1GENERAL PRODUCT DESCRIPTION
EFAPOWER EV-Home Charger (HC) station is able to charge all electric vehicles compliant with AC charging
system standards.
The battery charging cycle finishes by itself or can be interrupted by user command.
EFAPOWER EV-HC consists on a Charging Station with one output.
Are available the following AC outputs: 3,7kVA; 7,4kVA; 11kVA and
22kVA.
EFAPOWER EV-HC station is user friendly and safe. Different models
are available, with power plug or socket. When equipped with a
socket, the power cord plug is coupled into it in the charger bay.
There is a locking mechanism on the socket that prevents the user
from disconnecting the power cord during the charging process,
without first interrupt the charging process on the system or on the
vehicle. The charger has a color warning light which shows its own
operation status.
EFAPOWER EV-Home Charger station codification and configurations are presented in chapter 3.

4IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS
This manual contains important instructions that must be followed during installation of the EFAPOWER EV-HC
Station.
Grounding instructions
The EFAPOWER EV-HC Station must be connected to a grounded, metal, permanent wiring system; or an
equipment-grounding conductor is to be run with circuit conductors and connected to the equipment grounding
terminal or lead on the Electric Vehicle Supply Equipment (EVSE). Connections to the EVSE shall comply with all
local codes and ordinances.
Safety and compliance
This document provides instructions to install the EFAPOWER EV-HC Station and should not be used for any other

5INSTALLATION
All matters for installing the EFAPOWER EV-HC are described in this chapter.
5.1 ENVIRONMENTAL REQUIREMENTS
EFAPOWER EV-HC Station reliability is dependent upon compliance of environmental specifications. The design
of the environmental control system for your EFAPOWER EV-HC Station, in case of extreme environmental
conditions, must ensure that the Unit can operate reliably while remaining within the range of its operating
specifications.
5.1.1 LOCAL CONDITIONS
EFAPOWER EV-HC Station has a protection degree of IP54. This Unit is intended to work below 50ᵒC ambient
temperature.
Clearance around the unit
There should be enough space to operate the unit in the front and both sides. For EV-HC 11 / 22 please ensure
also clearance in the bottom to access to the RCD.
Input Power Cables
AC input cables must be copper with appropriate power rating.
EFAPOWER EV-HC is intended to be placed on the wall, as showed in Figure 5.
Figure 5 - EFAPOWER EV-HC Station –placing

E F A P O W E R EV- H C - I N S T A L L A T I O N A N D U S E R M A N U A L
8 | 28
On locations with harsh weather conditions (high temperatures, heavy dust, snow and/or very low temperatures)
it’s recommended to provide additional protection, either inside a building or a shelter, or providing a roof
protection for the Unit. See example in Figure 6.
Figure 6 - EFAPOWER EV-HC with roof protection
5.1.2 SITE VERIFICATION AND INSPECTION
Check if Home Charger Station layout site is compliant with the specified clearance around the box;

E F A P O W E R EV- H C - I N S T A L L A T I O N A N D U S E R M A N U A L

5.2 SITE PREPARATION
Once the local conditions are verified is time to set up the site in order to be ready for the installation of the
EFAPOWER EV-HC Station.
5.2.1 UPSTREAM WIRING INFORMATION
The power feeding of the EFAPOWER EV-HC with origin on the LVDB (low voltage distribution board) must be
done with dedicated wiring (line(s), neutral and earth conductors only used to supply the equipment) and
protected by a circuit breaker and a voltage suppressor, please refer Figure 7 and Figure 8.
Depending on the output of the Unit, we can have several scenarios for the circuit breaker to be installed in the
distribution board for each Unit. The appropriate circuit breaker is represented in Table 3.
NOTES
Unless it’s required by local code it’s not necessary to install a residual-current device (RCD) for
EFAPOWER EV-HC Station as it is already installed inside the unit.

5.2.4 SITE VERIFICATION AND INSPECTION
Check if Home Charger has the appropriate upstream protection depending on the configuration of it
Verify if the neutral is of type TT or TN. Only these two regimes guarantee a good and correct
functioning of the EFAPOWER EV-HC residual current device
Verify the earth circuit resistance: it should be according to IEC 60364/GB 16895.3, and other applicable
standards. In either case it must be under 150 Ω
Verify if the main distribution board has conditions to support one more circuit with the characteristics
required depending on the model
Execute and test the installation according to IEC 60364 standard or local regulations for CE marked
units and according to GB 16895.3, GB/T 16895.10, GB16895.5 standards or local regulations for GB
marked units
A test document will be issued by the installer responsible as a guarantee to the user that the
Homecharger was properly installed and ready to supply energy to charge the EV battery

5.3.4 PLACING
5.3.4.1 FIXING ON THE WALL
Each unit must be installed by using 3 (three) screw anchors, M4 –length must comply with local codes.
The fixation of the EV-HC should assure that no part of it is under 0,8m or above 1,5m from ground thus
permitting a comfortable handling of the equipment and charging cable.
Mounting steps:
1. Unscrew the lid
All 4 screws must be untighten to take off the lid.
2. Disconnect the lid
The lid shall not be hanging on the wires!
a. Unplug the earth cable on it (faston terminal)
b. Unplug the flat cable on the board (X14)
c. Unplug the card reader cable on the board (X6) –if applicable
3. Fix the Unit to the wall (use the drilling layout template)
In the following figures some details are shown regarding the drilling layout for both boxes.
Only 3(three) points are needed to fix each Unit on the wall (marked with a red circle) with M4 bolt.
To make easier the wall mounting, a drilling layout template, 1:1 scale, is supplied with the unit.
Additional 2(two) screws and matching anchors are need if the EV-HC has charging cable (for cable
holder).

A. Converter connected to a pre-installation outside EV-HC
If it’s not suitable the USB-RS485 converter connected directly to the EV-HC, due to distance constraints,
alternative pre-installation it’s allowed (Figure 15):
A shielded communication cable of at least 3 conductors can be connected to the EV-HC (through X2)
and end into a 3 pin panel outlet connector near a suitable place to connect the PC.
ATTENTION: This panel connector shall not be standard in order to prevent anyone to connect an
everyday use cable to the charger. USB, RJ45 adapter should not be used. This connector can also be
somehow locked to prevent inadequate use.
The mate male connector shall be assembled to the USB-RS485 FTDI converter, refer Table 6.
The panel outlet connector can now be installed in a suitable place, without length constrains, where the PC is
located. The USB-RS485 converter will link between the panel connector and the PC providing full access to the
Home Charger.

B. Converter directly connected to EV-HC
In this case the converter is directly connected to the X2 terminal of EV-HC, as represented in Figure 16.
The USB connection point can now be installed in a fixed location where the PC is located, providing full access
to the Home Charger.
A Network of EV-HCs connected to a Local PC
This scenario is a development of the previous. In this situation, all the chargers are connected together through
the X2 connector in Unit, and each charger is equipped with a RFID card reader and/or meter.
If the charger isn’t equipped with an Energy Meter, the energy field on the transactions will be zero.
The transactions can be saved in an excel file ant therefore reports of charge associated to a specific RFID card
can be generated.
ATTENTION: There is a Maximum limit of the number of the chargers that can be connected this way: 127
chargers in the network.
A USB-RS485 converter is used to connect all the chargers to a Local PC, refer Table 6.
The USB converter is connected between the Local PC and the first/closest charger (through X2). The pre-
installation presented above can be implemented.
Thereafter each charger is connected through the same X2 terminal till the last. A shielded communication cable
of at least 3 conductors shall be used, as represented in the following figure.
