ELECTRICAL CONNECTIONS
The electrical connections should be executed all on the housing base.
The details of the connections to the mains, the two batteries, the AUX input and relay output
n.9 are illustrated in
outputs are illustrated in
The terminals are of "polarized inlet" type (1). We suggest to use
lugs adequate to the conductors (2) and to fix the wires to the box
structure to avoid excessive stress to the circuits and to the
terminals. Use a screwdriver (3) with the right dimensions.
Considering that, it should be normal procedure disconnect power to the electronic equipment when
installing, or changing the connections, or when disconnecting or connecting expansion cards.

WIRING CABLES
CONNECT THE FLAT CABLE
Only if necessary, for maintenance or installation requirements, the housing cover can be
separated from its base, first remove mains power and remove the batteries, then disconnect
the flat cable, press on the two side tabs as shown in
cover from sliding hinges (press fit). To reconnect it, proceed in reverse order and after
hanging up the lid hinges, push the flat cable into the connector, respecting the polarization,
the two levers close automatically locking it. Only then you can reconnect power supply.
BATTERIES: Inside the housing, it can also accommodate two 12V/1.3Ah Lead batteries connected in
series (Fig.5) to assure the system powering in case of mains blackout.
The battery life is about 60 minutes with No.8 sensors, but each detector in less increases the
autonomy of about 8 min.
(The batteries are not included in the delivery, but are available on request). If required, to
increase the autonomy, No.2 12V, 3Ah or 7Ah batteries connected in series can be used, but
due to their size, they must be installed outside the control unit.
Considering that each detector absorbs 0.1Ah from the battery, the autonomy, with 8 detectors,
becomes: about 2 hours with 3Ah batteries (each sensor less increases the autonomy by about
20 min) and about 5 hours with 7Ah (each sensor less increases the autonomy of about 50
minutes).
CABLE GLANDS: the lower side of the housing has 13 inputs designed for metric cable glands (ISO
pitch
1.5 mm). No.10
are for glands M16x1.5 mm
for glands M20x1.5 mm
These passages are closed, but they are not
requirements, they must be drilling. To facilitate the operation, they have a centering for the drill bit.
Please, pay attention not touch the tip of the internal circuits or the power supply cables
To guarantee the degree of protection of the enclosure, it is recommended to use cable glands with
protection IP55 or higher.
