Read the following precautions before you install the UPS.
• This UPS contains its own energy source (batteries).
• The DC mains power must be turned off before connecting or disconnecting wires to the terminals.
• Use RED wire for (+) positive and BLACK for (-) negative wire connections.
• Make sure the wires do not touch to chassis during their connection.
• Always connect the DC mains input and load output wires first, then the UPS battery terminals labeled
(BAT +/-), and finally to the EBM.
• To reduce the risk of fire or electric shock, install this UPS in a temperature and humidity controlled, indoor
environment, free of conductive contaminants. Ambient temperature must not exceed 50°C ( 22°F). Do
not operate near water or excessive humidity (95% max).
• To comply with international standards and wiring regulations, the total equipment connected to the
output of this UPS must not have an earth leakage current greater than .5 milliamperes.
• To guarantee sufficient convection cooling, please keep a clearance of 50mm above, 80mm below, and
0mm lateral distance of between devices.
• Note that the enclosure of the device can become very hot depending on the ambient temperature and
load of the power supply. Risk of burns!
• Do not introduce any objects into the unit.
• The UPS and EBM unit should be installed in minimum IP54 rated enclosure.
• The units must be installed in a cabinet or room (condensation free environment and indoor location) that is
relatively free of conductive contaminants.
This UPS contains LETHAL VOLTAGES. All repairs and service should be performed by AUTHORIZED
SERVICE PERSONNEL ONLY. There are NO USER SERVICEABLE PARTS inside the UPS.
• For use in a controlled environment.
• Batteries can present a risk of electrical shock or burn from high short-circuit current. Observe proper
precautions. Servicing should be performed by qualified service personnel knowledgeable of batteries and
required precautions. Keep unauthorized personnel away from batteries.
• Proper disposal of batteries is required. Refer to your local codes for disposal requirements.
• Never dispose of batteries in a fire. Batteries may explode when exposed to flame.

To Start the UPS:
. Ensure that the UPS input and output wiring are connected and that the correct voltage is being supplied
to the UPS. See 3.2 DIN24240DC / DIN24480DC Input Wiring.
2. Verify that the external batteries are connected. See 4.2 Extended Battery Module Wiring .
3. Press the power ON/OFF button on the front of the UPS for three seconds.
NOTE As long as live 24V DC is supplied to the UPS input terminals, the DC output terminals
will be live in Bypass and Line operation modes.
4. Verify that the green power LED illuminates solid indicating the UPS is operating normally and any loads
are powered and protected.
5. Check the UPS front panel to verify that there are no active faults. Do not proceed until all active faults are
cleared see 8. Trou leshooting .

To shut down the UPS:
. Press and hold the UPS ON/OFF button for three seconds. The UPS then transfers to the OFF mode and
the green power LED turns off.
If you are planning on removing the UPS or EBM (if applicable) from the DIN rail ensure all sources of DC power
have been disconnected and properly isolated.

The UPS self test feature is preformed automatically when the UPS has access to acceptable line voltage. If
the battery voltage is less than 0VDC the unit will consider the battery as abnormal and fail the test. If the
battery voltage is above 0VDC the UPS will initiate a 6 second battery charge.
Once the UPS is turned on via the ON / OFF button if the battery voltage drops below 8VDC the battery will be
considered abnormal.

The Eaton DIN24240DC / DIN24480DC system is designed to provide years of trouble-free operation. Its
internal control system checks the batteries and inverter periodically to ensure reliable operation.
The Eaton DIN24240DC / DIN24480DC UPS and optional external battery cabinets do require some attention to
assure continued reliable service. Follow Eaton's recommended maintenance schedule, which includes:
• Check operating environment for clean, cool, dry conditions.
• Inspect and clean the area around the UPS
• Check the batteries.
For more information on preventive maintenance checks, contact your service representative

Ambient temperature range is - 5 °C to 40 °C (5 °F to 04 °F). It is recommended to charge the UPS for at least
8 hours, then store the UPS covered and upright in a cool, dry location. Remove accessories and disconnect
cables connected to the UPS to avoid unnecessary draining of the battery.
Extended Storage
During extended storage in environments where the ambient temperature is: — 5°C to +40 °C (+5 °F to + 04
°F), charge the UPS battery every three months.
