3.2.2 Differing requirements for the fulfillment of „Z.E.-Ready®“ (Renault)
 For the case where the internal switching element (contactor) is no longer able to open, an
additional switch-off capability must be realized. This can be realized with the switch con-
tact output X2 (for details, see chapter "Switch contact output [X2]").
 No 13A charging cables may be used.
 For 3-phase connection of the KeContact P20, at least a fault-current circuit breaker RCD
type A with DC fault current detection (>6mA) or a fault-current circuit breaker RCD type B
must be used.
 Renault recommends the selection of the line circuit breaker according to the following ta-
ble:
Preadjusted charging current
value (DIP-switch setting)
Line circuit breaker

The nominal current of the selected line circuit breaker must not exceed the value on the
type plate. If the preadjusted charging current setting and the nominal current are equal, in
particular the temperature in the switching cabinet must be considered (thermal derating of
the line circuit breaker).
Electricity supply earthing system requirements:
 In TT and TN systems, the ground resistance of the installation must be lower than
150 ohms.
 In IT or TT systems with ground resistance greater than 150 ohms, an isolating transformer
has to be placed in the EVSE (Electric Vehicle Supply Equipment) upstream installation.
This transformer must then be fed into a TN earthing system for which the above men-
tioned criteria apply.
 Electricity supplies with IT earthing systems are prohibited.
