NOTE
• To cut the power in case of an emergency by unplugging, the instrument or any other item must
not block the mains plug! In this case, the plug must be able to be pulled out instantly.
• When the system is installed with a locked or secured plug an external power switch is required.
• When the system is installed stationary (without power plug) an external power switch is
required.
• External power switches (e.g. emergency stop switches) must meet IEC 60947-1 and IEC
60947-3 requirements. Such devices must be clearly labeled and accessible at any time.
• Additional electrical safety measures such as residual current breakers may be necessary to meet
local laws and regulations!
• External connections and extension lines must be provided with a grounded conductor lead
(3-pole couplings, cord or plug equipment). All used power cords must meet the input power
requirements.
