PRELIMINARY CONSIDERATIONS
CHECKS ON RECEPTION
On receving the instrument, check the following points:
- The unit's specifications are the same as those on your order.
- Check that the device has not suffered any damage during transport.
You can download more information from CIRCUTOR website, www.circutor.es
SAFETY PRECAUTIONS
The staff using or handling the unit must follow the common safety measures and warnings included in the
instruction manual.
The WRU-10 MT unit has been specifically designed for its installation in a electric board, enclosure to a
DIN rail or mounted in panel by means of accesories. It has a flashing green led (ON) when it is operation
and, therefore, it shows that there is voltage and current in the electronic circuit. The user must make sure
that the equipment is not conected to the power supply at all the times, even when the LED is not flashing.
INSTALLATION AND START-UP
The user must take into account and observe the informations and warnings included in this instruction
manual to guarantee the correct operation of the equipment and comply whit the safety specifications. The
equipment must not turned on until is fully installed in the electrical panel.
¡ IMPORTANT !
!
The unit´s protections systems might not be effective if the unit is used for purpose other than
those specifications by the manufacturer.
Disconnect the equipment from the power supply when the unit´ssafety protection systems are not working
or there are signs of a problem (in case of visible damage). In this case, contact a qualified technical service
or with our own technical service (TAS).
INSTALLING THE EQUIPMENT
DIN rail installation. On the inside of the hole must pass all live conductors supplyng electrical energy to
loads or part of the installation which requires it to earth leakage protection with this device. In single-phase
installation (phase and neutral, L and N), three phase - 3 wires (three phases, L1, L2 and L3) or three
phases - 4 wires (L1, L2, L3 and N). Depending on the level of wiring insulation can be pass through the hole
should be inside the electrical board. Please note that with the connected equipment, terminals and
opening covers or removing elements, can give access to dangerous parts to touch. The equipment must
not be used until it has completely finished installation. The unit must be connected to a power supply circuit
protected by fuses in line with the range and power consumption. In turn, the supply circuit must be
provided with a circuit breaker or equivalent device to disconnect the equipment from the mains. During the
wiring cable is advisable a section permitted between 1 - 1.5 mm2. A recommended torque of 0.5-0.6 N.M.
Cable Stripping Tools length 7 mm.

sequence. Red display shows the cause.
- No OF RECLOSURES. By short press on the display shows the number of reclosures by earth
leakage faults, partial and total number. The partial number are floating pages. In these pages
it can configure the self-reclosing sequence by press button.
RECLOSING THE EQUIPMENT.
- BY TRIP LOCKED BY RECLOSURES
1. Automatic (earth leakage fault or manual). Is
2. Manual reclose by pushing button RESET.
3. External reclose sytem by remote or communications signal. When it forces a trip by remote
signal, only it can reclose by another remote signal. In the case 2 and 3 the partial counters
of reclosures returns to a zero.
The relay only self-recloses after a trip by earth leakage current fault. The Test (red button) only verifies the relay trips
the protection. It recloses only by manual pressing RESET button.
