•
Industrial quality electrical receptacles should always be installed by qualified electricians in accordance

with national and local codes and regulations.

•
Receptacles from the supplier Hubbell are recommended for their industrial quality and ability to

handle high current for long periods of time (see Figure 1)

•
Hubbell HBL9450A = NEMA 14-50 Receptacle (4-prong)

•
Hubbell HLB9367 = NEMA 6-50 Receptacle (3-prong)
•
A 50-amp branch circuit should use minimum 6 AWG, 90°C-rated copper wire for conductors supplying

level 2 Porsche charging hardware plugged with a NEMA 14-50 or 6-50 supply cable
•
Receptacle terminal screws must be tightened to manufacturer specifications

•
This is an often-overlooked step of the installation process
•
The use of ferrules on the supply conductor wiring is recommended to further safeguard the connection at
the receptacle
•
110V Charging is for emergency use only. The relatively high current (8A to 10A) loads household circuits

and receptacles for an extremely long time

•
Charging hardware will normally reach high temperatures during prolonged use

•
High ambient temperature may cause stopped, slowed, or derated charging sessions

•
The optional Charging Dock (7PP.915.706.A) traps multiple heat sources (receptacle, plug, supply

cable, charge control unit, and part of the vehicle cable) and may exacerbate charger derating or

stopped charging sessions especially when exposed to direct sunlight.

•
The optional 7.5m vehicle cable is often wrapped around the charging dock. This further heats the

charging dock during/after prolonged use, especially if the vehicle is parked close to the charging

dock where less vehicle cable is needed.

•
The 10 AWG supply cables are tested and certified for use in US and Canada, and may differ from

other cord-and-plug EVSEs readily available in the market

•
It is recommended to install or relocate installed charging hardware away from vehicle heat sources

or heat exchanger exhaust air (for example, away from the Taycan front wheel opening)
Reading Diagnostic Trouble Codes (DTCs) from the PMCC and/or PWCC
Hardware needed:
•
For PMCC Diagnosis

•
PMCC Power Supply Cable (either 110V or 208-240V supply cable will work)

•
PMCC “ICCPD” (the main charger unit)

•
A PC or Smartphone
•
For PWCC Diagnosis

•
A PC or Smartphone
Accessing DTCs in PMCC and PWCC:
1.
Power up the device

a.
NOTE: If ‘energy saver’ mode is active, it will go to sleep and not be remote accessible after a few

minutes. Recommend switching off ‘energy saver’ mode during diagnosis.
2.
Use the charger controls to access Network Settings -> turn WiFi On and Hotspot On

a.
Write down the PMCC/PWCC Hotspot Name and IP address
3.
Using a PC or Smartphone, search for available WiFi networks and connect to the Hotspot (e.g., Network:
ICCPD-000*SERIALNUMBER*)

The 110V supply cable (NEMA 5-15) provided with Porsche hardware includes a temperature sensor. A
temperature sensor is integrated into the newer part number variants of the 208-240V supply cables
(NEMA6-/14-30/-50). With this temperature sensor, devices with compatible SW_C and/or SW_P are able to
monitor plug temperature and derate/switch off in the event of overheat.

The PMCC Web App - Customer Service Operating Manual, page 8, provides an indication on “Service
derated” messages (diagnostic background requested for messages and how they might relate to Event Log DTCs):
Service derated - This list indicates which sensors have restricted charging capacity due to overheating:
— 0: Overheating microcontroller
— 1: Overheating relay
— 2: Internal overheating
— 3: Overheating infrastructure cable, sensor 1
— 4: Overheating infrastructure cable, sensor 2
PMCC Event Log and DTCs
•
Detailed environmental data associated with ICCPD faults is typically found within the Event Log accessible

via the Web App [Customer Service --> Settings --> Service --> Event Log]
•
DTCs can also be read out as a Fault Code using the PT4G and special tool VAS 611 009, but with the fol
lowing discrepancies

•
Fault Titles may be incomplete, unclear, and/or not in English

•
Fault Environmental Data stored at the time of the fault occurrence (see Figures 5-7) may not be

relatable to a corresponding Working Log

•
Figures 5 and 6 show the PT4G fault memory; Figure 7 shows the Working Log

Note: The Time/Date Stamps of all DTCs in Passive Event Logs is the Time and Date when the DTC

was read out, not the Time and Date the error occurred. Therefore, additional information about

which error occurred at which time cannot be determined from this DTC information. This is a veri
fied bug in the diagnostic information; no bugfix is communicated at this time. More specific descriptions

and temperature thresholds for each DTC can also be found in GFF using the GFF Fault code in Figure 7.

Example: Charger Derating Due To Internal Overtemperature
The ICCPD is equipped with various temperature sensors and function monitors. If the de vice detects overheating,
for example, then charging current can be automatically reduced for a period of time.
Example Case:
The PMCC was left in direct sunlight while charging at 40A / 9.6 kW. The device automatically derated to 0.0 kW
charge rate and displayed the red “Limited service” message shown here. 1 minute later, the device automatically
increased charge rate to 6A / ca. 1.42 kW and presented as indicated in the “Derated” screen shown here. The device was then moved from direct sun to shade and proceeded to automatically increase charge rate until it returned
to 40A / 9.6 kW. The total time period for the entire derating session was 13 minutes and is indicated by the graph
in Figure 8 from the PMCC Web App.
