M Ounting Method; Wiring Method - TDK-Lambda CUS350M Installationsanleitung

Forced air cooling condition:
Minimum air velocity: 1.5m/s (Measured at components side of PCB, air must flow through component side)

5-4. M ounting Method

(1) The maximum allowable penetration for screw into chassis is 4mm.
(2) Recommended torque for mounting screw: M4 screw, 1.27N·m (13kgf · cm).
(3) Metal plate with minimum 1.5mm thickness is recommended as mounting plate.
(4) Keep enough space in the power supply surroundings and the upper area of component for convection cooling., as a reference for reliable thermal
design, keep the temperature of Heat Sink lower than 110
>5mm
(5) Rear mounting from bottom side with 4*M4 screws is recommended to comply the vibration and shock specification. Recommended torque for the
Mounting screw: M4 scres, 1.27N·m (13.0kgf · cm).
(6) Recommend to connect mounting hole to protective ground of system

6. Wiring Method

(1) The output and input cables shall be separated each other and twisted individually to improve noise sensitivity.
(2) Use all cables as thick and short as possible to made lower impedance.
(3) Noise can be reduced by attaching a capacitor to the load terminals.
(4) For safety and EMI considerations, connect between
firmly.
(5) Recommended torque for the terminal: M3 screw, 0.49N·m (5.0kgf · cm).
7. External Fuse Rating
Refer to the following fuse rating when selecting the external fuses that are to be used on input line. Surge current flows when line turns on.
Have to use slow-blow or time-lag type fuse, not fast-blow fuse. Fuse rating is considered by in-rush current value at line turn-on. Do not
select the fuse according to input current (RMS.) values under the actual load condition.
