3�2�- INSTALLATION
The device will be installed on a panel (92
+0.8
x 92
+0.8
mm panel drill hole, in compliance with DIN
43700). All connections are located inside the electric panel.
Terminals, opening covers or removing elements can expose parts that are hazardous
to the touch while the device is powered. Do not use the device until it is fully installed.
The device must be connected to a power circuit that is protected with gl (IEC 269) or M type fuses with
a rating of 0.5 to 2 A. It must be fitted with a circuit breaker or equivalent device, in order to be able to
disconnect the device from the power supply network.
The power and voltage measuring circuit must be connected with cables that have a minimum
cross-section of 1mm
2
.
The secondary line of the current transformer will have a minimum cross-section of 2.5 mm
2
.
The temperature rating of insulation of wires connected to the device will be at minimum 62ºC.
3�3�- CVM-C10-FLEX: ROGOWSKI SENSORS
The
CVM-C10-FLEX
model measures currents using flexible sensors, based on the Rogowski coil prin-
ciple.
The flexibility of the sensor allows it to measure an alternating current irrespective of the position of
the conductor.
CIRCUTOR
has a Rogowski sensor model that can be used with the
CVM-C10-FLEX
:
FLEX-MAG
.
Table 3 shows the connection of the sensors and
