Fig. 2 The unit may degrade, or be damaged, when it is continuously used outside the shaded region, refer to the graph shown in Fig. 2. When the DC-UPS module is used with power supply of different ratings, user must follow power supply derating curve or whichever is lower. In order for the device to function in the manner intended, it is also necessary to keep a safety distance of 50mm above and below the device as well as a lateral distance of 20mm (for Vertical Mounting) or 50mm (for Horizontal Mounting) with adjacent units while the device is in operation. Depending on the surrounding air temperature and output load delivered by the power supply, the device can be very hot! If the device has to be mounted in any other orientation, please do not hesitate to contact info@deltapsu.com for more details. No power de-rating across the entire operating temperature range (-20C to +60C) Assembly & Installation The unit can be mounted on 35mm DIN rails in accordance with EN 60715. For Vertical Mounting, the device should be installed with Input / Output terminal block on the bottom. For Horizontal Mounting, the device should be installed with Input / Output terminal block on the left side. Each device is delivered ready to install. Mounting Dismounting Fig. 3.1 Mounting Fig. 3.2 Dismounting Snap on the DIN rail as shown in Fig. 3.1: 1. Tilt the unit upwards and insert it onto the DIN rail. 2. Push downwards until stopped. 3. Press against the bottom front side for locking. 4. Shake the unit slightly to ensure that it is secured. To uninstall, pull or slide down the latch with screw driver as shown in Fig. 3.2. Then slide the unit in the opposite direction, release the latch and pull out the unit from the rail. 7 All parameters are specified at 25C ambient unless otherwise indicated. www.DeltaPSU.com (September 2014, Rev. 01) TECHNICAL DATASHEET CliQ II DC-UPS Module 24V 40A / DRU-24V40ABN Safety Instructions - - - - - - - - - - 8 Vertical Mounting Horizontal Mounting When replacing batteries, only use the same type of batteries listed under the "Battery Input / Output Characteristics" section on Page 2. Proper disposal of batteries is required. Refer to the relevant local codes for disposal requirements. ALWAYS switch mains of input power OFF before connecting and disconnecting the input voltage to the unit. If mains are not turned OFF, there is risk of explosion / severe damage. If the orange status LED is on, this indicates a failure in the installation. In this case, do not turn on power supply while the battery is connected. Danger of explosion! To guarantee sufficient convection cooling, keep a distance of 50mm above and below the device as well as a lateral distance of 20mm (for Vertical Mounting) or 50mm (for Horizontal Mounting) to other units. Note that the enclosure of the device can become very hot depending on the surrounding air temperature and load of the power supply. Risk of burns! The main power must be turned off before connecting or disconnecting wires to the terminals! DO NOT insert any objects into the unit. Hazardous voltages may be present for up to 5 minutes after the input mains voltage is disconnected. Do not touch the unit during this time. The unit is a built-in unit and must be installed in a cabinet or room (condensation free environment and indoor location) that is relatively free of conductive contaminants. All parameters are specified at 25C ambient unless otherwise indicated. www.DeltaPSU.com (September 2014, Rev. 01) TECHNICAL DATASHEET CliQ II DC-UPS Module 24V 40A / DRU-24V40ABN Functions Relay Contacts Characteristics Max Relay Contact Rating DC BUS OK Charging Battery Discharge* Battery Fail Battery Reverse Polarity 24Vdc/Vac, 1.0A Relay Contact "DC OK" contact is closed when the DC input voltage is within 24-28V (10%) range or the battery voltage is within 23-28V range LED Indicator Green LED On Relay Contact "DC OK" contact is closed when the unit is in charging mode LED Indicator Green LED Flashing Relay Contact "Discharging" contact is closed when the unit is in buffering mode LED Indicator Orange LED Flashing Relay Contact "BAT Fail" contact is closed when the battery fails to function or battery voltage is less than 14V LED Indicator Red LED On Relay Contact "DC OK" contact is opened when the battery is in reverse polarity LED Indicator Orange LED On * With output current 3A to 40A.

The DC-UPS module will shut down and protect itself. Normal operation of the module can be resumed upon removal of fault. The DC-UPS module's overvoltage protection will be activated when DC input to the module exceeds the maximum specified input voltage. The unit shall shutdown and return to normal state when the OVP condition is removed. Short Circuit Protection Over Temperature Protection The module is protected in case of short circuit at customer system, in the event of short circuit the module will shut down and protect itself. Normal operation can be resumed upon removal of fault. In the event of a higher operating temperature at 100% load, the power supply will run into OTP when the operating temperature is beyond what is recommended in the de-rating graph. When activated, the output voltage will shut down and remain in off state until the temperature drops to its normal operating temperature as recommended in the de-rating graph. 11 All parameters are specified at 25C ambient unless otherwise indicated. www.DeltaPSU.com (September 2014, Rev. 01) TECHNICAL DATASHEET CliQ II DC-UPS Module 24V 40A / DRU-24V40ABN Others Delta RoHS Compliant Restriction of the usage of hazardous substances The European directive 2011/65/EU limits the maximum impurity level of homogeneous materials such as lead, mercury, cadmium, chrome, polybrominated flame retardants PBB and PBDE for the use in electrical and electronic equipment. RoHS is the abbreviation for "Restriction of the use of certain hazardous substances in electrical and electronic equipment". This product conforms to this standard. Conformal Coating The Protective Coating Technology Delta Electronics Group has designed the perfect dipping technique which penetrates everywhere including under device, and prevents leakage. The conformal coating dipping can be applied to PCBs or circuit board. The coating preserves the performance of precision electronic primarily by preventing ionizable contaminants such as salt from reaching circuit nodes, where the material slumps around sharp edges. This can be a problem especially in highly conversing atmosphere. 12 All parameters are specified at 25C ambient unless otherwise indicated. www.DeltaPSU.com (September 2014, Rev. 01) Mouser Electronics Authorized Distributor Click to View Pricing, Inventory, Delivery & Lifecycle Information: Delta Electronics: DRU-24V40ABN
