Note: 1. If the potentiometer is to be operated often, use a 2W1kΩ potentiometer.
2. 0.1K and 0.2K do not contain a transistor.
3. Terminals SD and SE are isolated.
4. Terminals SD and 5 are common terminals. Do not earth them to the
ground. Terminals SD and 5 are not isolated. (Those of the 400V class are
isolated.)
5. When terminals PC-SD are used as a 24VDC power supply, be careful not
to short these terminals. If they are shorted, the inverter will be damaged.
