INTRODUCTION
The manual is intended only for qualified, professional and skilled
technicians, authorised to act in accordance with 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 requires 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 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, 2. there are no neighbor bare conductors not powered
NOTE: The Rogowski coil complies with UL 61010-1 and UL 610102-032
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.
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.
Refer to picture B:
A = SOURCE
B = LOAD

- 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-
MAINTENANCE
