(8) Cover the system for safety
To use this product safely, be sure to cover the inverter board and the noise filter with an enclosure made of
metal or flame-retardant material with sufficient strength to prevent direct touch as shown in Fig. 3-10. The
enclosure should have slits for heat radiation and holes for cables to pass through.
In addition, regarding the disconnecting device (circuit protector), it should be properly located as follows.
- Do not locate it so that it is difficult to operate the device.
- It must be suitably located and easily reached.
- It must be marked as the disconnecting device for this product.
Provide sufficient ventilation
to prevent heat from building
up inside the case.

3.2 Power supply

There are two ways to supply main power to the inverter board.
When AC voltage is input as main power, sub power (DC15V) is generated internally. System configuration
is shown in Fig. 3-11.
When DC voltage is input as main power, sub power (DC15V) must be supplied externally. System
configuration is shown in Fig. 3-12.
USB5V power supply for communication I/F is needed for both cases.
When using the DC input, be sure to input a 15 V sub power supply before inputting the main power supply.
Also, when shutting off the power supply, be sure to turn off the 15V sub power supply after turning off the
main power supply. Inputting main DC power without a 15V sub power input may damage the board.
The inrush current limitation function does not work with this product when DC power is supplied. Therefore,
when using DC power supply, the current limit of about 10 to 30A should be applied on the power supply side,
or the power supply voltage should be turned on slowly over about 50 to 100ms.
Similarly, when DC voltage is turned off, it is recommended to disconnect the output or slowly lower the power
supply voltage to prevent large current from flowing into the power supply side.
