DANGER
Open transformer circuits lead to electric shock and arc flashover!
Disregarding this will result in death, physical injury or considerable damage to property!
• Never open the secondary circuit of the current transformer under load.
• Short-circuit the secondary current terminals of the current transformer before removing the device.
WARNING
Hazardous voltage can lead to electric shock and burns!
• Make sure that the details on the name plate and in the "Technical data" correspond to the operating pa-
rameters of the system.
• Switch the system off before commencing with the installation!
WARNING
Induction of high voltages into the secondary circuit!
• If the secondary circuit of the current transformer is not under load (open), high voltages are induced on
its secondary terminals. The voltage values occurring there represent a danger to persons and the func-
tional safety of the current transformer.
• "Open operation", i.e. operation of the current transformer without secondary wiring, must be avoided at
all costs.
