Case - Mounting

The SCADA Central Station must be installed b y qualified personnel in accordance with local regulations (NF C 15-100 in France,
NEC in the U.S., etc.)

The case must be installed in a fire-resistant enclosure. This enclosure must stay closed during normal operation; it is only accessible
by qualified personnel and requires a key or tool to open it. The case is mounted on a standard metal DIN rail (35 mm).

The DIN rail is required to be connected to Ground; the grounding connection is carried out automatically when
the case is mounted.

To remove the case from the DIN rail, the user will use a screwdriver-type tool.
If the fasteners become unfastened, the user must make sure to replace th em to prevent the case from

The I/O modules have a separate 24 Vdc power supply, independent of the compact case: it is not backed up by the battery.
Simply connect a single I/O module to a 24 V

The power supply to the case can be backed up with a 12 VDC lead battery, either 4 Ah or 12 Ah.
A periodic battery capacity test is performed automatically. The RTU manages the charge and performs continuous self-testing

• Prot ection against overloads

• Automatic shut-off in the event of a short-circuit

• Prot ection against reverse polarity.

• Battery detection.

• Pr otection against deep discharges (threshold at 10.2 V).

When powering via backup battery, the voltage must be at least 12 V ±200 mV to start up;
When the product has started, its operating range is between 10.2 V and 13.8 V. Furthermore, when the RTU
power supply is voluntarily cut off for a long period (typically 48 hours or more), it is necessary to disconnect

Powering via solar panels

24V solar panel controllers are connected directly to the GND and +24 V

Use of SunSaver controllers is recommended: contact our t echnical
sales departmen t to ensure se lection of t he appropri ate controller

type (6, 10 or 20) and sizing of the solar panel according to the
geographic location of installation. Make sure to follow the
recommende d installation in dicated in the manua l provided with
the controller: assembly in vertical position, execution of the

connections in asc ending order of the terminal strips 1 to 6 on th e
diagram opposite (ba ttery, solar panel, then the RTU last), position of
the jumper for the use of an open battery, etc.

DO terminal strip:

Connection of DOs

DOs are 12 V / 24 V AC/DC ’very low voltage’ voltage-relay type digital outputs: they are compatible with 24 V relays and control panel
indicator lights.

By default, and following a total power cut (24V and Battery), DOs are in their 'open' state (idle state = 0).
In case of product reinitialisation, the state of each DO is retained (no forced return to the idle state).

The user defines the ‘bistable’ or ‘impulse’ control type when configuring each DO data point.
When a DO is configured to control the ‘Watchdog safe ty’ feature; this output is reinitialised according to inverse logic (the output is

in the closed state if no default; it switches to t he open state if a default is pres ent). This 'Watchdog' output is very usef ul for controlling
power supply and for the proper functioning of the RTU (see § ‘Data processing – Operational safety’).
