SAFETY INSTRUCTIONS
IMPORTANT!
Read carefully all documentation before manipulating the equipment and pay special attention to safety
recommendations to maximize the performance of this product and to ensure its safe use and installation.
It is the installer’s responsibility to follow the instructions provided on this manual, to follow good electrical
practices and to identify all mentioned warnings and recommendations before starting up and operating
the inverter.
WARNING
FIRST CONSIDERATIONS
The operations detailed in this manual may only be carried out by qualified personnel.
Qualified personnel referred to in this manual shall be applied to those who satisfy all safety standards,
regulations and laws applicable to the installation and operation of this equipment.
Read and keep the Hardware and Installation Manual for future reference.
Read all instructions and cautionary markings before installing the charger. Failure to follow these
warnings can result in serious electrical shock or even death. Pay attention at all times to prevent possible
accidents.
Ensure compliance with all safety regulations in force at the place where the charger is installed
in relation to both Medium and Low Voltage operations. Otherwise, you could get an electric shock.
The electric vehicle charging system is in danger of ELECTRICAL DISCHARGE if the warnings in
this manual are not followed. Make sure the charger is completely isolated and de-energized
before handling or servicing. 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 modified, Power Electronics will not assume any liability, and the
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 the task and work in electrical
areas with dry hands. Otherwise, you could get an electric shock.
Do not subject the cables to abrasions, excessive stress, heavy loads or pinching. Otherwise, you
could get an electric shock.
Do not supply power to a damaged charger or to a charger with missing parts, even if the
installation is complete. Otherwise, you could get an electric shock.
If the charger stops due to a loss of power, do not carry out any work on it. The automatic restart
function may be enabled, and you could get an electric shock.
During any maintenance work on the equipment, there will be no electric vehicle
connected and charging.
USE
Do not use this equipment for purposes other than the electric vehicle charging modes provided for
in this product and defined in this manual.
Do not disconnect nor connect any terminal while the equipment is working. Otherwise, you could
get an electric shock and cause damage to the equipment.
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
GROUND CONNECTION
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 disconnected last.
