Outline and Installation Dimensions

WARNING!

● Rogowski coils must only be installed and operated by qualified personnelwho have received relevant electrical training and hold appropriatecertifications.

● During installation or operation, users must comply with applicable nationalsafety regulations and the manufacturer’ s operating instructions. Thedevice shall only be used in electrical or electronic equipment that meetsspecified parameter standards and safety requirements.

NOTE!

● Safe and trouble-free operation of the coil can only be guaranteed underconditions of proper transportation, storage, installation, careful handling,and regular maintenance.

● Avoid excessive bending, piercing, over-compression, or sharp kinking -such actions will significantly reduce the device’ s accuracy and service life.

ELECTRICSHOCKHAZARD!

● When handling the Rogowski coil, certain parts of the module may carry hazardous voltage. Users must take all necessary precautions to prevent electric shock.

● The Rogowski coil is an internal component containing live conductive parts that must not be touched after installation.

● A protective cover or additional insulation barrier must be installed around the Rogowski coil’ s mounting area.

● If maintenance is required due to equipment failure, ensure there are no hazardous live components within or near the power system before proceeding – otherwise, disconnect the main power supply before performing any repair or servicing operations.

Note: integrators are available, special specifications and sizes can be customized.

Do not forcibly pullor stretch!

Do not forcibly bend!

Do not tie with cableties while bent!
