Mounting instructions for snap ferrite ring
Install the snap ferrite ring around the wires for current/voltage measurement

2. Remove the key from the keyholes by carefully pulling it out with one
hand while holding the snap ferrite ring with the other hand.
3. Place the snap ferrite ring around the wires for current/voltage
measurement and lock the ring by closing it. The snap ferrite ring
should be installed as close to the terminal block as possible. Fig. 5.1.-2
shows the preferred position of the snap ferrite ring after installation.
If the protection relay is installed in a place where it is subject to
vibration, such as on marine applications, the snap ferrite ring
needs to be attached to a stationary part of the switch gear
cubicle. This can easily be done by fastening the snap ferrite ring
to the cubicle wall with a screw.
