(2) (3) Installation notes Technical data IMPORTANT SAFETY INSTRUCTIONS • Retain these instructions or go to www.deltapsu.com/manuals. This manual contains important safety instructions. • When replacing batteries, only use the same type of batteries listed under the “Recommended Batteries” section. • Proper disposal of batteries is required. Refer to the relevant local codes for disposal requirements. Delta DC-DC Power Supply DRU-24V10AC  Figure 1 (1) (4) 1. Safety instructions • Switch explosion! • 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!

• T and below the device as well as a lateral distance of 5mm to other units. • Please note that the enclosure of the device can become very hot depending on the ambient temperature and load of the unit. Risk of burns! • The terminals! • Do not introduce any objects into the unit! • Dangerous voltage present for at least 5 minutes after disconnecting all sources of power. • 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. • CAUTION: “FOR USE IN A CONTROLLED ENVIRONMENT” 2.

Mounting (Fig. 2) The unit can be mounted on 35mm DIN rails in accordance with EN60715. For Vertical Mounting, the device should be installed with Input/Output/Battery terminal block on the bottom. Each device is delivered ready to install. Snap on the DIN rail as shown in Fig. 2: 1. Pull the unit’s DIN rail latch DOWN. 2. Tilt the unit slightly upwards, hook the top end onto the DIN rail and push downwards until stopped. 3. Position the bottom front end against the DIN rail. 4. Push the unit’s latch DIN rail UP to lock. 4. Dismounting (Fig.

3) To uninstall, 1. Pull the unit’s DIN rail latch DOWN. 2. Tilt the bottom part of the unit out. 3. Push the unit up and pull out from the DIN rail. Typical Application Notes 6.1 Provide backup power during AC source interruption or failure 5. Connection The terminal block connectors allow easy and fast wiring.
