Pod Point Solo Unit
Installation Guide
RCD protection:
From January 2019 new Pod-Point's will inclu
6mA DC vehicle fault protection and only Type A RCD/
RCBO's are required at source, if the Pod-Point was built
earlier than this Type B RCD protection should be fitted
at source, the symbols printed on the RCD in figure 1 can
be used to identify the type of RCD protection.
Surge protection:
Guidance on requiremen
devices given In BS7671: section 443.
The Pod-Point is protected against transient over
voltages (+/-2kV Line-Earth and +/-1kV Line-Line as a
requirement of EN 61000-6-1), a direct lightning strike
carries a current of 30~ 200kA the Pod Points internal
protection would provide little or no protection in such an
event, likewise nor would an SPD rated less than 30kA. If
life support equipment or business operations could be
affected by a lightning strike central SPD protection is
advised if it does not already exist. The guidance on risk
calculation in section 443.5 of BS7671 in most cases is not
possible due to unknown location of any SPD already
fitted, length of cables to calculate Lp etc., it Is therefore
recommended a common sense approach is used on
choice of SPD (or if required).
Array systems:
The Pod-Point array system is designed to maximise
charging for several units connected to a limited supply,
To notify the Pod-Point of the total supply load a low
voltage signal provided by an array controller should be
hardwired to the point (connected to CON9 or J201). The
Pod-Point(s) require WiFi connection and commissioning
to enable the array features. For more details see:

Charging-Datasheet.pdf
Transformers
If a galvanically isolated transformer is required, it should
be placed upstream of the EVSE. The Neutral output
feed of the transformer shall be connected to EVSE
earth (creating a TN-S system). the PE taken before
any RCD and MCB (if 2 pole MCB is used), resistance
measured between the EVSE PE and this Earth must be
less than 100 ohms. Do not connect the output earth/
neutral of the transformer to a PME earthed system.
Upstream transformer RCD protection maybe of Type
AC (if fitted), downstream RCD protection is still required.
Transformers should be rated for 100% duty cycle at 10%
above rated charge current and should be located in a
dry well ventilated area.
Direct EVSE connection to an IT system is prohibited.

Isolation and switching for safety and
maintenance
To ensure that the Pod Point Solo unit can be "turned off"
to enhance security and enable maintenance activities,
a double pole isolator (or 2 pole RCBO) suitably rated
must be installed within the customer's property. An
isolator switch is a mandatory requirement for "new
builds", but optional for existing dwellings (at customer's
request), the switch should be mounted at a height of
between 500mm and 1500mm above finished floor level
to comply with regulation's. The switch should be rated
at 45 amps.
All installations must comply to BS7671: 2018 regulations.
Installation procedure
The Pod Point Solo has been designed as a wall
mounted device. The installer should confirm that the
wall that the unit is intended to be fixed to is structurally
appropriate for the mounting of the Pod Point Solo. The
installer should identify the construction of the wall, and
identify the correct and appropriate fixings to use.
• The Installer has a duty of care to ensure that the
Pod Point Solo unit is securely attached to the wall or
structure where the unit is intended to be operated from.
• Once the location and height of the Pod Point Solo
unit has been decided, the installer can begin marking
the wall with indicator points to locate the unit. Us the
back of the box insert as the drilling template for the 3
mounting holes (Fig. 3)
• NOTE: If any groundworks are required (cable
trenching or earth electrode fitment) it is advisable
to check if underground services could be present
before commencement, plans maybe available at:
linesearchbeforeudig.co.uk (free to domestic users).
Fig.3 Drilling template (box insert)
• Before drilling commences ensure that the installation
wall has been checked for electric cabling or pipework
with a suitable detector.
• It is highly recommended this is done prior to any
installation work commencement (drilling or fitting of
conduit etc) to allow the customer to visualise where
the unit will be once installed. Once the installation site
is marked up, confirm with the customer this meets
their expectations.

Additional parts required by
the installer:
1. 3x M8 80mm screws
2. 3x Wallplugs
3. 20mm IP56 or greater
gland for the conduit
entry into the rear unit
housing dependent on
the supply method
(20mm conduit, SWA
armoured cable, flexible
conduit etc.).
