Safety advice
Please pay attention to the following
safety advice in order to avoid danger
and damage to people and property.
This product is to be used in accor-
dance with its intended use only (see
pages 2 and 3).
The device is to be operated on
safety extra-low voltage via the
iSolar VBus®.
The surface material is susceptible to
scratches.
Avoid scratches on surfaces when
arranging the device. Errors and technical changes excepted.
The Smart Display SD3 is designed for simple connection to iSolar controllers
via the iSolar VBus®for visualisation of the data issued by the controller: col-
lector and store temperatures as well as energy yield of the solar system.The
use of high-efficient LEDs and filter glass assures a high optical brilliance and
good readability - even in poor visibility conditions and at a larger distance.An
additional power supply is not required.

1. Installation
The device must only be located in dry interior
rooms. It is not suitable for installation in hazardous
locations and should be protected from electroma-
gnetic fields.
1.1 Mounting
Wall mounting
The wall mounting of the SD3 has to be carried out using
the enclosed high-grade steel bracket.
1. Hold bracket to the desired place on the wall. Mark
drilling holes on the wall and drill holes with a 6 mm
drill.
2. Insert dowels and attach the bracket to the wall with
the screws (accessory bag).
Place the SD3 in the middle of the bracket.
Use as table-top unit
Insert wooden rod into the lower hole on the rear side of
the housing.
The SD3 can now be placed to the desired place.

2. Connection and commissioning
The iSolar Smart Display SD3 is designed for simple con-
nection to iSolar controllers via the iSolar VBus®. The bus
cable can be extended with a two-wire cable (bell wire).
The cable carries low voltage and must not run together in
a cable conduit with cables carrying a higher voltage than
24 V (please pay attention to the valid local regulations
such as VDE regulations for Germany). The cross section
must be at least 0.5 mm2and the cable can be extended up
to 165 ft. in the case of a single connection.
Note:
Protect susceptible furniture surfaces against scratches.

Note:
When several additional modules are used simultaneously, an
additional power supply of the modules might possibly be re-
quired.
VBus terminal
strain relief
The Smart Display SD3 can be operated in parallel with a
controller and additional modules via a bus line.
Connect the connection cable with stripped ends and
any polarity to the VBus®-terminals at the rear side of the
SD3.
Pass cable through strain relief.
During commissioning, the Smart Display SD3 carries out
an initialising phase.After this test the following indications
are shown:
• SD3 in the upper display
• Software version in the display in the middle
• Date of software version (YYMMDD) in the lower dis-
play
Afterwards, the SD3 receives data packets from the cont-
roller.The progress is indicated in the lower display.
Afterwards, the SD3 is ready for normal operation.
Note:
If no indication is shown in the display, please check the connec-
tion at the VBus® terminals.
