Danger to life due to electric shock when live components or cables are touched
High voltages are present in the conductive components or cables of the product. Touching live parts and cables
results in death or lethal injuries due to electric shock.
• Do not touch non-insulated parts or cables.
• Disconnect the product from voltage sources and make sure it cannot be reconnected before working on the
device.
• After disconnection, wait 15 minutes until the capacitors have discharged.
• Observe all safety information on components associated with the product.
• Wear suitable personal protective equipment for all work on the product.
Danger to life due to electric shock in case of overvoltages and if surge protection is missing
Overvoltages (e. g. in the event of a flash of lightning) can be further conducted into the building and to other
connected devices in the same network via the network cables or other data cables if there is no surge protection.
Touching live parts and cables results in death or lethal injuries due to electric shock.
• Ensure that all devices in the same network and the battery are integrated into the existing surge protection.
• When laying the network cables or other data cables outdoors, it must be ensured that a suitable surge
protection device is provided at the transition point of the cable from the product or the battery outdoors to the
inside of a building.
Danger to life due to electric shock in case of overvoltages and unsuitable loads
Overvoltages of up to 1500 V can occur in the stand-alone grid and in the battery-backup grid. If the loads are not
suitable for these overvoltages or are not safe to operate, a voltage that poses a danger to life may be present on
accessible parts or cables. Touching live parts and cables results in death or lethal injuries due to electric shock.
• Only connect loads that have a CE, RCM or UL designation. These loads are suitable for overvoltages of up to
1500 V.
• Operate the loads only when they are technically faultless and in an operationally safe state.
• Check the loads regularly for visible damage.
Danger to life due to electric shock when operating a damaged product
Operating a damaged product can lead to hazardous situations since high voltages can be present on accessible
product parts. Touching live parts and cables results in death or lethal injuries due to electric shock.
• Only operate the product when it is in a flawless technical condition and safe to operate.
• Check the product regularly for visible damage.
• Make sure that all external safety equipment is freely accessible at all times.
• Make sure that all safety equipment is in good working order.
• Wear suitable personal protective equipment for all work on the product.
