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

Interrupt the power supply of the primary conductor and secure against being switched on again inadvertently.
Install the current transformer on the primary conductor.
To do this, feed the primary conductor (round conductor) through the window aperture of the current transformer housing. The window aperture is marked with "P1" and "P2".
Make the secondary connections.
Observe the markings "S1" and "S2" of the secondary terminals

Notice

Observe the conductor cross-sections and lengths!

The conductor cross-sections and lengths specified below must be adhered to for trouble-free function!

Measuring circuit

To fasten the device to a mounting plate, use the optionally available snap-on mounting (ZB8201-0110) for DIN rails.
This can be fastened to the mounting plate with two screws, max. Ø 5 mm.
Fastening to a 35 mm DIN rail also takes place with the help of the optionally available snap-on mounting ZB8201-0110
Check whether the current transformer is mounted correctly and the secondary conductors are connected correctly.
Switch on the power supply to the primary conductor again.
