Safety note
These transformers may only be used in electrical or power electronic applications which fulfill the relevant regulations
(standards, EMC requirements,…).
Caution, risk of electric shock
- Pay attention to protect non-insulated high-power current carrying parts against direct contact (e.g. with a protective
enclosure).
- When installing this sensor please make sure that the safe separation (between primary circuit and secondary
circuit) is maintained over the whole circuits and their connections.
- The sensor may only be connected to a power supply respecting the SELV/PELV protective regulations according
to EN 50 178. The installation of the power supply must be short-circuit-proof.
- Disconnecting the main power must be possible.
- The current sensors support a safe separation. The creepage and clearance distances are taken as a basis for the
rated voltage. They are the shortest distance between the secondary connection and the sensor's window. The actual
clearance and creepage distances depend on the position of the primary conductor respectively on the actual shortest
distance between the primary conductor and the secondary connection.
