Product Usage Instructions

• Removing the Power Supply from the DIN Rail
  • Position the power supply so that the hooks of the DIN rail mounting bracket hook onto the upper edge of the DIN rail.
  • Pull down and hold the spring-loaded latch of the DIN rail mounting bracket.
  • Rotate the power supply towards the DIN rail so that the DIN rail snaps into the mounting bracket.
  • Release the latch of the DIN rail mounting bracket to secure the mounting.
• Connecting Power Cords
  • Pull down and hold the latch of the DIN rail mounting bracket.
  • Press down the power supply slightly and rotate the bottom away from the DIN rail so that the bottom of the DIN rail mounting bracket is disengaged from the DIN rail.
  • Release the latch of the DIN rail mounting bracket and then lift the power supply to remove it from the DIN rail.

FAQs

• Q: What should I do if the LED indicates an overload protection state?
  • A: In the overload protection state where the LED is steady red and there is no power output, you should check and reduce the load on the power supply to resolve the issue. Once the load is within limits, the power supply will automatically recover.
• Q: How can I adjust the output voltage of the power supply?
  • A: To adjust the power supply’s output voltage, use the +V ADJ feature. Turning the adjuster clockwise increases the output voltage while turning it counterclockwise decreases the output voltage.

About the power supply

DG-240-5502 industrial power supply is a DIN-Rail-Mount AC-input and DC-output power supply designed for industrial Ethernet switches. It can be installed on a TS-35/7.5 or TS-35/15 DIN rail.

relay closes the contact.
2| OK| Relay pin 2| When the output voltage decreases to 35 ± 5 VDC, the relay opens the contact.
3| +V| DC output positive connection
4| -V| DC output negative connection

5

| +V ADJ| Voltage output adjusted. Turning the adjuster clockwise increases the output voltage. Turning the adjuster counterclockwise decreases the output voltage.
6| DC-OK (green) / Overload (red)| Voltage output status LED
7| Parallel Use / Single-Use| A switch that controls parallel use or independent use of the power supply.
8| L| AC input live wire connection
9| N| AC input neutral wire connection
10| Grounding| AC input PE wire connection

• The DC-OK relay detects the output voltage of the power supply. The maximum load that the DC-OK contact can bear is 30 VDC/1 A, 60 VDC/0.3 A, or 30 VAC/0.3 A.
• The parallel/single-use switch is factory set to the Parallel Use position. As a best practice, do not change the switch position.
• 1 When multiple power supplies are used in parallel, make sure the average output power of each power supply does not exceed 95% of the rated output power as a best practice.

Removing the power supply from the DIN rail

1. Position the power supply so that the hooks of the DIN rail mounting bracket hook onto the upper edge of the DIN rail.
2. Pull down and hold the spring-loaded latch of the DIN rail mounting bracket.
3. Rotate the power supply towards the DIN rail so that the DIN rail snaps into the mounting bracket.
4. Release the latch of the DIN rail mounting bracket to secure the mounting.

Connecting power cords

1. Pull down and hold the latch of the DIN rail mounting bracket.
2. Press down the power supply slightly and rotate the bottom away from the DIN rail so that the bottom of the DIN rai mounting bracket is disengaged from the DIN rail.
3. Release the latch of the DIN rail mounting bracket and then lift the power supply to remove it from the DIN rail.

• The power supply has power input and output terminals, used for connecting AC and DC power cords, respectively.
• The power cord wiring colour codes vary by country and region.
• The wire colours in the figure are for illustration only.

Connecting an AC input power cord

1. Insert the exposed PE wire into the ground terminal (Grounding) at the bottom of the power supply.
2. Insert the live and neutral wires into the live (L) and neutral (N) terminals, respectively.
3. Fasten the screws on the terminals to secure the wires.
   • High voltage is present on the AC input power wires. Make sure the AC power is cut off before connecting the AC input power wires.
   • Make sure no exposed part of an AC input power wire extends from the connector.

Connecting a DC output power cord

1. Connect the DC output power wires to the wiring terminals at the top of the power supply, with the positive wire to a positive terminal (+V) and the negative wire to a negative terminal (-V).
2. Fasten the screws of the terminals to secure the power wires.
   • Two positive terminals (+V) are provided for the positive output and two negative liiil terminals (-V) are provided for the negative output
   • Box Content: 1 x AC EXTERNAL POWER SUPPLY
   • Compatible with: SI 3100-8GP-4S.
