UPS will switch to Battery mode automatically and will not cease output. In the event of overload, the UPS will switch to Bypass mode and will not cease output. In the event of inverter fault and over-temperature in the UPS, the UPS will switch to work at fault state automatically.

4.7.1 Transferring UPS From Overload Protection To Bypass Mode

In the event of UPS load outside rated value and preset time, the UPS will switch to Bypass mode from Normal mode and send alarm rapidly (once per 0.5 second). At this point, the UPS outputs mains voltage, the alarm is not canceled till the extra load is removed. Five minutes later, the output will switch back to Normal mode automatically.

To protect the load and UPS, the time that the UPS switches from Normal mode to Bypass mode is not more than three within one hour due to overload. If more than three times, it will remain in Bypass mode and cannot switch back to Normal mode till one hour later.

4.7.2 Transferring UPS From Mains Failure To Battery mode

In the event of mains failure, the UPS will switch to Battery mode. If the UPS has been working till the battery is exhausted, the UPS will be shut down automatically. When the mains is normal, the UPS restarts automatically and switches to Normal mode. This restarting function is designed for unattended operation. If the UPS is shut down manually during battery state operation, the UPS should be restarted manually when the mains resumes.

Chapter 4 Operation Instructions 23
