 Introduction
DR with class II is a double insulated DIN rail power supply series, meaning it is ungrounded. 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 for DR-15, the input terminals on the right and output on the left for DR-30, DR-60, and DR-100.
Mounting orientations other than that, such as upside down, horizontal, or table-top mounting, is not
allowed.
（3）Use stranded 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 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.
