General Notes

1. In order to reduce the external interference, twisted pair or shielding wire is recommended as the control line of RS485.

2. SSR should adopt random-on type, zero-crossing SSR cannot be used.

3. DRF12S220P-S4F power supply is three-phase with N, and each circuit voltage is 220 VAC. DRF12S380TP-S4F power supply is three-phase without N.

4. In order to improve the accuracy of temperature measurement, it is suggested to choose a shielded thermocouple.
