USER MANUAL 508360 Intellinet
NDR is a DIN rail power supply series with an economical price and slim design. Like other Mean Well's DIN series, they can be mounted on a TS35 Standard DIN rail.
- Installation
(1) Always allow good ventilation clearances, 5mm left and right, 40mm above and 20mm below, around the unit in use to prevent it from overheating. Also a 10-15 cm clearance must be kept when the adjacent device is a heat source.
(2) The appropriate mounting orientation for the unit is vertical, the input terminals at the bottom and output on the top. Mounting orientations other than that, such as upside down, horizontal, or table-top mounting, is not allowed.

Pure electrical circuit lines without any symbols(3) Use copper wire only, and recommended wires are shown as below.
| AWG | 18 | 16 | 14 | |
| Rated Current of Equipment (Amp) | 7A | 10A | 15A | 20A |
| Cross-section of Lead( mm^2 ) | 0.8 | 1.3 | 2.1 | 3.3 |
| 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. If the power supply possesses multi-output terminals, please make sure each contact is connected to wires to prevent too much current stress on a single contact.
(4) Use wires that can withstand temperatures of at least 80^ C, such as UL1007.
(5) Recommended wire strapping length is 5mm (0.197").
(6) Recommended screwdriver is 3mm, slotted type.

(7) The maximum operating temperature is 45^ C for NDR/EDR-75-12; 50^ C for NDR/EDR-75-24/48, NDR/EDR-120-12/24/48, NDR-240-24/48, NDR-480-24/48, please do not install the unit in places with high ambient temperature or near fire source.
(8) The FG (⊥) must be connected to PE (Protective Earth).
(9) Output current and output wattage must not exceed the rated value on its specification.
(10) Disconnect system from supply voltage:
Before commencing any installation, maintenance or modification work: Disconnect your system from supply voltage. Make sure that inadvertent connection in circuit will be impossible!
Note.1: Pollution Degree 2 applies where there is only non-conductive pollution that might temporarily become conductive due to occasional condensation. Generally refer to dry, well-ventilated locations, such as control cabinets.
