All voltage measurement inputs must originate at circuit breakers or fuses rated by 1 Amps. This
does not apply to the neutral connector. You have to provide a method for manually removing
power from the device, such as a clearly labeled circuit breaker or a fused disconnect switch.
When using
voltage transformers
you have to ensure that their secondary connections never will be
short-circuited.
The connection of the inputs depends on the confi gured system (connection type).
5.4 Power supply
A marked and easily accessible current limiting switch has to be arranged in the vicinity of the
device for turning off the power supply. Fusing should be 10 Amps or less and must be rated for
the available voltage and fault current.
