Connection modes
All voltage measurement inputs must originate
at circuit breakers or fuses rated 10 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 se-
condary 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 confi gured
system (connection type). The required device external
fusing of the voltage inputs is not shown in the following
connection diagrams.
