They are dimensioned to withstand the required impulse withstand
voltage and to withstand the long-term continuous operation. A
charging station operates with an RCD device, which is designed to
protect against the risks of electrocution and in addition offers
protection against fire caused by earth faults. It is a sensitive safety
device that switches off electricity automatically if there is a fault.
The ingress protection class of IP54 proves, that the enclosure of the
charging station is protecting the internals against ingress of solid
objects, permits only limited ingress of dust and is protected against
water splashes from all directions. Impact protection, of at least IK10
states, that the charging station can withstand impacts, equivalent to
5 kg dropped from height of 40 cm. As required, tests for the IK class
were performed before testing of IP class.
FIRE SAFETY MEASURES
At the location of car charging, the fire hazards and thus the threats are
increased during the process of charging. The overall design of our
products is made on the basis assumption that the fault could occur on
any element of the system. Either in the electrical wiring of power
supply, in wiring or inside of the charging station, or in the car.
The enclosure and the assembly design are made in such a way that the
contact of the user to hazardous parts is not possible. In the event of
fire, metal enclosure would constrain a fire and would not allow the
propagation outside of the enclosure. Regarding the fire safety in all
possible cases of installation, that are out of control of our company,
several recommendations are listed:
• The charger must be installed outside the hazardous area.
• The installation of the charging station can be performed only by
professional electrician and must comply with the installation
manual and local installation rules.
• Ensure that there is enough space to manoeuvre vehicles into
their designated charging areas and that in event of fire the
escape and rescue routes are not obstructed.
• No flammable or combustible material should be stored within
the charging area.
• Provision of suitable portable fire extinguisher at the location of
the charging station is proposed.
• When the charging station without integral RCD device is
installed, the proper RCD device should be installed in the main
electrical cabinet.
