Assembling and Installation Method

■When mounting the power supply with screws, it is recommended that this be done as shown above . If other methods are used, be sure

the weight of the power supply is taken into account.

■Avoid the not allowed installation method as it gives excessive stress to the mounting holes.

■Do not block air flow of the built-in fan (terminal block and ventilation hole).

■If the power supply is used in a dusty environment, use an airfilter. Make sure air flow is not blocked.

■If the built-in fan stops, thermal protection will work and the outputwill stop.

■The life expectancy (R(t)=90%) of the built-in fan varies depending on the operating condition.

■In the hatched area, the specification of Ripple, Ripple Noise is different from other area.

■The ambient temperature should be measured 5 to 10 cm away from the power supply so that it won’t be influenced by the heat from the

power supply. Please consult us for more details.

■Make sure the temperature at point A and point B is less than the temperatures shown in Instruction Manual 3.

■The ambient temperature is defined as the temperature of the air (at the terminal block side) that the built-in cooling fan blows into the pow-

er supply. Please pay attention to the heat generated by the input and output wires. Please consult us for more details.
