Low voltage current transformers, multict KBR
4. Installation
Ensure a safe working environment during fi tting, maintenance and installation work.
Interrupt the power supply of the primary conductor and secure it against unintention-
al restarting.
Open the current transformer and fasten it to the primary conductor with the help of
the fi xing clips supplied in the delivery. P1 points to the power source, P2 to the load.
The arrow on the rating plate indicates the direction of energy fl ow.
Caution:
Do not close the current transformer yet, as high voltages can occur at the
secondary terminals!
Caution:
Ensure the cut surfaces of the split core are clean. Avoid hand contact (sweat)!
Connect the secondary cables in the current transformer to the measuring device (am-
meter or meter etc.). Observe the operating instructions for the measuring device.
Check whether the current transformer is fi tted properly and the secondary wires are
connected properly.
Close the current transformer – press together until the lock engages.
I f necessary, switch on the power supply of the primary conductor again.
