Product Usage Instructions
Installation:
The Rogowski coil must be installed in an environment that meets the
maximum operating conditions specified for the coil.
Connection and Installation:
- The connection and installation of the Rogowski coil should only be done by qualified technicians who are aware of the risks associated with voltage and current presence.
- Before any operation, ensure that bare conductor wires are not powered and that there are no neighboring bare conductors under power.
INTRODUCTION
The manual is intended only for qualified, professional, and skilled technicians, authorized to act by the safety standards provided for the electrical installations. This person must have appropriate training and wear suitable Personal Protective Equipment.
WARNING! It is strictly forbidden for anyone who does not have the above- mentioned requirements to install or use the coil.
It is forbidden to use the coil for purposes other than intended ones, specified in this manual. The symbols on the product are following described:
- Attention! Refer to the user manual.
- Protected throughout by DOUBLE INSULATION or REINFORCED INSULATION.
- Do not apply around or remove from HAZARDOUS LIVE conductors without additional protective means.
- Complies with the relevant European standards.
- Underwriters’ Laboratory Inc. recognized component.

SAFETY INSTRUCTIONS
The Rogowski coil must be installed in an environment that is according to the maximum operation conditions of the coil itself.
WARNING! The connection and installation of the Rogowski coil must be
carried out only by qualified technicians aware of the risks involved in the
presence of voltage and current.
Before carrying out an operation, check if:
- bare conductor wires are not powered, 2. there are no neighbor bare conductors not powered
NOTE : The Rogowski coil complies with UL 61010-1 and UL 61010-2-032 standards and following amendments. The installation must be carried out according to the standards in force, the instructions of this user manual, and the coil insulation value to avoid any danger to people.
The Rogowski coil is a sensor for accurate measurement so it must be handled with care. Before use, read the following instructions carefully.
- Do not use the product if damaged.
- Always wear protective clothing and gloves when required.
- Avoid strongly twisting, blowing, and pulling load on the product: the measurement accuracy may be impaired.
- Do not paint the product.
- Do not put metallic labels or other objects on the product: the insulation may be impaired.
- It is forbidden to useproductst different from the manufacturer’s specifications.
MOUNTING
WARNING! Before installing the coil around a conductor not insulated,
check that it is not powered otherwise switch the circuit OFF.
WARNING! Check if the coil is properly installed: a bad locking can
affect measurement accuracy and the coil will become sensitive to adjacent
conductors or other sources of electromagnetic fields.
NOTE: The coil must not fit tightly around the conductor, therefore its internal diameter must exceed that of the conductor.
To carry out the installation, proceed as follows:
- Fit the coil around the conductor, bringing the coil ends together.
- Lock the coil by turning the ring as indicated in picture A.
CONNECTIONS
The coil has an arrow indicating the load side.
In the case of the model WITHOUT integrator refer to picture B:
- A = SOURCE
- B = LOAD
- WHITE wire, OUT+
- BLUE wire, OUT-
- SHIELD, connect to GND or OUT-If the cable is provided with crimp pins:
- YELLOW crimp pin, OUT+
- WHITE crimp pin, OUT-
In the case of model WITH integrator refer to picture C:
- A = SOURCE
- B = LOAD
- WHITE wire, OUT+
- BLACK wire, OUT-
- RED wire, positive power, 4…26 VDC
- BLUE wire, negative power, GND
- SHIELD, connect to GND
The coil is protected against the reverse polarity of the power supply.
MAINTENANCE
