Installation
EDR Series Installation
The EDR Series supports DIN rail mounting with specific ventilation clearance and orientation requirements for reliable operation.
01 / 06
Vertical Orientation Only
The appropriate mounting orientation is vertical — input terminals at the bottom and output terminals at the top. Upside-down, horizontal or table-top mounting is not allowed, as sufficient cooling will not be possible.
02 / 06
Ventilation Clearance
Always allow good ventilation clearances around the unit: 5 mm left and right, 40 mm above and 20 mm below, to prevent overheating.
03 / 06
TS35 DIN Rail Mounting
Admissible DIN rail: TS35/7.5 or TS35/15. Tilt the unit slightly rearwards, fit over the top hat rail, slide it downward until it hits the stop, press against the bottom for locking, then shake slightly to check the locking action.
04 / 06
FG Must Be Connected to PE
The FG (Frame Ground) terminal must be connected to PE (Protective Earth) for safety and to ensure proper EMC performance.
05 / 06
Operating Temperature Limits
Maximum operating temperature is 45°C for EDR-75-12; 50°C for EDR-75-24/48, EDR-120-12/24/48 and EDR-150-24. Do not install in high ambient temperature locations or near fire sources.
06 / 06
Pollution Degree 2 Environment
Install the unit only in a pollution degree 2 environment — typically dry, well-ventilated locations such as control cabinets. Do not install in places with high moisture or near water.
The EDR Series operates with free air convection cooling and requires adequate ventilation clearance. Do not install in orientations other than vertical, such as upside down, horizontal or table-top mounting.
Wiring & Terminal
EDR Series Wiring & Terminal
The EDR Series uses two terminal blocks: TB1 for input and TB2 for output. Use copper wire only and ensure all strands of each stranded wire enter the terminal connection and the screw terminals are securely fixed to prevent poor contact.
Terminal Pin Assignment
TB1 — Input Terminal
| Pin No. | Assignment |
|---|---|
| 1 | FG (Frame Ground) |
| 2 | AC/N or DC- |
| 3 | AC/L or DC+ |
TB2 — Output Terminal
| Pin No. | Assignment |
|---|---|
| 1, 2 | DC OUTPUT -V |
| 3, 4 | DC OUTPUT +V |
The FG pin must be connected to PE (Protective Earth). Both -V pins (1, 2) and both +V pins (3, 4) should be connected to their respective output wires to prevent excessive current stress on a single contact.
Wiring Specification
Recommended Wire
| AWG | Rated Current | Cross-section |
|---|---|---|
| 18 | 7 A | 0.8 mm² |
| 16 | 10 A | 1.3 mm² |
| 14 | 15 A | 2.1 mm² |
| 12 | 20 A | 3.3 mm² |
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. Use wires that can withstand temperatures of at least 80°C, such as UL1007.
Terminal Torque Setting
| Model | I/P | O/P |
|---|---|---|
| EDR-75 | 6.9 kgf-cm (6 Lb-in) | 6.9 kgf-cm (6 Lb-in) |
| EDR-120 | 10.35 kgf-cm (9 Lb-in) | 10.35 kgf-cm (9 Lb-in) |
| EDR-150 | 6.3 kgf-cm (5.5 Lb-in) | 8 kgf-cm (7 Lb-in) |
Recommended wire strapping length: 5 mm (0.197″). Recommended screwdriver: 3 mm, slotted type.
Fuse & Circuit Breaker (230V)
| Model | Fuse | C16 | D16 |
|---|---|---|---|
| EDR-75 | T3.15A/L250V | 4 | 9 |
| EDR-120 | T4A/L250V | 5 | 9 |
| EDR-150 | T4A/L250V | 5 | 8 |
Maximum number of EDR PSUs that can be connected to a circuit breaker at 230V. For continued protection against risk of fire, replace only with the same type and rating of fuse.
DC Output Voltage Adjustment
All EDR models include a front-panel DC output voltage adjustment potentiometer (+V ADJ). The rated output voltage can be adjusted via the front-panel adjuster. EDR-120 and EDR-150 also include a DC OK indicator LED. Output current and output wattage must not exceed the rated value on its specification.
The actual wiring should follow the wiring diagram provided in the EDR Series installation manual. Use copper wire only and ensure all strands enter the terminal connection securely.
Safety & Compliance
EDR Series Safety & Cautions
Read and follow all safety instructions before installing, wiring, maintaining or modifying the EDR Series power supply.
- Risk of electrical shock and energy hazard. All failure should be examined by a qualified technician. Do not remove the case of the power supply yourself.
- Connecting both the primary and the secondary sides together is not allowed — risk of electric arcs and electric shock (danger to life).
- Risk of burn hazard. Do not touch the unit in operation and shortly after disconnection.
- Risk of fire and short circuit. The openings should be protected from foreign objects or dripping liquids.
- The FG (Frame Ground) must be connected to PE (Protective Earth).
- Output current and output wattage must not exceed the rated value on its specification.
- Before commencing any installation, maintenance or modification work, disconnect the system from supply voltage. Make sure that inadvertent connection in circuit will be impossible.
- For continued protection against risk of fire, replace only with the same type and rating of fuse.
- For BSMI-certified models: flammability of V1 or above is required for surrounding equipment. Class A equipment should not be installed or used in a residential environment to avoid electromagnetic interference.
Note: Pollution Degree 2 applies where there is only non-conductive pollution that might temporarily become conductive due to occasional condensation. Generally refers to dry, well-ventilated locations, such as control cabinets.
