a remotely mounted switch or time clock as requested by the customer.
A means for disconnection (e.g. isolator) must be included in the fixed wiring to the solar
water heater in accordance with the wiring rules.
Final electrical connection at the solar water heater is as follows:
1. Earth - connected to the earthing stud marked with the earth symbol;
2. Active - connected to the terminal block position marked A or Active;
3. Neutral - connected to the terminal block position marked N or Neutral.
Do not turn on the power supply until the solar water heater has been filled with
water and pressurised.
