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.
