DANGER
Danger to life due to electric shock when live components are touched on opening the product
High voltages are present in the live parts and cables inside the product during operation. Touching live parts and
cables results in death or lethal injuries due to electric shock.
• Do not open the product.
WARNING
Danger to life due to electric shock from destruction of the measuring device due to
overvoltage
Overvoltage can damage a measuring device and result in voltage being present in the enclosure of the measuring
device. Touching the live enclosure of the measuring device results in death or lethal injuries due to electric shock.
• Only use measuring devices with a DC input voltage range of 1000 V or higher.
WARNING
Danger to life due to burns caused by electric arcs through short-circuit currents
Short-circuit currents in the battery can cause heat build-up and electric arcs. Heat build-up and electric arcs may
result in lethal injuries due to burns.
• Disconnect the battery from all voltages sources prior to performing any work on the battery.
• Remove watches, rings and other metal objects prior to carrying out any work on the battery.
• Use insulated tools and wear insulated gloves for all work on the battery.
• Do not place tools or metal parts on the battery.
WARNING
Danger to life due to fire or explosion when batteries are fully discharged
A fire may occur due to incorrect charging of fully discharged batteries. This can result in death or serious injury.
• Put the battery into operation no longer than six months after delivery.
• If the battery is not put into operation within six months, contact Service to request reconditioning of the battery-
storage system.
• Before commissioning the system, verify that the battery is not fully discharged.
• Do not commission the system if the battery is fully discharged.
• If the battery is fully discharged, contact Service.
