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.

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 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.

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.

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

2 2

of 28 mm (inner diameter) 4-wire 35 mm of section, although it advisable is 25 mm . All connections

INSTALLATION AND STAR-UP

¡ IMPORTANT !

The unit´s protections systems might not be effective if the unit is used for purpose other than

those specifications by the manufacturer.

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.

change of status by changing from green to red.

Display event type messages or values

PREALARM SIGNAL. The LED green is blinking

betwen green and red.

BETWEN RECLOSURES. LED is blinking

LOCKED BY RECLOSURES. The yellow LED is

fixed. The equipment arrives al maximun number of reclosures established by the self-reclosing

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.

TRIP LOCKED BY RECLOSURES

Automatic (earth leakage fault or manual). Is shown on display

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.

MAIN RELAY PARAMETER SETTING

SETTING TRIP DELAY The message and two values appear on the screen after

pressing the button. The lowest value indicates the current set value and the highest is the

values to be configured which are displayed by pressing The selected value to be saved is

displayed by showing the message

SENSITIVITY SETTING The same operation as above setting is carried out by pressing

¡ IMPORTANT !

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.
