Electric requirements
Power requirements
Check the markings on the rating plate of the water heater to be
certain the available power supply corresponds to the water
heater requirements.
This water heater must be directly connected to a 230V-240V
AC, 50Hz mains power supply. When connected off grid,
please make sure a 230V-240V AC 50Hz true sine wave power
supply is available.
Do not connect this unit to inverters providing square sine
waves.
Electrical connections
The water heater must be installed on its own circuit with a
breaker switch installed directly at the switchboard.
▶ Remove the top cover.
▶ Route the power supply cord through the orifice next to the
drain port.
▶ Open the electric connection box.
▶ Connect the power supply wires and earth tab directly to
the provided terminal block, ensuring there are no
unnecessary excess wire loops inside the electric
connection box.
▶ Close connection box and place in dedicated slot in the
module base.
▶ Close the electric connection box.

Electrical test requirements
AS/NZS 3000:2000, clause "Results" (6.3.3.3.2) states:
"The value of 1 MOhm may be reduced to 0.01 MO for sheathed
heating elements"
This water heater has been tested to AS/NZS 3350.1:2002
clause 16 "Leakage current and electric strength" and passed
the requirements of this Standard. Therefore, this water heater
CAUTION:
Do not incorrectly connect electrical
connections. 230-240V AC must be applied
to L and N wires as shown in Fig. 11. Failure
to do so will VOID the warranty and can result
in irreversible damage to the appliance.
WARNING:
All electrical work and fixed wiring must be
carried out by a qualified professional and in
accordance with the Wiring Rules AS/NZS
3000 and local authority requirements.
Required 15A installation to be available in
place.
WARNING:
Proper ground connection is essential.
The presence of water in the piping and
water heater does not provide sufficient
conduction for a ground. Non metallic
piping, dielectric unions, flexible
connectors, etc., can cause the water heater
to be electrically isolated.
WARNING:
This water heater contains electronic
equipment and 500V insulation tests must
only be conducted between active and earth
and between neutral and earth. An active to
neutral test WILL damage the electronics.
