Safety Information
Ensure that the connector conforms to the SAE J1772 standard and that
the EVSE provides AC current. Please note this adapter is designed
exclusively for AC charging and is NOT compatible with any DC charging
station. Attempting to use it with a DC charging station can result in a
fire, resulting in personal injury and/or property damage.
Regularly inspect both the adapter and charging/connector ports to
identify any accumulated dirt or debris. When dirt or debris enters the
connection ports, there is a risk of overheating which can be
safeguarded by promptly removing dirt or debris using a compressed air
dispenser and electric cleaner, such as Deoxit® or WD-40® Specialist
Electrical Contact Cleaner.
DO NOT continue use if you observe any damage to connector ports or
pins.
DO NOT insert foreign objects into the port as this can cause damage
and pose a safety hazard.
ALWAYS utilize a connector that is UL / ETL / SGS certified. This
certification guarantees that the connector conforms to rigorous safety
and quality standards.
