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.

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 parameters of the system.
• Switch the system off before commencing with the installation!

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 functional safety of the current transformer.
• "Open operation", i.e. operation of the current transformer without secondary wiring, must be avoided at all costs.
