labelled fuse that is positioned close
by and a circuit breaker (alternatively:
a line safety switch).

•

are dangerous to touch.

•

Voltages that exceed the permissible
network rated voltages must be
connected via a voltage transformer.

•

Measured voltages and currents must
derive from the same network.



NOTE!
As an alternative to the fuse and circuit
breaker, you can use a line safety switch.

The voltage measurement inputs are designed
for measurements in low voltage networks, in
which rated voltages of up to

• 277 V phase to earth and 480 V phase to

phase in the 4-conductor system or

• 480 V phase to phase in the 3-conductor

Voltage measurement

The device only determines measured values
if measured voltage of >10 Veff is present on
at least one voltage measurement input.

CAUTION!

Risk of injuries or
damage to the device

Failure to observe the connection conditions
for the voltage measurement inputs can cause
injuries to you or damage to the device.
Therefore, note the following:

•

The voltage measurement inputs

•

must not be occupied with DC voltage.

•

must be provided with a suitable,
labelled fuse that is positioned close
by and a circuit breaker (alternatively:
a line safety switch).

•

are dangerous to touch.

•

Voltages that exceed the permissible
network rated voltages must be
connected via a voltage transformer.

•

Measured voltages and currents must
derive from the same network.



NOTE!
As an alternative to the fuse and circuit
breaker, you can use a line safety switch.

The voltage measurement inputs are designed
for measurements in low voltage networks, in
which rated voltages of up to

• 277 V phase to earth and 480 V phase to

phase in the 4-conductor system or

• 480 V phase to phase in the 3-conductor

system occur.
