Installation SCT4616/SCT4716/SCT4816

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.

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.
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.
Open the current transformer and fasten it to the primary conductor with the help of the fixing clasps included in the scope of delivery.
P1 points to the power source, P2 to the loads.
The arrow on the name plate indicates the direction of energy flow.
Caution: Do not close the current transformer yet, high voltages may occur at the secondary connections!
Caution: Ensure that the cut surfaces of the split core are clean. Avoid hand contact (sweat)!
Connect the secondary conductors of the current transformer to the measuring device (ammeter, meter, etc.). Observe the operating instructions for the measuring device when doing this.
Check whether the current transformer is mounted correctly and the secondary conductors are connected correctly.
Close the current transformer – press together until the closure engages.
If necessary, switch on the power supply to the primary conductor again.
