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.

AWG 18 16 14 12 10 Rated Current of 6A 6-10A 13-16A 16-25A 25-32A Equipment (Amp) Cross-section of 0.75 1.00 1.5 2.5 4 Lead(mm2 ) 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. （3）Use copper wire only, and recommended wires are shown as below.

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 for TDR-480/960, 85°C for TDR-240.

（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.

Installation Manual 8 Suggested fuse and maximum number of the unit that can be connected to a circuit breaker at 400V are 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 (TDR-480 & TDR-960). 2 phases on a 3-phase-4 wire wye (star) operation possible in connecting L1, L3, FG or L2, L3, FG (TDR-240). 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 1 Tilt the unit slightly rearwards. 2 Fit the unit over top hat rail. 3 Slide it downward until it hits the stop. 4 Press against the bottom for locking. 5 Shake the unit slightly to check the locking action. 12 For other information about the products, please refer to www.meanwell.com for details. 1 2 3 4 "Click" Model Fuse Circuit breaker C16 D16 TDR-240 T4A/H500V 19 19 TDR-480 T4A/H500V 15 15 TDR-960 T6.3A/H500V 7 7

Installation Manual 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 are 50°C for TDR-480/960, 60°C for TDR-240, 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 risquй d’incendie, remplacer par un fusible de mкme type et de memes caractйristiques 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.
