Installation Manual

Introduction

Enclosed type switching power supplies possess a metal or plastic case for covering their internal PCB and will be installed inside the case of the end system. Mean Well's enclosed type power supplies include 2 different groups of power supplies, with built-in fan and without built-in fan, depending on their rated power or design concept.

Installation

1. Before any installation or maintenance work, please disconnect your system from the utility. Ensure that it can't be re-connected inadvertently!
2. Keep enough insulation distance between mounting screws and internal components of power supplies. Please refer to case drawing on specifications to receive the maximum length of mounting screw.
3. Mounting orientations other than standard orientation or operate under high ambient temperature may increase the internal component temperature and will require a de-rating in output current. Please refer to the specification sheets to receive the optimum mounting position and information about the de-rating curve.
4. Fans and ventilation holes must be kept free from any obstructions. Also a 10-15 cm clearance must be kept when the adjacent device is a heat source.
5. Input and Output terminal specifications are provided in the following tables.
6. Torque can be various due to different material; please refer to the following charts for recommendations for aluminum and iron.
7. Recommended wires are shown in the table below. Note: Current each wire carries should be de-rated to 80% of the current suggested above when using 5 or more wires connected to the unit. Make sure that all strands of each stranded wire enter the terminal connection and the screw terminals are securely fixed to prevent poor contact.
8. Wiring: Wire color will vary by country; please refer to the table below for North America and European Harmonized standards. Ensure all wires are secured to prevent poor contact.
9. For other information about the products, please refer to www.meanwell.com for details.

Torque Recommendations

A. Recommended torque for aluminum

A. Recommended torque for aluminum (Metric Units)

B. Recommend torque for iron

B. Recommend torque for iron (Metric Units)

If above mentioned is not enough due to special application, Nylok Blue Patch screw is recommended, and extra torque can be added if needed.

Recommended Wires

Note: Current each wire carries should be de-rated to 80% of the current suggested above when using 5 or more wires connected to the unit. Make sure that all strands of each stranded wire enter the terminal connection and the screw terminals are securely fixed to prevent poor contact.

Wiring

The wire color will vary by country; please refer to the table below for North America and European Harmonized standards.

a) Connect the FG wire (green or green/yellow) of the power supply to PE (green or green/yellow); this step can be skipped when the unit is marked class II, ungrounded.

b) Connect the ACL wire (black or brown) of the power supply to Live (black or brown).

c) Connect the ACN wire (white or blue) of the power supply to Neutral (white or blue).

d) Make sure all wires are secured to prevent poor contact.

Wiring Diagram Description

The diagram illustrates a basic AC input connection for a Power Supply Unit (PSU). The input lines are labeled LIVE/HOT (Black or brown), NEUTRAL (White or blue), and PE (Green or green/yellow). These lines connect to the PSU's AC/L, AC/N, and FG terminals, respectively. A circuit breaker (CB) and a line connection (LINC) are shown in the path of the AC input to the PSU.

Warning / Caution

• Risk of electrical shock and energy hazard. All failure should be examined by a qualified technician. Please do not remove the case of the power supply by yourself!
• Please do not install power supplies in places with high moisture or near the water.
• Please do not install power supplies in places with high ambient temperature or near fire source. The maximum ambient temperature please refer to their specifications.
• Output current and output wattage must not exceed the rated values on specifications.
• The ground(FG) must be connected to earth ground.
• All MW's PSUs are designed in accordance with EMC regulations and the related test reports are available by request. Since they are component power supplies and will be installed inside system enclosure, when they are integrated into a system, the EMC characteristics of the end system must be re-verified again.
• This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (a) This device may not cause harmful interference, and (b) this device must accept any interference received, including interference that may cause undesired operation.
• For series of LRS, NES, PSP, PSPA, RD, RSP, RS, SE that certified with BSMI approvals, flammability of V1 or above is required for surrounding equipment and operation of this equipment in a residential environment could cause radio interference.
