  • Page 37: Maintenance

    Maintenance Introduction WARNING: Do not remove the covers from the UPS case. If you remove a cover from the UPS case you will be exposed to potentially lethal voltages. The UPS does not contain any user-serviceable parts, so the day-to-day maintenance requirements are minimal other than to ensure that the environment in which the UPS is installed is kept cool and dust free.
  • Page 38 5: Maintenance Battery disposal and recycling WARNING: Do not attempt to remove or replace the UPS battery yourself. If a battery is faulty ALWAYS seek assistance form Uninterruptible Power Supplies Ltd. or one of its local service agents. Batteries contain dangerous substances that can harm the environment if disposed of carelessly. If you have a faulty battery it should be checked and replaced by a trained Uninterruptible Power Supplies engineer who will dispose of any faulty batteries in accordance with any regulations set by local environmental waste disposal organisations.
