5.1 Connection instructions
!WARNING
Danger! Electric voltage!
►The entire connection of the device must take place while the device is de-energized.
!CAUTION
Pay attention to additional information provided
►Before commissioning the device, make sure that the supply voltage matches the voltage
specifications on the nameplate.
►Provide a suitable switch or power-circuit breaker in the building installation. This switch
must be provided close to the device (within easy reach) and marked as a circuit breaker.
►An overload protection element (rated current £ 10 A) is required for the power cable.
If replacing an older Soliswitch FTE3x with a new FTE20-type device, note that the free
ends of the cable to the terminal are longer than in the older version (approx.
5 to 6 cm (1.97 to 2.36 in)).
