 Introduction
WDR series is a sort of DIN rail power supplies with high PFC capability and a wide input range, 180-550Vac. And
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 on the bottom, 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.
（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 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 7mm (0.275”).
（6）Recommended screwdriver is 3mm, slotted type.
（7）The recommended torque setting for terminals is shown as below.
