This safety data sheet addresses the two electrical hazards that may develop when PRC batteries are connected to form battery systems, used as part of a UPS or other emergency power equipment.
  1. Electrical Shock Hazard PRC batteries are commonly connected in series-parallel configurations in order to form battery systems having sufficient ampere-hour capacities and appropriate nominal voltages, to be used as part of a UPS or other emergency power equipment. The high voltages attained in battery systems can present a serious electrical shock hazard. This hazard will be always present, even when the battery system is off-line.
  2. Short Circuit Hazard Due to the high power densities and very low internal impedances of the PRC series batteries, extremely high levels of short circuit current (of the order of several thousand amperes) can develop in a battery circuit. This potential hazard is multiplied when the battery system consists of two or more parallel strings. Molten lead can splatter from the battery terminals when subjected to short circuit currents resulting from an incorrect connection. Take extreme care to connect only those points indicated on the wiring diagram to avoid a short circuit.

Safety precautions to take when working on battery systems

The following safety precautions Must be adopted when working with any battery system:

  1. Only Qualified Personnel, trained in proper electrical safety procedures, should be allowed to work with battery systems.
  2. All installation, maintenance and repair instructions and diagrams must be reviewed prior to working with the battery systems.
  3. Insulated tools Must be used when working on batteries. Avoid resting tools or loose cables on battery tops. Make sure at all times that cables are properly secured Before connections are made. Cable terminations are to be made Only after it has been determined that such a termination will not create a short circuit.
  4. Metallic objects such as watches and jewelry Must be removed prior to working on battery systems.
  5. Always wear safety goggles and gloves and use insulating mats to stand on when working on battery cabinets.
  6. Exercise extreme care to insure that No part of the battery cabinet is touched with bare skin while working on battery terminals, as this could result in an electrical shock.
  7. All applicable local and industry codes, such as the N.E.C., Must be implemented when installing battery systems.
