RECmax-CVM
Instruction Manual
3�2�- INSTALLATION
While the device is connected, the terminals, opening the cover or removing elements
can expose parts that are hazardous to the touch� The device must not be used until
the installation process is complete�
The
RECmax-CVM
must be installed inside an electric panel or enclosure and mounted on a DIN rail
46277 (EN 50022)�
The device has connection indicator LEDs, indicating the presence of voltage� Even if these LEDs are
not on, the user must still verify that the device is disconnected from all power supplies�
3�2�1�- MEASUREMENT OF THE EARTH LEAKAGE CURRENT I
Δ
The earth leakage current must be measured using the
WGC
earth leakage transformer included with
the device�
The
WGC
transformer, supplied
with a cable and 2-pole connector
,
must be connected to terminals 1
and 2 of the device (see
)
It is recommended to place the earth leakage transformer at the bottom of the circuit breaker (
)�
The external earth leakage transformer is necessary for the device to operate cor-
rectly� Even if its installation only appears linked to the correct working of the earth
leakage protection, failing to install it will affect other functions of the device, such
as the reclosing and display of parameters on the
RECmax-CVM
display�
An incorrect or faulty connection of the earth leakage transformer means loss of
the earth leakage protection and possible risk of electric shock�
In case of a faulty connection of the earth leakage transformer or if this transformer is not compati-
ble with the
RECmax-CVM,
the screen shown in
will appear�
