touching live parts.
•
Disconnect from mains and secure
against reconnection!
Both the power supply and the related connection
work must comply with national standards, e.g. those
set up by VDE in Germany. The connection work
must only be performed by qualified expert staff.
The connection to the 400 V mains must be protected
by fuses. Their specifications are listed in the chapter
“Technical data”.
A residual current-operated circuit breaker (RCD)
with short time delay is absolutely required. KBL AG
recommends the following type: KBL 3200 0770 00
(type (Typ ABB F 204 A - 40//0,03 AP-R).
Should the operation of the tanning unit cause any
interference in the power supply network, e.g. with
ripple-control systems (TRA), consult your power
supply company to have corresponding blocking
elements (audio frequency suppressors) installed.

Level adjustment studio signal
The voice / audio system components are built in
the middle of the bench part (vacuum housing) of
the sunbed. The potentiometer which serves of
the external audio signal is located on the left side
of the housing. To avoid overdrive, select the level
adjustment accordingly. The level setting depends
on the strength of the external signal and should be
carried out by a service engineer. Adjustment of the
sound level can only be conducted in the service
menu.
