The unit has to be connected to the 400 V mains; the connection
is to be protected by fuses. For details on the fuses, please
refer to the section „Technical data“. An FI protective switch is
required in any case. KBL Solarien AG recommend the following
type: KBL 3200 0770 00.
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).
