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

Facilities such as lifts/elevators where adequate care has to be taken to avoid any fatal

eventuality endangering human life

Any other mission-critical equipment like the above

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.
