6. Connections & Initial operation
6.1 Connecting the mains
voltage
DANGER
Live parts
Risk of fatal injury due to electric shock
when 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 qualifi ed expert staff.
The connection to the 400 V mains must be protected
by fuses. Their specifi cations are listed in the chapter
“Technical data”.
CONNECTION REQUIREMENTS
The electrical installation must be equipped with a
freely accessible all-pole disconnecting device in
accordance with the overvoltage category III. This
means that for full separation each pole must have a
contact gap according to the conditions of the over-
voltage category III.
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.
6.2 Connecting an external
audio source
When connecting an external audio source (studio
music), pay attention to the correct polarity.
