Endurance Charger safety guidance

Always follow these precautions when installing or using an Endurance Charger Panel.

Charging-area safety

  • Install and use the charger indoors in a sheltered, well-ventilated location.
  • Keep the charging area clear.
  • Keep sparks, flames and other ignition sources away from batteries. Batteries can release explosive gases while charging.
  • Wear suitable personal protective equipment when installing the charging system and when handling or charging batteries.
  • Follow your organisation's working procedures and complete an appropriate risk assessment.
  • Only trained and instructed people should use the charging system.

Battery safety

  • Only charge compatible rechargeable 12 V lead-acid batteries with a capacity between 50 Ah and 150 Ah.
  • Do not charge a frozen or non-rechargeable battery.
  • Do not use the Li-ion or High charging modes for traffic signal batteries. Use Normal mode.
  • Battery acid is corrosive. If it comes into contact with skin, rinse the affected area immediately with water and follow your organisation's first-aid procedure.
  • Regularly inspect batteries, charging leads and connectors for damage.
  • Do not use a battery, lead, connector or charger that appears damaged.

Electrical safety

  • The charging panel must be installed by a licensed or certified electrician.
  • The incoming supply must be protected by a 16 A overcurrent device.
  • Mains connections must comply with applicable electrical regulations.
  • Do not use the system if the AC power cable is damaged.
  • Do not remove or open the charger casing. There are no user-serviceable parts inside, and opening the casing is dangerous and will void the warranty.
  • The charging system must receive an annual portable appliance test (PAT) by a certified professional.

Safe connection order

Connect the system in this order:

  1. Make sure the AC power supply is switched off.
  2. Connect the charger's Anderson connector to the battery connector.
  3. Switch on the AC power supply.

Disconnect the system in the reverse order:

  1. Switch off the AC power supply.
  2. Disconnect the Anderson connectors between the battery and charger.
Stop using the system immediately if:
  • all charger status LEDs begin flashing;
  • an electrical protection device trips;
  • you see sparks;
  • you notice an unusual smell;
  • a battery becomes unusually hot; or
  • a cable, connector, battery or enclosure is damaged.

Switch off the system, disconnect the equipment safely and contact Traffic Group Signals for advice. Do not try to open or repair the charger yourself.
