mains power with a contact opening of at least 3 mm on each pole.
The external construction like the fuses, main switch, fault current circuit breaker,
have to be arranged by the owner/operator according to be local regulations. Fuse,
earth leakage circuit breaker and main switch are to be installed as per local
regulations.
CONNECTION REQUIREMENTS
The electrical installation must be equipped with a freely accessible all-pole disconnecting
device in accordance with the overvoltage category III. (Master switch with clearly marked
on/off settings e.g. “O” and “I” or additional indicator light). This means that for full separation
each pole must have a contact gap according to the conditions of the overvoltage category
III. The device shall be capable of being locked in the off-position and shall comply with IEC
60447. A supply main switch must not be incorporated in the power supply cord. A Class-A
ground fault circuit interrupter (GFCI) has to be used for Canada. Should the operation of the
tanning device 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.
