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 through the opening of the current transformer housing
The device can be fastened directly to the primary conductor or alternatively to a mounting plate. Use the fastening materials included in the scope of delivery for this.

Fastening the base plate with screws in the four holes
Free suspension on the cable with the help of cable ties through the hooks on the back for attachment
All current-carrying conductors/lines must be routed together through the measuring current transformer, see Fig, "Use in single-phase and 3- and 4-pin three-phase systems".
Bending of the primary conductors may only take place from the specified minimum distance. The bending radii specified by the manufacturers must be observed.
