Set Dial Position (If Needed) - Nuvve EVSE-B-P Series Installation And Setup

Set Dial Position (if needed)

• Note: The position of the dial (rotary switch) controls a signal from the Nuvve PowerPort
to the EV that should limit how many amps any car plugging in to it will draw.
• To change this setting, first, access the dial:
• With the power off, remove the green "VEL" board, held down by four small screws and
a pull-out 54-pin connector (requires a firm pull). Turn VEL board over.
• Find the rotary switch, with positions 0 through F (see figure, below). As manufactured,
it should be set to "F", meaning that the manufacturer setting has not been altered.
• Determine your installation's "Breaker Size" and "Cordset Rating". In the table, pick a line
that is not greater than either. For breaker size, be sure to choose the correct column,
either for a US NEC breaker or UK/EU breaker.
• Set the arrow of the rotary switch, using a small flathead screwdriver, to point the arrow
to the number or letter in the column "Dial Position" below; this sets the maximum
Amps that the EVSE will allow the EV to charge.
• If changed, use a permanent marker to update the input and output Amp ratings on
the label on side of the case. (An example of this label is shown above.)
• If EVSE-B is installed in any of the countries CH, DK, FR, UK, where national codes
prohibit automatic retry after a ground fault, the installer must ensure that dip switch 4
is set to "on". The "on" setting prevents any automatic retry—thus the user must remove
the cable, wait, and plug back in to achieve a retry after fault.
