Product Usage Instructions

Installation

1. Ensure the DIN Rail UPS system is powered off.
2. Mount the DR-UPS40 module on DIN Rail TS35/7.5 or TS35/15 securely.
3. Connect the DC input within the specified voltage range (24-29V).
4. Connect the external battery as per the recommended configurations.

Operation

• The LED indicators will show the status of DC BUS OK, Battery Fail, and Battery Discharge.
• Monitor the relay contact signals for any warnings or alerts related to the battery.
• Utilize the built-in battery test function periodically to ensure proper battery operation.

Maintenance

• Regularly check the battery polarity protection to prevent any damage.
• Clean the module and ensure proper ventilation for cooling by free air convection.

FAQ

• Q: How often should I perform the battery test function?
• A: It is recommended to perform the battery test function at least once every month to ensure battery health.
• Q: What should I do if the Battery Fail LED is lit?
• A: If the Battery Fail LED is lit, check the external battery connection and voltage levels to troubleshoot the issue.

OTHERS

| MTBF| 1365.7K hrs min.       Telcordia SR-332 (Bellcore); 161.9K hrs min.       MIL-HDBK-217F (25℃)
DIMENSION| 55.5125.2100mm (WHD)
PACKING| 0.55Kg; 20pcs/12Kg/1.49CUFT
NOTE| 1.  All parameters NOT specially mentioned are measured at rated load and 25℃ of ambient temperature.

2.  Battery failure will only function in UPS mode with the battery connected. Every 25 seconds, the unit will send out a test signal through the “Battery Fail” relay contact and LED indicator once the battery fails.

3.  The power supply is considered a component that will be installed into the final equipment. All the EMC tests are been executed by mounting the unit on a 360mm*360mm metal plate with 1mm of thickness. The final equipment must be re- confirmed that it still meets EMC directives. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies.”

4.  Battery charging will be in progress when DC input > battery voltage.

5.  DR-UPS40 will be in operation when DC input is applied at the beginning.

6.  The ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitudes higher than 2000m(6500ft).
