Safety Notice

Essential precautions for selecting, installing, commissioning, operating, transporting, and maintaining JKESS battery and energy storage products.

Qualified personnel only

Battery management systems, battery enclosure kits, high-voltage control equipment, and commercial energy storage systems can expose people and property to electric shock, arc flash, fire, explosion, chemical, thermal, mechanical, and stored-energy hazards.

Installation, wiring, configuration, commissioning, inspection, repair, and maintenance must be carried out by trained and qualified personnel using appropriate tools, test equipment, personal protective equipment, and safe work procedures.

Follow applicable requirements

  • Follow all applicable electrical, building, fire, grid-connection, transport, environmental, and occupational safety rules.
  • Follow the product manual, wiring diagram, specification sheet, labels, warnings, and written JKESS instructions.
  • Use correctly rated fuses, breakers, disconnects, contactors, insulation monitoring, grounding, enclosures, ventilation, fire protection, and emergency isolation devices.
  • Confirm that the product is approved and suitable for the intended country, site, environment, and application before installation.

Battery cells and system compatibility

Battery cells are not included with JKESS battery enclosure kits unless expressly stated. The installer is responsible for selecting compatible cells and verifying chemistry, voltage, capacity, dimensions, compression, insulation, busbars, current limits, temperature sensing, and BMS settings.

Never mix incompatible cell types, chemistries, capacities, states of charge, ages, or conditions. Do not energize a system until polarity, torque, insulation, clearances, communications, protection settings, and emergency controls have been verified.

High-voltage precautions

  • Treat all conductors and components as energized until a qualified person has isolated, locked out, tested, and verified a safe state.
  • Observe required discharge times and verify residual voltage before touching or servicing equipment.
  • Use insulated tools and correctly rated meters and protective equipment.
  • Do not bypass interlocks, contactors, fuses, insulation monitoring, alarms, or protective functions.

Operating environment

Do not operate products outside their specified temperature, humidity, altitude, ingress-protection, ventilation, current, voltage, and mechanical limits. Keep products away from water, conductive dust, corrosive substances, heat sources, ignition sources, unauthorized persons, and physical damage unless the product is expressly rated for those conditions.

Abnormal conditions and emergencies

Stop operation and isolate the system if there is smoke, fire, unusual heat, swelling, odor, leakage, abnormal noise, insulation alarm, repeated protection trip, damaged wiring, water ingress, impact, or unexplained voltage or temperature behavior.

Follow the site emergency plan and contact qualified emergency responders where required. Do not touch, move, recharge, reuse, or transport damaged battery equipment without professional assessment.

Transport, storage, and disposal

Use compliant packaging, labels, documentation, terminals protection, state-of-charge controls, and authorized carriers where transport rules apply. Store equipment in the specified environment and protect it against short circuit, impact, moisture, and unauthorized access.

Dispose of batteries, electronics, and packaging through authorized recycling or waste channels. Do not place battery cells or energized equipment in general household waste.

Responsibility

JKESS product information does not replace professional engineering, site-specific risk assessment, applicable codes, or installer responsibilities. Contact zhou@jkess.com before use if any specification, compatibility, or safety requirement is unclear.

Questions about this policy or an order should be sent to zhou@jkess.com.
