Iris8 B Common Modular Terminal Block - Teletek electronics iRIS8 Installation Manual

4.1.2 Connection Diagram of Main Power Supply Unit and Back-up Battery
The connection between the accumulator battery and the main power unit has some special features. It is strongly
recommended to use only battery with electrical characteristics and dimensions pointed from the manufacturer. Before
connecting to the main power unit check the polarity of the battery. The battery cannot power up the panel before the
mains supply has been switched on. Connect the battery after the mains supply is turned on. If the battery is new, it will
take a few hours before its complete charging!
The charging of the accumulator battery is done at maximum current I=2A and charging voltage U < 13.8V.
•
Connect the 110÷230V AC power source to fuse terminal block as strictly observe the polarity.
•
Connect the red cable to the positive pole of the battery, and the black cable - to the negative battery pole. Both
of the cables are connected to the battery by means of a flat terminal lug Ø5mm or cable shoes.
•
Place the temperature sensor behind or under the accumulator battery to provide correct measurement the
battery temperature and calculation of the internal resistance value Ri.

4.2. iRIS8 B Common Modular Terminal Block

In iRIS8 B, the 110÷230V AC power source is connected to a special modular terminal, which provides the power
supply to the two independent main power supply units. The connection of the power units is factory done. The installer
must connect only the 110÷230V AC power source to the modular terminal.

Attention: Check the earth
connection cable before
switching on the mains power
supply – the connection must
be tight and stable to ensure
the correct operation of the
panel and accurate LED
indication on main power
source for possible problems
with earth connection of the
panel.
Before the mains supply is
switched on, check the
correct connection of each
loop, sounder or any other
input or output, and the earth
connection cable.
