2.2 Installation
The following steps outline the installation process:
1. Connect a Rogowski coil CT (model RCTxx-1000 in any length) to the integrator
2. Wire the 1A output to the protection relay or power meter which will take the signal
The diagram below illustrates how to connect the integrator.

Input
The Rogowski coil provides the input to the integrator. Connect the Rogowski coil to the input channel on the integrator. Be sure to observe
the correct wire polarity: the white lead is positive (+) and the brown lead is negative (-).
•
Connect the white lead to 'IN+' and the brown lead to 'IN-'. The Shield of the Rogowski coil should be left floating.
•
Open the coil by pulling apart the black connector of the CT.
•
Install the CT around the conductor to be measured. Verify the CT is installed with the CT facing the same direction as the current flow
direction as indicated by the arrow on the black connector.
•
Connect the coil back together.
Output
Connect the output channel to the protection relay or the 1A current input on the power meter.
•
The 'OUT+' is to be connected to the positive current terminal of the relay/meter.
•
The 'OUT-' is to be connected to the negative current terminal of the relay/meter.
Power Supply
The RIK requires 24Vdc power to operate. The power supply requires a 100-240Vac (50/60Hz) input and outputs 24Vdc to power the
Integrator.
•
Connect the input power supply that is between 100-240Vac to the 'L' and 'N' terminals of the power supply.
•
Connect the V+ and V- of the power supply to the +24Vdc and GND terminals of the Integrator.
