High voltage on transformer
High voltage is produced by the current transformers when the secondary
circuit is broken while current is flowing in the primary.
Contact with the transformers when under voltage will result in severe
personal injury or death. In addition, the high voltage produced will
destroy the transformers.
The current transformer secondary circuit must be short-circuited before
de-installing the meter. Connecting and disconnecting the meter must only
be performed by qualified meter installers, with strict adherence to the
utility's safety regulations.
Power on
Incorrect connections could damage the meter or result in the meter
measuring incorrectly.
We recommend all connections be checked before applying power.
1. Open-circuit the current transformer secondary circuit using the
provided assembly.
2. Plug the f9 into the pre-wired rack
3. Switch on the voltage and current.
The power must be connected and all 3 phases under load. If the phases
are only connected to voltage, the optical test outputs are continuously lit.
