- *1 Output derating is required at 180 - 200VAC. Refer to “Derating”. 

- *2 The value is primary surge. The current of input surge to a built-in EMI/EMS Filter (0.2ms or less) is excluded. More than 3 sec. to re-start. 

- *3 Measured by 20MHz oscilloscope or Ripple-Noise meter (equivalent to KEISOKUGIKEN : RM104). Please refer to the instruction manual 1.7. 

- Sound noise may be generated by power supply in case of pulse load.

## **Assembling and Installation Method** 

## Installation Method 

- ¡ Screw mounting requires considering the product weight for safety fixtures. 

- ¡ To keep enough insulation distance between screws and internal components, length of the mounting screw should not exceed recommendation as shown in right figure.

- ¡ When mounting the power supply with screws, it is recommended that this be done as shown below. 

If other methods are used, be sure the weight of the power supply is taken into account. 

The following figures show examples for the HFA3500TF-48 and -65. The HFA3500TF-90, -130, -200, and -300 models have different output interfaces. Please refer to the external views for the HFA3500TF-90, -130, -200, and -300.

- ¡ The power supplies have a built-in forced cooling fan. Do not block ventilation at the suction side and its opposite side. 

- ¡ If you use a power supply in a dusty environment, it can cause a failure. Please consider taking such countermeasures as installing an air filter near the suction area of the system to prevent a failure.
