Product Usage Instructions
Introduction
The Rogowski coil is designed for use by qualified technicians in accordance
with safety standards for electrical installations. Only individuals with
appropriate training and Personal Protective Equipment should handle the coil.
Safety Instructions
Install the Rogowski coil in an environment that meets its operational
conditions. Connection and installation should only be done by qualified
technicians. Ensure bare conductor wires are not powered and there are no
neighboring powered conductors before installation.
Mounting
Proper installation is crucial for accurate measurements. Ensure the coil is
not tightly fit around the conductor to prevent interference from adjacent
sources. To install, fit the coil around the conductor and lock it by turning
the ring as shown in picture A.
Connections
For models with an integrator, follow the connection diagram provided. The
coil is polarity protected. Connect the wires as follows:
- WHITE wire – OUT+
- BLACK wire – OUT-
- RED wire – Positive power (4-26 VDC)
- BLUE wire – Negative power (GND)
- SHIELD – Connect to GND

SAFETY INSTRUCTIONS
The Rogowski coil must be installed in an environment which are according to the max 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 to the presence of voltage and current. Before carrying out an operation, check if:
- bare conductor wires are not powered,
- there are no neighbour 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 in accordance with the standards in force, the instructions of this user manual and the coil insulation value in order to avoid any danger for 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 to strongly twist, blow and to perform 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 any use of the product different from the manufacturer specifications.
MOUNTING
WARNING! Before installing the coil round 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: Coil must not fit tightly round the conductor, therefore its internal diameter must exceed that of the conductor. internal diameter must exceed that of the conductor. To carry out the installation, proceed as follow:
- Fit the coil round 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 case of model WITHOUT integrator refer to picture B:
A = SOURCE
B = LOAD
-
WHITE wire, OUT+
-
BLUE wire, OUT3. SHIELD, connect to GND or OUT
If the cable is provided with crimp pins:- YELLOW crimp pin, OUT+
- WHITE crimp pin, OUT
In case of model WITH integrator refer to picture C:
A = SOURCE
B = LOAD
- WHITE wire, OUT+
