Introduction
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.
（

）
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.
Use copper wire only, and recommended wires are shown as below.
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.

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.
