1GENERAL PRODUCT DESCRIPTION
EFAPOWER EV-QC24S charging station is able to charge all electric vehicles compliant with Combined Charging
System (CCS) standard.
Depending on the battery capacity, EFAPOWER EV-QC24S can charge
properly equipped electric vehicles from 0% to 80% in roughly 60
minutes.
The charging session stop automatically based on signals from the EV,
or it can be manually stopped by the user.
EFAPOWER EV-QC24S is user friendly and safe. After user
identification, it only requires coupling the charger’s output plug in the
EV. The charge session will then start automatically after all safety
checks have been accomplished.
EFAPOWER EV-QC24S has a means of measuring the output energy,
which can be used for information and monitoring purposes. It uses
remote IP communication via GPRS, ADSL, WIFI or any other internet
access method to communicate business management data and
technical data.
The Quick Charger’s power electronics unique design results in top
tier specifications for conductive DC fast charging, such as high power
output with an industry best power factor, THD and efficiency.
EFAPOWER EV-QC24S has a switching technology with high reliability and high efficiency.
The Quick Charger is highly recommended for EV fleet bases, service stations, EV service workshops and public
EV infrastructure for fast charging.
EFAPOWER EV-QC24S codification and parts are presented in Chapter 3.

5INSTALLATION
All instructions for installing the EFAPOWER EV-QC24S are described in this chapter.
5.1 ENVIRONMENTAL REQUIREMENTS
EFAPOWER EV-QC24S reliability is dependent upon compliance of environmental specifications. The design of
the environmental control system for your EFAPOWER EV-QC24S, 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
The installation of EFAPOWER EV-QC24S shall not be made closer than 6,1m (20 feet) of an outdoor
motor fuel dispensing device.
EFAPOWER EV-QC24S is in an IP54, IK10 (NEMA 3R) enclosure. This Unit is intended to work below 40ᵒC (104ᵒF)
ambient temperature.
Clearance around the unit
The air must circulate freely throughout the ventilation grids in order for the charger’s cooling system to be
effective. The ventilation areas on the sides must not be blocked, assuring that the Quick Charger cooling system
can be effective. Efacec recommends clearance of at least 1meter (40’’) in the front (HMI interface and output
cable) and 500mm (20’’) of clearance in the sides of the unit.
Input Power Cables
AC input cables must be copper with appropriate power rating.
EFAPOWER EV-QC24S was intended to be placed as showed in the Figure 4.
Figure 4 - EFAPOWER EV-QC24S placing orientation

E F A P O W E R EV- Q C 2 4 S - 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

Even though non-conductive dust does not influence the system’s operation, it may however, with excessive
accumulation, not allow proper cooling, thereby limiting the equipment’s thermal capabilities. Consequently,
dust accumulation must be avoided in order to guarantee a better thermal performance.
Conductive dust and acid vapors must be kept away from the Quick Charger.
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 protection
roof for the Unit. See example in Figure 5.
Figure 5 - EFAPOWER EV-QC24S with shelter
5.1.2 SITE VERIFICATION AND INSPECTION
✓Check if the installation of the Quick Charger is not planned to be made closer than 6,1m (20 feet) of an
outdoor motor fuel dispensing device;
✓Check if the access passages to the Quick Charger Station layout site are not blocked in order to allow its
transportation;
✓Check if Quick Charger Station layout site is compliant with the specified clearance around the cabinet.

5.2 SITE PREPARATION
Once the local conditions have been verified, it is time to prepare the site for the installation of the EFAPOWER
EV-QC24S.
5.2.1 UPSTREAM WIRING INFORMATION
Depending on the configuration of the EFAPOWER EV-QC24S, it may have different wiring schemes as
represented in the following three figures:
CE MARKED UNITS:
▪Three phase input connection for CE marked unit:
This installation requires dedicated 50A circuit breaker 3P C curve, which shall be physically located
according to the local electrical codes.The wiring shall be done as shown above and a triple shunt
(supplied with the unit) shall be placed across neutral terminal blocks, represented in orange (X1.4,
X1.5and X1.6).
ETL MARKED UNITS:
▪Three phase input connection for ETL marked unit:
This installation requires a dedicated 100A circuit breaker 3P C curve, which shall be physically located
according to the local electrical codes. The wiring shall be done as shown above and three shunts
(supplied with the unit) shall be placed across phases terminal blocks, represented in orange (X1.1 and
X1.6; X1.2 and X1.3; X1.4 and X1.5).

(supplied with the unit) shall be placed across phase terminal blocks, represented in orange (X1.1, X1.2,
and X1.3, and also across X1.4, X1.5, and X1.6).
NOTES
In areas with frequent thunder storms, Efacec recommends adding transient voltage surge
suppression (TVSS) at the service panel for all circuits.
It is necessary to install a residual-current device (RCD) in the upstream installation switchboard of the
EFAPOWER EV-QC24S to assure protection.

5.3.4.1 MOUNTING ON THE WALL
Each unit must be installed by using the mounting plate and 7 (seven) M8 screws. Length must comply with local
codes. While a concrete wall for installation is preferred, installation on a drywall will be acceptable if 4 anchors
(5/16’’ dia. (M8) lag screws) are in studs and if the remaining drywall anchors are heavy-duty.
Mounting steps:
1Attach the mounting plate to the wall (use the drilling layout template)
This figure represents the height that the mounting plate must be placed.
To facilitate the wall mounting, a drilling layout template in 1:1 scale is supplied with the unit and the
next steps should be followed:
1Place the drilling template according to the illustration below;
2Remove the adhesive on the upper corners;
3Mark the holes (There are 4 specific holes, marked with circles, for mounting in drywall that
should match with most stud center-to-center distances.)

IMPORTANT:
▪Always requires an upstream protection. Please refer to Chapter 5.2.1 Upstream
Wiring Information to see the appropriate protection depending on the unit
configuration.
▪Use copper conductors only
▪Before starting to work on the Quick Charger Station, connect the ground wire to the
ground terminals of the Quick Charger Station
▪In areas with frequent thunder storms, we advise to add transient voltage surge suppression
(TVSS) at the service panel for all circuits
5.3.4.3 POWER CABLES CONNECTIONS
The metallic structure of the rectifier system is connected to the protective ground connection, which should be
interconnected with the low voltage switchboard ground connection.
To assure this interconnection, X1 GROUND MUST BE CONNECTED (35mm2terminal block).
The protective earth cable must have a cross section of at least of 16 mm2 (#6AWG) or according to local codes.
6START-UP
6.1 VERIFICATION AND INSPECTION
