• 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 lat-
est 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).
• When connecting, please observe the regulations specified by the local electricity supply company and
as well as the VDE directives (for Germany). We recommend the use of a residual current circuit
breaker.
• Pollution degree (acc. to IEC 61010-1): 2
• Installation 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.
Remark when operating the chamber with a power frequency of 60 Hz:
WARNING
High leakage current.
Electrical hazard.
Earth connection essential before connecting supply. Check socket before inserting
plug.
