4 to 20mADC(+)
Note: 1. If the potentiometer is to be operated often, use a 2W1k potentiometer.
2. Terminals 5, SD and SE are isolated.
3. Terminals SD and 5 are common terminals. Do not earth them to the
ground.
4. 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.
