2. WARNING - INSTALLATION INSTRUCTIONS AND USER RESTRICTIONS
2.1 WARNINGCORRECT
DEVICE’S OPERATING
WAIT AT LEAST 3 SECONDS BETWEEN EACH POWER-OFF AND POWER-ON.
Before installation and using the device, please read carefully the user manual.
POWER- ON
Before turning-on the device, please perform all the necessary connections according to local regulations in place.
Some parts are connected to the power supply.
•The wiring and the up keeping have to be carried out by powering off the device.
•The non-observance of it may cause death risk. Please make sure that there is no accidental connection.
•Please make sure that the power supply to which the device is connected is in conformity with the label’s
data (nominal values) before connecting it.
•The installation of the device must be performed by an authorised service provider or certified electrician
only.
•In case of doubt about the metering’s safety, please do not use it and replace it.
PROTECTION
Please make sure that all the accessible metallic parts, which can become live in the event of an insulation fault are
permanently and reliably connected to the device’s earthling terminal.
Also please make sure that the machine’s earthling terminal is connected to an efficient earthling protection.
EXTERNAL COMPONENTS
The insertion of external components on the board, necessary to ensure an adequate reduction of the interference,
shouldn’t have to affect the device’s safety, i.e. they have to be of adequate type and value.
COMPONENTS
In case of necessity, we reserve the right to substitute electronic parts with alternative components, having the same
electrical data and standards.
SOFTWARE
In case of necessity we reserve the right to amend the described procedures during the software’s engineering phase,
in order to simplify an easier or more user-friendly usage of the device or a more coherent development of the
software, without modifying the device’s functional aspects.
2.2. INSTALLING INSTRUCTIONS AND USING LIMITS
WIRING
The board’s wiring has to be performed considering the necessity of keeping the low-tension cables separated from
the high tension ones.
The device has to be placed far from other equipment, like pumps, solenoid valves, remote-control
switches, motors in general, neon lamps, as their functioning could affect the electromagnetic ambient.
AMBIENT
The device has to be placed as far as possible from heating sources and from excessive humidity, or where there
might be, for any reason, any condensation forming.
DIRT
The board inside the machine has to be adequately protected against dirt. As per definition "in general, the interior of
an appliance having a reasonably dust-proof enclosure is considered to be protected against deposition of dirt" (EN
60335-1).
REMOTE- CONTROL SWITCHES
If external remote-control switch is used for a loading command, the connection of RC filters (or a different device)
could be necessary to suppress the interference issued during the loading switching.
SUPPRESSORS
In case remote-control switches and/or solenoid valves are used, it may be useful to place a varistor on their coil to
limit tension peaks, which may arise during switching over. The worst the boards’ operating ambient is protected
against humidity, high temperature and dirt (dust, dust soaked with other substances, condensation…), the most
important this solution is.
