Mean Well XDR-E Series DIN Rail Power Supply User Manual

1. Introduction

The Mean Well XDR-E series is a range of DIN rail power supplies designed for industrial control applications. These units feature an economical price point and a slim design, making them suitable for various build-in equipment and indoor use scenarios, including audio/video, information, and communication technology equipment. They are designed to be mounted on a standard TS35 DIN rail.

2. Setup and Installation

2.1. Mounting Guidelines

• Ventilation: Ensure adequate ventilation clearances around the unit. Maintain at least 5mm on the left and right sides, 40mm above, and 20mm below. If an adjacent device is a heat source, maintain a 10-15 cm clearance.
• Orientation: The unit must be mounted vertically, with the input terminals positioned at the bottom and the output terminals at the top. Other orientations, such as upside down, horizontal, or table-top mounting, are not permitted as they can impede proper cooling.
• DIN Rail Compatibility: Compatible with TS35/7.5 or TS35/15 DIN rails.
• Mounting Procedure:
  1. Tilt the unit slightly rearwards.
  2. Fit the unit over the top hat rail.
  3. Slide it downward until it reaches the stop.
  4. Press against the bottom of the unit to lock it into place.
  5. Gently shake the unit to confirm it is securely locked.

2.2. Wiring Instructions

• Wire Type: Use copper wire only.
• Recommended Wire Specifications:

  AWG	Rated Current (Amp)	Cross-section ($mm^2$)
  18	7A	0.8
  16	10A	1.3
  14	15A	2.1
  12	20A	3.3

  Note: If connecting 5 or more wires to the unit, de-rate the current each wire carries to 80% of the suggested value.

• Wire Connection: Ensure all strands of each stranded wire fully enter the terminal connection. Securely fix the screw terminals to prevent poor contact. If the power supply has multiple output terminals, connect wires to each contact to prevent excessive current stress on a single contact.
• Wire Temperature Rating: Use wires capable of withstanding temperatures of at least 80°C (e.g., UL1007/1015).
• Wire Stripping Length: Recommended wire stripping length is 5mm (0.197 inches).
• Screwdriver: Use a 3mm slotted screwdriver.
• Terminal Types:

  Terminal Type	Usage
  Blank (Screw Terminal)	Insert the wire and tighten the screw.
  LA (Lever Actuated)	Open the lever, insert the wire, then press down on the lever.
  PI (Push In)	Insert the wire.

• DC OK Terminal:
  • Contact Ratings (max.): 30V/1A resistive load
  • Solid Wire: 1.5mm² max.
  • A.W.G: 24~16AWG
  • Usage: Insert the wire.

2.3. Terminal Torque Settings

For models with screw terminals, the recommended torque setting for both input (I/P) and output (O/P) terminals is 5.8 kgf-cm (5 Lb-in).

3. Operating Instructions

• Load Conditions: XDR-E series units can operate at full output load up to a maximum ambient temperature of 50°C. They can also operate with 75% load up to a maximum ambient temperature of 70°C. (Note: XDR-960E series operates with 70% load at a maximum ambient temperature of 70°C).
• Rated Values: Do not exceed the rated output current and output wattage specified in the product's specifications.
• Cooling: The unit utilizes natural air cooling. Ensure proper ventilation as described in the mounting guidelines.

4. Maintenance

4.1. Fuse Replacement

For continued protection against the risk of fire, replace fuses only with the same type and rating as specified for your model.

4.2. General Care

Keep the unit's ventilation openings clear of dust and debris to ensure optimal cooling performance.

5. Troubleshooting and Safety Warnings

5.1. Safety Warnings

• Electrical Shock & Energy Hazard: All failures should be examined by a qualified technician. Do not remove the case of the power supply yourself.
• Electric Arcs & Shock: Connecting both the primary and secondary sides together is strictly prohibited.
• Burn Hazard: Do not touch the unit during operation or shortly after disconnection, as surfaces may be hot.
• Fire & Short Circuit: Protect all openings from foreign objects or dripping liquids.
• Environment: Install the unit only in a pollution degree 2 environment. Avoid installing in places with high moisture, near water, or near fire sources.
• Disconnection: Always disconnect the system from the supply voltage before commencing any installation, maintenance, or modification work. Ensure inadvertent connection is impossible.
• Improper Use: If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired.
• Hot Surface: The product surface can become hot during operation; avoid touching it.
• Protective Earth (PE): The PE terminal must be connected to Protective Earth.
