Introduction
TDR series is the next generation of Mean Well DIN rail power supplies with three-phase or high input range, this
three-phase DIN unit not only has a slim design of 110mm in width but also possesses a high efficiency of up to
94.5%. 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.
（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 5mm (0.197”).
（6）Recommended screwdriver is 4mm, slotted type.
（7）The recommended torque setting for terminals is shown as below.

（9）The unit is capable of being connected between any 2 phases on a 3-phase-4-wire Wye (Star) connected
system.
（10）The unit is capable of dual phase operation, but that requires de-rating output current by at least 20%.
（11）Mounting Instruction：
Mount as shown in figure only, with input terminals down, or else sufficient cooling will not be possible.
Admissible DIN rail：TS35/7.5 or TS35/15
For rail fastening：
○
1Tilt the unit slightly rearwards.
○
2Fit the unit over top hat rail.
○
3Slide it downward until it hits the stop.
○
4Press against the bottom for locking.
○
5Shake the unit slightly to check the locking action.

Warning / Caution !!
（1）Risk of electrical shock and energy hazard. All failure should be examined by a qualified technician. Please do
not remove the case of the power supply by yourself!
（2）Risk of electric arcs and electric shock (danger to life). Connecting both the primary and the secondary sides
together is not allowed.
（3）Risk of burn hazard. Do not touch the unit in operation and shortly after disconnection!
（4）Risk of fire and short circuit. The openings should be protected from foreign objects or dripping liquids.
（5）The maximum operating temperature is 50°C for the power supply, please do not install the unit in places with
high ambient temperature or near fire source.
（6）Instructions for installation in a Pollution Degree 2 environment (Note.1).
（7）Please do not install the unit in places with high moisture or near the water.
（8）The FG ( ) must be connected to PE (Protective Earth).

（9）Output current and output wattage must not exceed the rated values 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!
（11）For continued protection against risk of fire, replace only with same type and rating of fuse.
Pour ne pas compromettre la protection contre les risqué d’incendie, remplacer par un fusible de même
type et de memes caractéristiques nominales.
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.
