6.6. REQUIREMENTS FOR THE USE OF THE DYNAMIC MANAGEMENT FUNCTIONALITY
OF THE CHARGING POWER
The charging station can be set to dynamically manage the charging power to the electric vehicle. To be able to
implement this logic, the electrical system must be prepared accordingly.
An energy meter (code GWD6812 or GWD6817) must be installed upstream of the electrical system that is able
to measure all domestic consumptions. This energy meter must then be connected to the charging station via an
RS485 line in order to permit communication on the Modbus protocol.
Refer to section 7.2.3 for more details.
DEVICE INSTALLATION AND CONNECTION
7.
Before proceeding with device installation, remove the packaging, paying particular attention to not damage the
casing.
Make sure there is no condensation inside the packaging. Otherwise, install the device only when it is completely
dry.
All the installation operations must be carried out in compliance with the directive in force.
All operations that involve moving large weights must be done by two people.
Connection must be carried out when the system is de-energised and by qualified personnel.
Scrupulously check that the device is not energised when accessing it inside.
To measure the lack of voltage, use dielectric gloves and safety goggles that are type-approved for electri-
cal risks.
7.1. GENERAL INSTALLATION REQUIREMENTS
• The device must be installed in a suitable environment that satisfies the information described in chapter “6.
Preparation for device installation” . Furthermore, the elements used in the rest of the installation must be com-
patible with the device and compliant with the applicable law.
• The ventilation and work space must be suitable for the maintenance operations according to the directive in
force.
• The external connection devices must be suitable and observe the distance established by the directive in force.
• The section of the connection cables must be suitable for the maximum current intensity.
• The system must have everything necessary to guarantee the proper operation of the charging station based
on the preferred charging mode that was selected. If this is not guaranteed, station operation will be limited or
will not function.
