IMPORTANT
This unit must be installed within a fire-resistant casing which must be
made of a plastic material with a 94-5VB rating or higher so as to comply
with Regulation EN-60950.
Power must be supplied to the primary of the “TF-104” transformer via a
thermo-magnetic circuit breaker. This not only protects the whole system,
but also serves as its on/off switch.
Do not tamper with this system, in case of anomalies or enquiries please
contact our technical support service.
