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:

1. bare conductor wires are not powered,
2. there are no neighbour bare powered conductors

NOTE : The Rogowski coil complies with IEC 61010-1 and IEC 61010-2-032, UL 2808 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, make sure to comply with the following statements:

• Always open or disconnect circuit from power-distribution system (or service) of building before installing of servicing coils.
• The coils may not be installed in equipment where they exceed 75 percent of the wiring space of any cross-sectional area within the equipment.
• Restrict installation of coil in an area where it would block ventilation openings.
• Restrict installation of coil in area of breaker arc venting.
• “Not suitable for Class 2 wiring methods” and “Not intended for connection to Class 2 equipment”.

⚠ 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:

1. Fit the coil round the conductor, bringing the coil ends together.
2. Lock the coil by turning the ring as indicated in picture A.

CONNECTIONS

The coil has an arrow indicating the load side.
