WARNING!
In the case of a fixed connection, the storage heater must have a isolating device that works across all channels
(phase, neutral, earth), with at least 3 mm contact distance, installed between it and the mains power supply. This
requirement can be fulfilled by automatic circuit breakers.
Fig. 22: Connect the electrical cables to the terminal strips.
Example connection with heater circuit-breaker, room temperature controller and a standard charge control system.
