In accordance with the wiring rules, AS/NZS 3000:2007 and IEC 61000-3-11, the CFEWH is intended for use
in premises having a service current capacity
≥
100 A per phase, supplied from a distribution network having
a nominal voltage of 400/230 VAC. The Live-Neutral electrical supply connections Live, Neutral and Ground
(Earth
) must be
permanently connected to the Terminal Block (14) mounted on the PCBA V6.2 as shown
– noting the correct polarity
Live – L and Neutral – N.
Bring the Live, Neutral supply through the Electric Mains Supply Cable Gland (15) as shown.
The LIVE wire
must be connected to the terminal L
The NEUTRAL wire

Bare Element Water Heater. The appliance
must be correctly
connected to the mains earth.
In order to prevent a hazardous circumstance occurring due to the inadvertent resetting of the
thermal cut out, the electrical supply to this appliance
must not be supplied through an external
switching device, such as a timer – nor can it be connected to a circuit that is regularly switched
on and off by the electricity supply utility.
IMPORTANT
Live-Neutral/Ground (LNG) connection is polarity dependent.
Incorrect wiring connection will cause FC – Earth Leakage Detection Error.
