A dedicated smartphone APP and WEBAPP make it easy to use, returning a summary of all dispensing
operations.
CAUTION: ambient conditions for use
Ambient temperature: min. -10°C / max. +40°C
Relative humidity: max 90%.
92 IMPROPERUSE
CAUTION: flammable liquids and explosive atmospheres
MC BOXdc B.SMART has not been designed to comply with the ATEX directive or to operate in
potentially explosive atmospheres.
Do not install the MC BOXdc B.SMART in a potentially explosive location.
The system was not designed for dispensing of petrol, flammable liquids with flash point <55°C/131°F,
or for operation in environments with potentially explosive atmosphere.
The use in the above mentioned conditions is forbidden.
CAUTION: improper use
It is strictly forbidden to use the system for purposes other than the ones indicated. Any other use

93 REASONABLYFORESEEABLEMISUSE
The smartphone is an indispensable tool for MC BOXdc B.SMART to set up and record the dispensing
cycles managed by the system, but it is forbidden to use your mobile phone near the transfer pump when
refuelling operations are under way.
CAUTION: Use your smartphone only and exclusively to connect, authenticate and link your device
to the dispenser. When refilling the vehicle, even with non-flammable liquids, the use of the telephone
is in any case strongly discouraged as it can cause distractions that can be dangerous.
10 INSTALLATION
FOREWORD
MC BOXdc B.SMART can be installed outdoors.
However, it is advisable to shelter it under a canopy to ensure a longer life and provide more comfort when
refilling in bad weather. Installation of the transfer pump must be carried out by specialised personnel and
carried out according to the instructions provided in this chapter.
If MC BOXdc B.SMART is not sheltered under a canopy, a “display cover” is provided as protection.
NOTE: It is also suitable for use in wet locations

11 ELECTRICAL CONNECTIONS
The electrical connections must be carried out in a workmanlike manner by specialised personnel, in full
compliance with the regulations in force in the country of installation and with the instructions in the
electrical diagrams in this manual.
CAUTION: the MC BOXdc B.SMART is NOT equipped with circuit breakers; it is therefore essential
to install an electrical power supply panel upstream from MC BOXdc B.SMART, equipped with a
circuit breaker / disconnector with a current rating suitable for the power feeding line and a suitable
RCD for the type of electrical load.
It is specified in detail that:
-a switch or circuit-breaker must be included in the installation;
-it must be suitably located and easily reached;
-it must be marked as the disconnecting device for the equipment.
CAUTION: The power supply panel equipped with switch or circuit breaker must be near the
equipment and the disconnecting means shall disconnect all current-carrying conductors.
CAUTION: before accessing the electrical parts, make sure that you have disconnected all the main
switches that energise the unit.
The operations required for correct wiring are described below:
• Controller PG connection.
• Power input (pump motor and board) and motor output cabling.
• Connector for: 24 Vdc service power supply, nozzle contact, level contact.
• OCIO connection on RS485 (if used).
• Connection for interfacing with other controllers via CANbus.
CABLEGLANDCONNECTION
The cable glands to be used for the various signals are indicated in the picture in order to obtain an
optimised cable route inside the controller.
1. Motor output.
2. Pump power supply input.
3. Board power supply input.
4. Pulser input.
5. Level contact.
6. Nozzle contact.
7. RS485 data line / CANbus line.
CAUTION: Use copper conductors only for
wiring.
