Danger

 

Dangerous voltage on current transformers 

Dangerous 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. The high voltage produced will destroy the

transformers. 
The current transformer secondary circuit must be short-circuited before 

de-installing the meter. Installation and de-installation of the meter must 

only be performed by qualified meter installers, with strict adherence to the

utility's safety regulations. 

 
1.  Short-circuit the current transformers using the provided assembly. 

2.  Switch off the voltage. The phase voltage display (L1 L2 L3) 

disappears. 

3.  Switch off tariff inputs and synchronisation input. Check if the 

corresponding indicators disappear from the display. 

4.  Switch off the voltage for the additional power supply. 

5.  Carefully withdraw the meter from the rack.
