The unit has to be connected to the 400 V mains; fuses protect
the connection. For details on the fuses, please refer to the sec-
tion „Technical data“. An FI protective switch (residual current-
operated circuit breaker) is required in any case. KBL recom-
mend the following type: KBL 3200 077000.
Should any interference occur due to the operation of your tan-
ning unit with the mains, e.g. with ripple-control systems (TRA),
consult your power-supply company regarding the installation of
corresponding blocking elements (audio frequency suppressor).
