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 Lpd 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�

The device’s auxiliary supply must be protected with fuses or protection elements appropriate for the power supply range and consumption� Preferably the protection should consist of a small circuit breaker allowing the disconnection of the unit from the power supply in case of servicing�

3�2�1�- MEASUREMENT OF THE EARTH LEAKAGE CURRENT IΔ

The earth leakage current must be measured using the WG/WGS/WGC earth leakage transformers from CIRCUTOR�

The transformer terminals which should be connected to terminals 7-8 of the RECmax Lpd

(Table 4), are :

Table 3: Earth leakage transformer terminals�

Earth leakage transformer to connect in the RECmax Lpd

Model Terminals

WGC S1 - S2

WGS - WG 1S1 - 1S2

The external earth leakage transformer is necessary for the device to operate correctly� 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 Lpd display�

An incorrect or faulty connection of the earth leakage transformer means loss of the earth leakage protection and possible risk of electric shock�

When using the WG/WGS earth leakage transformers, the 2S1-2S2 terminals should not be connected to the RECmax Lpd nor should be short-circuited� They should be left at open circuit�

In case of a faulty connection of the earth leakage transformer or if this transformer is not compatible with the RECmax Lpd, the screen shown in Figure 1 will appear�

3�5�- DISCONNECTION OF THE DEVICE

If after wiring the RECmax Lpd you decide to have the protected line disconnected, you must disconnect the device manually by pushing the contact lever of the switch downwards and moving the mechanical lock (yellow sealable catch Figure 5) upwards� This eliminates any possibility of accidental reclosing

Figure 5: Mechanical lock�

Never manually lower the circuit breaker without previously enabling the me-

chanical lock (moving the yellow sealable catch, Figure 5, upwards)� This prevents accidental reclosing while handling the installation� On doing this, although the green LED is not on, the unit remains connected to the upstream auxiliary power supply and therefore precautions should be taken to avoid touching parts with voltage�

4�1�- OPERATING PRINCIPLE

RECmax Lpd is a device for protecting single-phase or three-phase electrical installations of up to 63 A in which a high continuity of electrical service must be guaranteed� The device has an automatic reset system after a trip, so it reconnects on its own after a period of time, with the installation recovering power without human operator intervention�

The basic functions of the RECmax Lpd are:

 Earth leakage protection (protecting people against electric shock and property against the

risk of re)

Protection against overloads and short-circuits with a circuit breaker�

4�8�- RESET LEVER AND MANUAL LOCKING

The device has a reset lever (see Figure 6), its default position is down� In case of reclosing, the motor lever is raised actuating the switch� After the reset, the motor lever returns to its downward position�

The device also has a manual locking system to prevent the possibility of automatic reclosing� The lever is sealable�

Reclosing of the device can be completely prevented through manual locking� The operation is performed by moving the reset lever downwards and moving the manual locking system (yellow catch) to the left�

In case of manual locking, although the green LED is not ON, the device is connected to the power supply� Therefore, there is a risk of electric shock if the power supply is not cut off�

4�10�- TRIP STATUS

The device may be tripped due to:

 Actuation of the protection due to an installation defect, whether the earth leakage

protection or protection against overloads or a short-circuit�

 Manual opening of the main switch, lowering the switch lever�

 Pressing of the TEST key�

 External order, after the EXT remote control input�

Whatever the case, if after the trip some maintenance check or action in the electrical installation is required, it is advisable to activate the mechanical lock to prevent accidental reclosing during operation�

If the trip was caused by actuation of the protection, NEVER reclose the switch manually, always do so by pressing the RESET key�

The trip gives rise to one of 2 possibilities:

 Automatic reclosing is possible  Automatic reclosing is not possible

4�10�1�- AUTOMATIC RECLOSING IS POSSIBLE

Immediately after the trip, the device begins a sequence of reclosing attempts with the programmed time intervals� In this situation the status indicators are shown in Table 14�

After an automatic reclosing sequence, the partial reclosing meters restart after 15 or 30 minutes after the last reclose, according to the value congured (see “6.2.1.- SDR: EARTH LEAKAGE RECLOSING SEQUENCE” and

“6.2.2.- SRM: CIRCUIT BREAKER RECLOSING SEQUENCE”)

4�10�2�- AUTOMATIC RECLOSING IS NOT POSSIBLE

Automatic reclosing may not be possible for one of the following reasons:

1�- Reclosing has been disabled when programming the device� The display will show the cause of the trip without the REC symbol�

The reset is only possible by modifying the Conguration of the device, see “6.2.1.- SDR:

EARTH LEAKAGE RECLOSING SEQUENCE” AND “6.2.2.- SRM: CIRCUIT BREAKER RECLOSING SEQUENCE”

2�- The number of reclosing attempts has been exhausted� The display will show the cause of the trip without the REC symbol� In this case, the reset is only possible by pressing the RESET key or by an external order of the EXT input� Reclosing the device with the RESET key or the EXT input restarts the partial reclosing meters�

3�- The device was tripped manually by pressing the TEST key� The display will show the “TEST” text, see “5.2.3.- TRIPPING WITH THE TEST KEY”� In this case, the reset is only possible by pressing the TEST key again�

4�- The trip was caused by the EXT remote control input� The display will show the “EXT” text, see “5.2.4.- TRIP DUE TO EXT ON/OFF INPUT” In this case, reclosing is only possible with another external order of the EXT remote control input�
