3�- DEVICE INSTALLATION
3.1.- PRIOR RECOMMENDATIONS
In order to use the unit safely, it is critical that those who handle it follow the safety
measures set out in the standards of the country where it is being used, use the
necessary personal protective equipment and pay attention to the various warn-
ings indicated in this instruction manual.
The REC 3unitmustbeinstalledbyauthorisedandqualiedstaff.
Also, it is critical to keep the cables in perfect condition in order to avoid accidents, personal
injury and damage to installations.
The manufacturer of the unit is not responsible for any damages resulting from failure by the
user or installer to heed the warnings and/or recommendations set out in this manual, nor for
damages resulting from the use of non-original products or accessories or those made by other
manufacturers.
If you detect any operational faults in the unit or in its protection system, remove the unit from
service.
This unit has been designed for easy replacement in case of malfunction.
Disable the automatic reclosing function and disconnect the main protection de-
vice before handling active parts.
Please contact the after-sales service if you suspect that there is an operational
fault in the unit.
3.2.- INSTALLATION
Do not use the unit until it is fully installed.

3.3.- CONNECTION,REC 3 2 poles y REC 3C 2 poles
The REC 3 must be connected to a power circuit protected with miniature circuit breakers, in
accordance with its power supply range and consumption. In turn, the power circuit must be
ttedwithacircuitbreakerswitchoranequivalentdeviceinordertobeabletodisconnectthe
unit from the power supply mains.
In single-phase installations (phase and neutral, L and N), the supply cables are connected up
top and the cables from the protected loads are connected below.

4�- START-UP
Once the unit is installed you must carry out the following start-up sequence for it to work prop-
erly.
4.1.- AUTOMATIC MODE
If the unit is going to operate in automatic mode, see Section “5.2.- AUTOMATIC” . The start-up
sequence is:
1�- Put the mode selector switch in Manual Mode (OFF).
2�- Lift the RCCB cover.
3�- Put the RCCB contact in ON mode.
4�- Lower the RCCB cover.
5�- Put the mode selector switch in Automatic Mode (ON).
Note: The switch has an M2 hole where you can attach a seal or a padlock to block access to
the RCCB and any other attempts at manual reclosing (Figure 10).
Figure 10: Switch's M2 hole to seal access to the RCCB�
4.2.- MANUAL MODE
If the unit is going to operate in manual mode, see Section “5.1.- MANUAL” . The start-up se-
quence is:
1�- Put the mode selector switch in Manual Mode (OFF).
2�- Lift the RCCB cover.
3�- Put the RCCB contact in OFF mode.
4�- Lower the RCCB cover (optional).
17
Instruction Manual
REC 3 - REC 3C

5�- OPERATION
The unit has two operating modes, manual and automatic, which can be selected using the
mode selector switch.
5.1.- MANUAL
The REC 3 can operate in manual mode as if it were a standard RCCB.
To operate in this mode, the mode selector switch must be all the way to the right, in OFF
position, to disable the unit's automatic reclosing device. (Figure 11)
The RCCB must be reclosed manually.
The AUTO and REC LEDs are off.
Figure 11: REC3 in manual mode, with mode selector switch at OFF�
5.2.- AUTOMATIC
To operate in Automatic mode, the mode selector switch must be all the way to the left, in ON
position, to enable the unit's automatic reclosing system.(Figure 12)
The AUTO LED is constantly lit and the REC LED lights up based on the unit's status.
18 Instruction Manual
REC 3 - REC 3C

Figure 12: REC 3 in automatic mode, with mode selector switch at ON�
The REC 3 allows two modes of automatic reclosing:
- M Mode, by insulation, (REC 3 of 30 mA) the unit does not reclose until the leakage
has disappeared.
- T Mode, by time, (REC 3 of 300 mA) the unit reclose the system, independently of the
leakage.
By default, automatic reclosing method by time.
5�2�1�- RECLOSING DEVICE BY INSULATION, M MODE
Following a time delay after a disconnection due to an RCCB trip, the REC 3 makes a measure-
ment to check whether there is a leakage current. If there is none it begins to reclose.
The REC 3 attempts a maximum of 3 measurements to check the leakage current; following
this the unit stays locked and does not automatically reclose.
If the time between a reclosure and the next trip is greater than the restart time, the reclosing
attempts start over at zero.
The delay and restart times depend on the number of attempts the reclosing device has made,
as shown in Table 5�

Reclosures

Delay Restart Delay Restart Delay Restart

The leakage current will be supervised by measuring the resistance downstream of the tripped
RCCB.
19
Instruction Manual
REC 3 - REC 3C

5�2�2�- RECLOSING DEVICE BY TIME, T MODE
Following a time delay after a disconnection due to an RCCB trip, the REC 3 begins to reclose.
If there is leakage, the unit will trip..
The REC 3 attempts a maximum of 3 reclosures; following this the unit stays locked and does
not automatically reclose.
If the time between a reclosure and the next trip is greater than the restart time, the reclosing
attempts start over at zero.
The delay and restart times depend on the number of attempts the reclosing device has made,
as shown in Table 5�
5�2�3�- RESTARTING THE RECLOSING SYSTEM METER
There are two ways to restart the internal reclosing system meter:
- Manually, by moving the mode selector switch from ON to OFF position and back to
ON.
- Automatically, when the restart time elapses after the last reclosing without tripping
again.
5�2�4�- RESET
In case of blocking of the REC3, the reset sequence is:
1�- Put the mode selector switch in Manual Mode (OFF).
2�- Lift the RCCB cover.
3�- Put the RCCB contact in ON mode.
4�- Lower the RCCB cover.
5�- Put the mode selector switch in Automatic mode (ON).
Note : The switch has an M2 hole where you can attach a seal or a padlock to block access to
the RCCB and any other attempts at manual reclosing.(Figura 10).
