Notes:
① During installation, the electric heater should be supplied with three-phase power separately.
When only one group of the electric heater is installed, please follow the wiring of any group of the
diagram shown above.
② Quantity of the AC contactors should match with that of the electric heater installed. Proper AC
contactors which meet the actual demands should be adopted.
③ The wiring mode depends on if the tank-type electric heater is equipped with a thermostat or
not.
④ Proper power lines should be used and those that do not meet actual demands should be
avoided.
⑤ Never open the electric box for wiring of the mainboard by the user themselves.
