Introduction
The CityEV Safevolt® 50
The 18th edition (BS7671) and latest edition of the IET code of practice introduces strict conditions for
electrical installations of charge points on PME installations, which reflects the majority of premises in the
UK. The CityEV Safevolt 50® alleviates the needs for costly and disruptive site works such as installing
ground rods or impractical isolation transformers when installing single phase EV charge points.
The CityEV Safevolt® 50 allows single phase charge points to be simply installed on existing PME systems
and be compliant with 18th Edition Amendment 1 recommendations and IET Code of Practice for Electric
Vehicle Charging Equipment. There is no need to convert to TT or install an isolation transformer.
Safevolt® 50 Operation
The Safevolt® 50 status indicators are shown and described below.
During normal operation, the green
OK
LED will show a steady green indicating that the output is on and
the charge point is connected.
If a PME fault condition is detected the red
FAULT
indicator will light and the charge point will be
disconnected from the L, N and E conductors, the Green
OK
LED will be off indicating that the output is
isolated.
When the PME fault is rectified the unit will automatically reconnect the charge point.
