Introducon
NDR is a DIN rail power supply series with an economical price and slim design. Like other Mean Well DIN series, s
they can be mounted on a TS35 Standard DIN rail.
Installaon
( )1 Always allow good venlaon clearances, 5mm le and right, 40mm above and 20mm below, around the unit
in use to prevent it from overheang. Also a 10-15 cm clearance must be kept when the adjacent device is a
heat source.
( )2 The appropriate mounng orientaon for the unit is vercal, the input terminals the bottom and output on at
the top. Mounng orientaons other than that, such as upside down, horizontal, or table-top mounng, is not
allowed.
( )3 Use copper wire only, and recommended wires are shown as 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 connecon and the screw terminals are
securely xed to prevent poor contact. If the power supply possesses mul-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 m (0.197 . is 5m ”)
( )6 Recommended screwdriver is 3 , sloed type.mm
