• The domestic socket must also provide a protective conductor. Make sure that the connection of the
protective conductor of the domestic installations to the chamber’s protective conductor meets the
latest technology. The protective conductors of the socket and plug must be compatible!
• Prior to connection and start-up, check the power supply voltage. Compare the values to the specified
data located on the chamber’s type plate (left chamber side, bottom right-hand, see chap. 1.4). We
recommend the use of a residual current circuit breaker.
• When connecting, please observe the regulations specified by the local electricity supply company as
well as the VDE directives (for Germany).
• Pollution degree (acc. to IEC 61010-1): 2
• Over-voltage category (acc. to IEC 61010-1): II
CAUTION
Danger of incorrect power supply voltage.
Damage to the equipment.
Check the power supply voltage before connection and start-up.
Compare the power supply voltage with the data indicated on the type plate.
See also electrical data (chap. 25.4).
To completely separate the chamber from the power supply, you must disconnect the power
plug. Install the chamber in a way that the power plug is easily accessible and can be easily
pulled in case of danger.
