APPEARANCE
The device is designed for
single-phase installation and
must be installed in accor-
dance with standards valid
in a particular country. The
device should be connected
according to the details included in this ope-
rating manual. Installation, connection and
control should be carried out by a qualified
electrician staff, who act in accordance with
the service manual and the device functions.
Disassembling of the device is equal with
a loss of guarantee and can cause electric
shock. Before installation make sure the con-
nection cables are not under voltage. The
cruciform head screwdriver 3,5 mm should
be used to instal the device. Improper trans-
port, storage, and use of the device influence
its wrong functioning. It is not advisable to
instal the device in the following cases: if any
device part is missing or the device is dama-
ged or deformed. In case of improper func-
tioning of the device contact the producer.

• Bistable lighting control Input rated in-
dicator – LED green,
• relay mode indicator – LED red,
• system releasing from the L/N or +/- li-
nes,
• TEST function,
• double-wire controll installation,

• monomodular casing TH35 DIN rail in-
stallation.
The bistable (impulse) relay 4028682
is used to control lighting or other devices
by means of monomodular pushbuttons
connected in a parallel way. Pushing any
button causes switching on or switching
off the devices connected to output termi-
nals. Using this system gives the possibility
of creating “intelligent” lighting control
systems.

MOUNTING, FUNCTIONING
1. Disconnect the power supply from the
mains by the phase fuse, the circuit-
-breaker or the switch-disconnector
that are joined to the proper circuit,
2. Check if there is no voltage on con-
nection cables by means of a special
measure equipment,
3. Install 4028682 device in the switchbo-
ard on TH-35 DIN rail,
4. Connect the cables with the terminals
according to installing diagram,
5. Switch on the power supply from the
mains,
6. Push the TEST button several times to
check the relay operation correctness.
The device is ready to work after swit-
ching on power supply. The relay opera-
tion correctness can be checked by pu-
shing the TEST button placed on the front
panel. The system should switch on and
off the load connected to its output termi-
nals. Mono modular pushbuttons can be
connected in a paralell way which enables
the lighting control from different places.
APPLICATION
CONNECTION
DIMENSIONS
Typical application:
The bistable (impulse) relay operating the
staircase lighting (e.g. indoor lighting) are con-
trolled by means of mono modular pushbut-
tons that can be connected in a parallel way.
The buttons can be placed in different places
which gives the possibility of creating univer-
sal lighting systems control. The bistable relay
cooperates with time relay PCM-04 (with set-
-ups: MODE=F, TIME=3, RANGE=2) and the
same gives additional function the central bi-
stable relay switch off (reset) by momentary
power cut.
