5.4 Inputs
All voltage measurement inputs must originate at circuit breakers or fuses rated 5 Amps or
less. 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 in accordance with IEC 60947-2 or IEC 60947-3.
When using
voltage transformers
you have to ensure that their secondary connections
never will be short-circuited.
No fuse may be connected upstream of the
current measurement inputs
!
When using
current transformers
their secondary connectors must be short-circuited
during installation and before removing the device. Never open the secondary circuit under
load.
The connection of the inputs depends on the configured system (connection type).
