5.5 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.
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).
When
measuring in systems with neutral wire
the connection of the inputs for the
neutral current measurement and the earth connector for determining the zero
displacement voltage is optional.
