Safety Provisions

Before installing, operating, or maintaining this equipment, read and understand this bulletin, all steps described herein, and all schematics and electrical diagrams.

Electrical equipment should be installed and serviced only by qualified electrical personnel in accordance with national and local electrical codes.

DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH Apply appropriate personal protective equipment (PPE) and follow safe electrical work practices. See NFPA 70E, CSA Z462, or NOM-029-STPS-2011. This equipment must only be installed and serviced by qualified, trained, and certified electrical personnel. Only qualified electrical personnel familiar with medium voltage circuits should perform the instructions in this bulletin. Personnel must understand the hazards involved in working with or near medium voltage equipment. Qualified electrical personnel must perform work in accordance with national and local electric codes. Perform such work only after reading and understanding all of the instructions in this bulletin. Before performing assembly, visual inspections, testing, or maintenance on the equipment, disconnect all sources of electric power. Assume that all circuits are live until they have been completely de-energized, tested, grounded, and tagged. Pay particular attention to the design of the power system. Consider all sources of power, including the possibility of back-feeding. Never disconnect the main trip source of energized equipment. Always use a properly rated voltage sensing device to confirm power is off. Before making any electrical connections, ensure that all leads to be connected are de-energized and proper safety grounds are applied. Metal enclosed switchgear has interlocks designed to minimize hazards to the user. The user of this device is responsible for recognizing the potential hazards, for wearing personal protective equipment, and for taking adequate safety precautions. Do not make any adjustments to the equipment or operate the system with safety features removed. Contact your local Schneider Electric representative for additional instructions if the device does not function as described in this manual. Handle this equipment carefully and install, operate, and maintain it correctly in order for it to function properly. Ensure that the ground circuit is correctly assembled. Preventive maintenance operations must be carried out regularly. Follow regular inspection, checking the gas pressure and condition of the external elements, and carry out the usual cleaning task. Refer to Maintenance Program. Carefully inspect your work area and remove any tools and objects left inside the equipment. Replace all devices, doors, and covers before turning on the power to this equipment. All instructions in this manual are written with the assumption that the customer has taken these measures before performing installation, operation, maintenance, or testing. Failure to follow these instructions will result in death or serious injury.

DANGER
INSULATING GAS LEAKAGE Do not drill into or open the pressurized container. Failure to follow these instructions will result in death or serious injury.

DANGER
moving parts in mechanical drive See important safety information on page 7. Release the circuit breaker energy storage device by ON-OFF-ON operation of the circuit breaker. Switch the appropriate grounding to the grounded position. Do not remove mechanism during maintenance work. Failure to follow these instructions will result in death or serious injury.

DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH Do not operate or install any equipment that appears damaged. Failure to follow these instructions will result in death or serious injury.

WARNING
Potential compromise of system availability, integrity, and confidentiality Change default passwords to minimize instances of unauthorized access to device settings and information. Disable unused ports/services and default accounts, where possible, to minimize pathways for malicious attacks. Place networked devices behind multiple layers of cyber defenses (such as fire walls, network segmentation, and network intrusion detection and protection). Use cyber security best practices (for example, least privilege and separation of duties) to minimize chances of unauthorized exposure, loss, modification of data and logs, interruption of services, or unintended operation. Failure to follow these instructions can result in death, serious injury, or equipment damage.
