Make sure that the working environment is safe during assembly, maintenance and installation work. 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 (copper bar or round conductor) through the window aperture of the current transformer housing. The window aperture is marked with "P1 (K)".
The device is mounted on a mounting plate. Use the fastening materials included in the scope of delivery for this.
Mounting on a mounting plate takes place with the base brackets also included in the accessories pack.
The current transformers can also be fastened to 35 mm DIN rails by means of a snap-on mounting (ZB8201-04x0), which is available as an accessory.
Make the secondary connections. Observe the markings "k (S1)" and "l (S2)" of the secondary terminals.
