operation of the UPS.

There is fear of damaging the connection device, since the changed voltage is outputted at the restart. And even if operating the switch during operation of the UPS, the output voltage cannot be changed.

If continuing to use the UPS that the battery life ended, there is fear of a liquid leak of battery, a smoking, and an ignition.

Replace the battery with one specified by our company and a new one.

If using the un-specified battery or mixing an old battery and a new battery, it becomes the cause of a liquid leak of battery, a smoking, an ignition, and the UPS failure and trouble.

When performing the rolling blackouts or when cutting off an input power supply, perform them after stopping the operation of the UPS, with reference to Chapter 4.2 "Turning off the UPS". The stop of operation can be confirmed by slow blink (in the cycles of approximately

1.6 sec.) of the RUN LED (green).

If cutting off an input power supply when the UPS is operating (the RUN LED is lighting), the UPS switches to the battery operation since it will be in the same state as a power failure. Performing such unnecessary battery operation leads to a shortening of a cycle of battery replacement.

Warning label



Warning labels are attached to the UPS.  Never remove the labels.

v

Caution for Use

Be careful about the following when using the UPS.

Important

Do not install and store the UPS in the following places:

 In an outdoor location  A place exposed to the elements  An extremely humid place and a dusty place  A place with corrosive gas or salinity  A place subjected to direct sunlight  A place near sparks or heating element  An extremely hot or cold place or place where the temperature fluctuates

greatly

 A place where vibration and a shock are added

Do not perform the battery check in succession.

When the battery check is performed, the UPS temporarily switches to the battery operation. If the battery check is performed in succession, there is fear of the battery deterioration or a shortening of a cycle of battery replacement since the battery becomes an over-discharge state.

If the UPS is not used for a long time, charge the battery every two months.

The battery is charged by operating the UPS. For the battery charging time, refer to Chapter 8.1 "Rated Specification". If the UPS is left without operating for a long time, there is a possibility that the UPS get unusable since the battery becomes an over-discharge state due to self-discharge.

This UPS is recyclable.

This UPS uses the small sealed lead storage battery. The small sealed lead storage battery uses expensive and rare resources. However, these precious resources are able to recycle. Cooperate in recycling without disposing of the used battery.

Do not block the vent hole and cooling fan or use the UPS in a stuffy place.

The vent hole and cooling fan are equipped in order to cool the inside of the UPS. There is a possibility that the inside and ambient temperature of the UPS may get out of the rated specification.

Replace the cooling fan periodically.

If continuing to use the UPS that the cooling fan life ended, there is a possibility that the inside temperature of the UPS may get out of the rated specification.

Do not use 5 to 9 of the switch of voltage setting.

It becomes impossible for the UPS to start up normally.

"Important" indicates caution about the use of the UPS.

Caution for Use

The permissible voltage between the input electric cable of the UPS and the ground is 250V AC.

If the voltage more than 250V AC is applied, the filter circuit of the input part may be damaged.

The permissible input surge voltage of the UPS is 5kV peak (1.2  50µs). However, if the model of the UPS is "-UC" and "-C", it is 2kV peak (1.2 

50µs).

If the surge voltage more than 5kV peak ("-UC" and "-C" are 2kV peak) is applied, the filter circuit of the input part may be damaged.

The input voltage of the UPS is 160 to 288V AC.

When input voltage is different from the rated specification (400V AC etc.), install a transformer at the outside of the UPS to convert voltage. If the voltage more than the range of the input voltage is applied, the UPS may be damaged.

Pay attention to an input voltage.

This UPS can operate up to 288V AC. However, an input voltage of the general device is 200V AC ±10%. Therefore, if switching to the bypass operation when applying the voltage of 220V AC to the UPS, the voltage exceeding specification is applied to the connection device. Adjust the input voltage to the specification of connection device.

Do not apply single-line grounding on the output side.

Between the input and output of the UPS is not insulated. Therefore, do not apply single-line grounding on the output side. There is fear of becoming the cause of the trouble of connection device by noise or the failure.

When connecting the UPS to the electrical power equipment with the earth leakage breaker, select the earth leakage breaker not to trip due to current leakage.

When connecting the UPS to the electrical power equipment with the earth leakage breaker, select the earth leakage breaker in consideration of total number of current leakage of the UPS plus current leakage of the connection device.

When connecting the UPS to a three-phase power supply system, be sure to connect the grounding phase of the three-phase power supply system to the electrode of a grounding side of the AC input of the UPS.

If connecting to an un-grounding power supply, there is fear of becoming the cause of the malfunction.

Pay attention to an input voltage.

This UPS can operate up to 288V AC. However, an input voltage of the general device is 200V AC ±10%. Therefore, if switching to the bypass operation when applying the voltage of 220V AC to the UPS, the voltage exceeding specification is applied to the connection device. Adjust the input voltage to the specification of connection device.

Do not apply single-line grounding on the output side.

Between the input and output of the UPS is not insulated. Therefore, do not apply single-line grounding on the output side. There is fear of becoming the cause of the trouble of connection device by noise or the failure.

The UPS should be connected to ground. (more than class D grounding) When connecting to an input power supply, connect the grounding wire to the ground terminal.

There is fear of an electric shock.

3.2 Connecting the Cable

Preparation before connecting the cable



Important

When connecting the UPS to the electrical power equipment with the earth leakage breaker, select the earth leakage breaker not to trip due to current leakage.

When connecting the UPS to the electrical power equipment with the earth leakage breaker, select the earth leakage breaker in consideration of total number of current leakage of the UPS plus current leakage of the connection device.

When connecting the UPS to a three-phase power supply system, be sure to connect the grounding phase of the three-phase power supply system to the electrode of a grounding side of the AC input of the UPS.

If connecting to an un-grounding power supply, there is fear of becoming the cause of the malfunction.

When using a generator temporarily during the rolling blackouts, use a generator satisfying the following specification.

If connecting a generator not satisfying the following specification to the input part of the UPS, there is a possibility of becoming the cause of the malfunction or damage of the UPS.

 Voltage regulation: depend on the input specification of the connection

device

 Frequency variation: within rated frequency ± 5% (frequency does not

change rapidly)

 Voltage waveform distortion: within 5%  Voltage zero-cross condition: Zero-cross must not occur twice or more in 1

5.3 Inspecting the Battery (Battery Check)

Inspection of the battery is performed using a battery check function. There are two kinds of battery check functions, an automatic check and a manual check. The manual check is not necessary ordinarily since automatic check is performed while the UPS is operating. Automatic check is performed in the following cases:

 When the operation of UPS is started up  Every two weeks in an operation continuation state  When the UPS has switched to the normal operation from the bypass operation

Perform manual check in the following cases:

 When a warning beep sounds due to the abnormalities in a battery  When performing the battery check other than the automatic check

Important

Do not perform the battery check in succession.

When the battery check is performed, the UPS temporarily switches to the battery operation. If the battery check is performed in succession, there is fear of the battery deterioration or a shortening of a cycle of battery replacement since the battery becomes an over-discharge state.

Remarks

The UPS became the failure state and switched to the bypass operation. Evacuate important connection device from the UPS. In this state, even if an input power failure occurs, the battery operation cannot be performed. Confirm ambient temperature and ventilation, and press the RESET switch on the front of the UPS for approximately 3 seconds after approximately 10 minutes have passed. If there is no problem, the UPS will return to the normal operation (No.1). If the ALARM LED does not go out or lights up again, even after the above operation is performed, contact an agent from which you purchased the UPS or a maintenance company. Abnormalities have occurred in the cooling fan. If this state continues for approximately 2 minutes or the inside temperature of the UPS rises, the UPS will become the

failure state of No.4. The UPS has been switched to the bypass operation manually. In this state, even if an input power failure occurs, the battery operation cannot be performed.

Since the abnormalities occur at an

input power supply, the UPS

cannot be started up.

Stop the UPS once, and restart after

confirming that an input power

supply is within the range of the

following conditions.

Input voltage: 160 to 288V AC

Input frequency: 47.5 to 52.5 Hz

or 57 to 63 Hz

Since the capacity of the

connection device exceeded the

rated value and the UPS became

the overload state, the UPS has

switched to the bypass operation

automatically. Reduce the capacity

of the connection device to less

than the rated value of the UPS. If

the capacity of the connection

device become below the rated

value, the UPS will return to the

normal operation (No.1). In the

state of the continuation of

During the bypass operation, the capacity of the connection device exceeds the rated value. Reduce the capacity of the connection device to less than the rated value of the UPS. In this state, even if pressing the bypass switch (pressing the RESET switch and the BATT CHECK switch for approximately 3 seconds simultaneously), the UPS will not return to the normal operation (No.1). During the battery operation, the capacity of the connection device exceeds the rated value. Reduce the capacity of the connection device to less than the rated value of the UPS. If this state continues for 100 seconds, the UPS will stop. Evacuate important connection device from the UPS. Since the UPS continued to be used even after the capacity of the connection device had exceeded the rated value of the UPS, the UPS stopped. Reduce the capacity of the connection device to less than the rated value of the UPS, and restart the UPS. Since the abnormalities occurred at an input power supply, the UPS started to supply the electric power to the connection device from the battery. It is not necessary to deal with it especially. If an input power supply returns, the UPS will return to the normal operation (No.1) automatically. The battery voltage has dropped since the battery operation continued. In the rated load, the battery operation will be completed approximately 2 minutes later. Evacuate important connection device from the UPS. If an input power supply returns, the UPS will return to the normal operation (No.1) automatically. The battery check is performed. At the manual battery check, a buzzer sounds at the start and end of the battery check. After the battery check is performed for approximately 5 seconds, the UPS will return to the normal operation (No.1) if there is no problem.

DANGER

■ Risk of electric shock Do not touch uninsulated battery terminal.

WARNING

■ Risk of electric shock

・Do not remove the cover for any reason. There are no user-serviceable parts

inside the UPS. Refer servicing to qualified service personnel.

CAUTION

■Don’t use this equipment in life support applications where failure of this

equipment can reasonably be expected to cause the failure of the life support equipment or to significantly effect its safety or effectiveness.

■Risk of electric shock

・Battery and cooling fan replacement should be performed only authorized

servicing personnel.

・The UPS has an internal energy source (the battery). The output may be

energized when the unit is not connected to an AC power line.

・Terminal marked “PE(G)” is intended for connection of the Protective

Earthing (Grounding) conductor(s). This earth connection is essential before connecting supply conductors. Also ensure the reliability of this connection during any servicing, including connection of protective earthing (grounding) conductors to the output (load).

・Capacitor stores hazardous energy. Do not remove cover until 7 minutes

after disconnecting all sources of supply.

・For M-UPS050AD2B, 2 pole circuit breaker is not provided on this UPS. If

this UPS installs, removes or does any services, for disconnecting all sources of supply, be off the external input circuit breaker.

■For ALL Models, to reduce the risk of fire,

・

Need to provide External Disconnect / Overcurrent Protective Device for the AC input and the AC output. -for example ,an UL Listed branch circuit breaker with suitable ratings could provide both functions (disconnect and overcurrent protection).

・

Suitable rating of input and output circuit breakers are shown in Table1 and Table2.

■Risk of explosion if battery is replaced by an incorrect type. Dispose of

used batteries according to the instructions.

■Do not dispose of batteries in a fire. The batteries may explode.

■Do not open or mutilate batteries. Released electrolyte is harmful to the

skin and eyes. It may be toxic.

8.2 Additional Description for UL Type

■A battery can present a risk of electrical shock and high short-circuit

current. The following precautions should be observed when working on batteries:

a) Remove watches, rings, or other metal objects. b) Use tools with insulated handles. c) Wear rubber gloves and boots. d) Do not lay tools or metal parts on top of batteries. e) Disconnect charging source prior to connecting or

disconnection battery terminals.

f) Determine if battery is inadvertently grounded.

If inadvertently grounded, remove source from ground. Contact with any part of a grounded battery can result in electrical shock. The likelihood of such shock can be reduced if such grounds are removed during installation and maintenance (applicable to equipment and remote battery supplies not having a grounded supply circuit).
