About PEN Fault
The TruePEN system removes the need to install a dedicated earth
for the charger.
In the event of a fault, the system will break all power cable
connections between the charger and the vehicle.
A PEN fault is most commonly seen as either, an undervoltage
session to the HomEv system in real time.
Results can be identified via the status indicators.

7
or an overvoltage entering the charger from the mains supply.
Following initial power ON, the TruePEN system monitors the supply
voltage for 5 seconds and determines if the voltage is within normal
operating parameters.
If within limits, TruePEN allows the connection of Live, Neutral
and Earth to the vehicle and continues to monitor the supply. If the
voltage goes out of limits (below 207 Volts or above 253 Volts) for
a continuous period of 5 seconds, this could be caused by a PEN
fault. The TruePEN device will activate ('trip') and isolate Live,
Neutral and Earth to the vehicle.

wall.
• Make sure the positioning template is level
and vertical.
• Use the holes in the positioning template
as guide to mark where the expansion
pipes will be secured.
• Drill three Φ 6 * 35 mm holes on the wall
and insert the the expansion pipes.
• Insert two M4*32mm self-tapping screws
into the upper two expansion pipes and
leave a 5mm gap between the screw head
and the wall.
Mount charger body
• Test t the charger onto the screws and make sure there are no
tting issues.
• Hang the charger on the wall by inserting the two notches on the
upper back of the charger into the two screws.
• Use the key to unlock the lock on the right side of the charger
and open the cover.
• Find the screw hole at the lower part of the charger then insert
the self-tapping screw into it and tighten to secure the charger
body onto the wall rmly.

Wiring
Congure wi network for your
charger
Step 1: Activate the charger's hotspot
Activate the hotspot of the charger by restarting the power supply.
NOTE: The hotspot of the charger remains available for 15 minutes
after the charger is restarted.
Step 2: Establish a communication between charger and your
phone

10
Switch your phone to airplane mode, and make sure that the WLAN
is enabled.
Charger WiFi Phone
The charger will send
out a hotspot after it
is restarted
WiFi name: the serial
number of the charger
WiFi password:admin123
Select the WiFi hotspot
send out by the charger
and enter the password
to login.
Step 3: Login
To access the LOGIN page, enter the IP address 192.168.4.1 in a
browser, followed by the 4-digit network password (PIN number).
Note: The PIN number can be found on the cover of the charger,
or in at the last page of the user manual, please remember the PIN
number and remove the PIN number sticker for the sake of security.
Step 4: Congure network
After logging in, and you will be prompted with the following
interfaces:

11
Select the wi for your
charger to connected to.
Enter the wi password
Enter the server address
Select the grid type
Click to complete the
Network conguration
Click and you will see interface as shown on the right side
above, then enter the information to congure the network.
Note: Your charger will automatically restart once the network
conguration is complete, ending communication between your phone and
the charger, at this point, your phone may automatically join to additional
wifi hotspots, preventing you from accessing the network configuration
interface. As a result, before accessing the network conguration interface,
please ensure that your phone is connected to the charger's wi hotspot.
Step 5: Set Charger
Click and you will enter the interface to set the load
balance, select the charging mode between network mode and plug
& play mode, and set the maximum charging current.
Note: To set the load balance, it requires you to install a CT or/and
a meter to measure the current of the charger as in such a way to
achieve the load balance.

Maintenance
IMPORTANT: National/regional legislation may override any
maintenance advice provided below. Always comply with the
legislation.
NOTE: In the event of a hardware issue, always contact your
installer rst.
• If damage has been sustained to communications devices and/
or other 'Smart' components, please contact support center.
• Damage caused to the equipment by misuse, lack of
maintenance, inappropriate maintenance or modication are not
covered by the manufacturer warranty.
IMPORTANT: It is the owner's responsibility to make sure the
charger is maintained in a safe and useable condition. Failure to
maintain the equipment may invalidate the warranty. If required,
consult/contact an appropriately qualied electrical engineer.
1. Regularly clean the external surfaces of the equipment with a
damp cloth.
Depending on the working environment, external cleaning
and inspection may be required more regularly than other
maintenance tasks.
CAUTION: Equipment Damage
To avoid damage to the surface finish, and/or internal
components do NOT use:
• Abrasive materials.
• Mineral or petroleum solvents / degreasers.
• Hose pipes, Jet washers or Steam cleaners.
2. Regularly inspect the exterior of the equipment for visual damage.
• If damage a󰀨ects safety, isolate the equipment and prevent its
use until appropriate repairs have been completed.

17
3. If required, remove debris from around the charging socket/
plug(s). Do NOT push tools into the contacts.
4. Once a year (as a minimum), the charger should be electrically
inspected/tested by an appropriately qualified electrician in
accordance with the current legislation for the installation location.
If the equipment fails the inspection, isolate the equipment and
prevent its use until appropriate repairs/maintenance have been
completed. A record of the tests, results and any maintenance
must be kept and may be required to support warranty claims.
5. Do NOT allow charging cables to become contaminated with
water (or other substances).
NOTE: Rubber 'dust' caps that may be attached to cables are
only suitable for short term protection, or protection whilst stored
in an indoor environment. They are not designed to fully protect
against water ingress.
Commercial businesses with EV chargers should have a Site
Maintenance Plan that considers the type, frequency and intensity
of use of the equipment on site, and which schedules maintenance
as appropriate to keep the equipment in good working order.
EV charging equipment should be included in the electrical
element of the site maintenance plan and must be performed by
an appropriately qualified electrical engineer in accordance with
applicable regulations for the region of use.
A typical maintenance (inspection and testing) schedule is provided
on the next page. This schedule alternates on a quarterly basis
between a shorter and longer series of steps but the frequency of
which this work is performed must be determined in line with the
operator's Site Maintenance Plan. Failure to properly maintain the
charger will invalidate the warranty.
Suggested Inspection and Testing
A record or inspection, testing and maintenance must be kept and
may be required to support warranty claims.

sensor operate correctly.
• Clean the enclosure.

19
Advice provided above does not override any regulations that
may apply in the region of use. Quarterly Inspection and testing
(maintenance) is recommended where charger use is frequent
and/or intensive. Operators may consider increasing or reducing
elements of the maintenance frequency to a level that matches
the pattern of charger use but should, as a minimum, meet the
requirements of the current regulations.
