INSTALLATION
Installation must only be carried out by qualified personnel.
Before installation, disconnect from the power supply.
Connect the device as shown on the diagram below
(N.B. some optional functions do not need to be cabled).
When installing the device, make the connections
between the relay and the differential toroid as short as
possible.
Do not put relay cables or the differential toroid beside
power conductors.
Do not place differential toroids close to sources of
intense magnetic fields.
>Note
This differential relay conforms to type A which trips
sinusoidal alternating currents and pulsed currents,
whether they are applied suddenly or change slowly.
This product is also immune to interference.
This relay must be installed in accordance with the
regulations currently in force.
The device must be checked periodically to see that it
complies with the regulations.

Test Function
Bargraph blinks
“Trip” LED and “Alarm” relay activated
> Continuous monitoring
Test OK NO NO
Toroid input short circuit NO NO
Relay/Toroid connection break YES NO
> Activation of “Test” button
(Press (>1s) or external button)
Test OK YES YES
Toroid input short circuit NO NO
Relay/Toroid connection break YES NO

Pre-alarm function
When the measured current exceeds 50% of the threshold value, the pre-alarm relay changes state (if selected in this mode). Automatic reset to its original state if
30% lower than pre-set threshold.

Description of front panel
1 - Adjustment/setting I∆n
2 - Green “ON” LED
3 - “RESET” button
4 - Red “TRIP” alarm LED
5 - LED bargraph (% x I∆n)
6 - Configuration DIP switch
(x 4)
7 - “TEST” push-button
8 - Time setting
• With I∆n set at 30 mA, the timing is set at 0 (instantaneous) and can not be modified.
• The pre-configured factory setting for the device is 30
mA/0s. These values can be modified as needed for
operation. A plastic seal is provided with the device
in order to lock the protective cover and ensure the
settings.

* Dual voltage supply only available on 115/230 VAC model. For
Us = 115VAC, connect the supply to terminals 6 and 7. For the
other supply options, cable between 5 and 7.
The output relays are shown in the non-excited state (for
example, as if the auxiliary supply was not present)
The protective earth wire must not pass through the toroid. For
single-phase applications, only the phase and the neutral must
pass through the toroid.
** Cabling: For distances > 1 m, use a twisted pair for connection
between the relay and the toroid.
