SAFETY INSTRUCTIONS
IMPORTANT!
Read carefully all documentation before handling the equipment and pay special attention to safety
recommendations to maximize the performance of this product and ensure its safe use and installation.
The installer must follow the instructions provided in this manual, as well as the good electrical practices
and identify all warnings and recommendations before starting up and operating the electric vehicles
charger.
WARNING
FIRST CONSIDERATIONS
The operations detailed in this manual can only be performed by qualified personnel.
The condition of qualified personnel referred to in this manual shall be at least the condition that meets
the standards, regulations and safety laws applied to the installation and operation of this equipment.
Read and retain the Installation Manual for future reference.
Before assembling the charger, read all instructions, caution signs and other sections of this manual.
Failure to follow these warnings can result in severe electrical shock or death. Pay attention at all times
to prevent possible accidents.
Make sure that all safety regulations in force at the place where the charger is installed regarding
both Medium Voltage and Low Voltage operations are complied with. Otherwise, you may get an
electric shock.
The electric vehicle charging system may cause an ELECTRICAL DISCHARGE if the warnings
indicated in this manual are not followed.
Make sure the charger is completely disconnected from the power supply and grounded before
handling or servicing. Otherwise, there is a risk of electric shock. To avoid electrical hazards,
disconnect the input supply, ground the equipment, remove control voltages before performing any tasks,
and ensure that busbars are completely discharged. Warning and safety labels must be properly affixed
to terminals, cabinets and control panels in accordance with local regulations.
When working on electrical installations, always remember to apply the FIVE GOLDEN RULES:
1. Visible shutdown of all live sources.
2. Mechanical locking of all cutting elements.
3. Verify the absence of voltage by using the appropriate tools for the voltage of the installation.
4. Ground and short-circuit all possible voltage sources.
5. Delimit and mark the work area.
Do not modify the equipment. If you fail to do so, Power Electronics will not assume any liability, and
the product warranty will be voided.

SAFETY INSTRUCTIONS
WARNING
The housing must be properly closed, otherwise it may not adequately protect people or
property from any abnormal situation inside the equipment.
The output airflow can reach high temperatures that could harm people exposed to it.
Electric shock danger. The steps to isolate the equipment must be carefully followed before performing
any task or opening any cover of the equipment. Avoid inappropriate actions that may cause electric
shock.
Always wear the appropriate personal protective equipment (PPE) for each task. and work in
electrical areas with dry hands. Otherwise, you may get an electric shock.
Do not subject cables to abrasion, excessive stress, heavy loads or pinching. Otherwise, you may
get an electric shock.
Do not supply power to a damaged charger or charger with missing parts, even if the installation
is complete. Otherwise, you may get an electric shock.
In the event that the charger stops due to a loss of power, do not do any work on it. The auto-restart
function may be enabled and you may receive an electric shock.
During any maintenance task on the equipment, please make sure that there will be no
electric vehicle connected charging.
USE
Do not use this equipment for purposes other than the electric vehicle charging with the modes
provided for this product and defined in this manual.
Do not disconnect or connect any terminals while the equipment is running. Otherwise, you may
get an electric shock and the equipment may be damaged.
Do not use this product if its enclosure or electric vehicle connector(s) (on both the charger and
vehicle sides) or insulation cable are broken, cracked or otherwise damaged. Otherwise, you may
get an electric shock
CONNECTION TO EARTH
Prevention of electric shock:
•The charger chassis must be properly grounded to prevent a possible electrical shock if a leakage
current flows through the enclosure. Disconnect all power supplies before proceeding with
maintenance operations inside the equipment.
•Only connect the grounding device to the charger's grounding plate. Do not use the enclosure or
chassis screws for grounding.
The protective earth wire must be connected first and last disconnected
