8.1 Electrical connection for Electric AES (Booster)
For safe performance this water heater is fitted with a thermostat and an over
temperature cut-out. These devices should not be tampered with or removed.
Do not operate this water heater without the electrical thermostat and over
temperature cut-out in the circuit.
The electric element is only connected in models using an electric AES system. No
connection is made to the electric element for gas AES systems.
The electrical booster requires a 220
– 250 volt single phase AC power supply with a
capacity suitable for the kilowatt rating of the element selected for the application. For
example, a 2.4 kW element requires a 10 amp supply capacity, a 3.6 kW element
requires 15 amp supply capacity.
Electrical entry for the electric AES is achieved via a 20mm opening adjacent the element
surround.
A cable gland with orange circular cable, or 19mm conduit with 3 core TPS cable must be
used to make electrical supply to the unit.
The power supply must be protected by an individual fuse or circuit breaker rated
to suit the booster size.
The supply to the solar water heater can be operated directly from the switchboard or via
a remotely mounted switch or time clock as requested by the customer. The correct
alternative should be established with the Conergy dealer prior to installation.
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:
3. Earth - connected to the earthing stud marked with the earth symbol;
4. Active - connected to the terminal block position marked A or Active;
5. 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.
There is a risk of damage to the system if the installation sequence is not followed.
