Power Requirements; Dedicated Rcd Safety Circuit - Elecro Engineering Cygnet Evolution 2 Installation & Operating Manual

Connections
•
To connect the power supply cable, remove access cover (see Fig. 8).
•
Make sure that all connections to the terminal block are correct as per the label inside the heater
and they are tight.
•
Make sure not to expose the cable to anything which can cause damage to it i.e. sharp edges, hot
surfaces, or crush hazards.
•
The cable should be fixed to avoid any trip hazard.

2.6 Dedicated RCD Safety Circuit

•
The heater is fitted with a high limit Safety Circuit which must be connected to a dedicated RCD
and circuit breaker.
•
The Safety Circuit is constantly monitoring the flow tube temperature. Air pockets, incrustation,
debris build-up or faulty components can be a reason of a sudden temperature rise inside the flow
tube. To protect heating elements and other components the Safety Circuit will trigger the RCD
and shut down the power to the heater.
WARNING: The Safety Circuit must be connected. Failure to do so will void the warranty and
might result in product failure.
NOTE: The Safety Circuit is fitted with a TEST BUTTON which must be tested after
completing installation of the heater to confirm it is operating correctly. When
pressed, the RCD should instantly trip and cut the power to the unit (See Fig. 9).
