NOTICE
NOTICE is used to address practices not related to physical injury. The safety alert symbol shall not be used with this type of safety message.
Failure to follow these instructions can result in equipment damage.

Please Note

Electrical equipment should only be installed, operated, serviced, and maintained by qualified personnel. No responsibility is assumed by Schneider Electric for any consequences arising out of the use of this material.

A qualified person is one who has skills and knowledge related to the construction, installation, and operation of electrical equipment and has received safety training to recognize and avoid the hazards involved.

Electromagnetic Compatibility

NOTICE
Risk of electromagnetic disturbance
This is a product Category C3 according to IEC 62040-2. This is a product for commercial and industrial applications in the second environment - installation restrictions or additional measures may be needed to prevent disturbances. The second environment includes all commercial, light industry, and industrial locations other than residential, commercial, and light industrial premises directly connected without intermediate transformer to a public low-voltage mains supply. The installation and cabling must follow the electromagnetic compatibility rules, e.g.:
  • the segregation of cables,
  • the use of shielded or special cables when relevant,
  • the use of grounded metallic cable tray and supports.
Failure to follow these instructions can result in equipment damage.

Safety Precautions

DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
Read all instructions in the installation manual before installing or working on this product.
Failure to follow these instructions will result in death or serious injury.
DANGER
hazard of electric shock, explosion, or arc flash
Do not install the product until all construction work has been completed and the installation room has been cleaned.
Failure to follow these instructions will result in death or serious injury.
DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
The product must be installed according to the specifications and requirements as defined by Schneider Electric. It concerns in particular the external and internal protections (upstream breakers, battery breakers, cabling, etc.) and environmental requirements. No responsibility is assumed by Schneider Electric if these requirements are not respected.
Failure to follow these instructions will result in death or serious injury.
DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
The UPS system must be installed according to local and national regulations. Install the UPS according to:
  • IEC 60364 (including 60364–4–41- protection against electric shock, 60364–4–42 - protection against thermal effect, and 60364–4–43 - protection against overcurrent), or
  • NEC NFPA 70, or
  • Canadian Electrical Code (C22.1, Part 1)
depending on which one of the standards apply in your local area.
Failure to follow these instructions will result in death or serious injury.
DANGER
hazard of electric shock, explosion, or arc flash
  • Install the product in a temperature controlled indoor environment free of conductive contaminants and humidity.
  • Install the product on a non-flammable, level and solid surface (e.g. concrete) that can support the weight of the system.
Failure to follow these instructions will result in death or serious injury.
DANGER
hazard of electric shock, explosion, or arc flash
The product is not designed for and must therefore not be installed in the following unusual operating environments:
  • Damaging fumes
  • Explosive mixtures of dust or gases, corrosive gases, or conductive or radiant heat from other sources
  • Moisture, abrasive dust, steam or in an excessively damp environment
  • Fungus, insects, vermin
  • Salt-laden air or contaminated cooling refrigerant
  • Pollution degree higher than 2 according to IEC 60664-1
  • Exposure to abnormal vibrations, shocks, and tilting
  • Exposure to direct sunlight, heat sources, or strong electromagnetic fields
Failure to follow these instructions will result in death or serious injury.
DANGER
Hazard of electric shock, explosion, or arc flash
Do not drill or cut holes for cables or conduits with the gland plates installed and do not drill or cut holes in close proximity to the UPS.
Failure to follow these instructions will result in death or serious injury.
WARNING
HAZARD OF ARC FLASH
Do not make mechanical changes to the product (including removal of cabinet parts or drilling/cutting of holes) that are not described in the installation manual.
Failure to follow these instructions can result in death, serious injury, or equipment damage.
NOTICE
risk of overheating
Respect the space requirements around the product and do not cover the ventilation openings when the product is in operation.
Failure to follow these instructions can result in equipment damage.

Electrical Safety

DANGER
hazard of electric shock, explosion, or arc flash
  • Electrical equipment must be installed, operated, serviced, and maintained only by qualified personnel.
  • Apply appropriate personal protective equipment (PPE) and follow safe electrical work practices.
  • Turn off all power supplying the UPS system before working on or inside the equipment.
  • Before working on the UPS system, check for hazardous voltage between all terminals including the protective earth.
  • The UPS system contains an internal energy source. Hazardous voltage can be present even when disconnected from the mains supply. Before installing or servicing the UPS system, ensure that the units are OFF and that mains and batteries are disconnected. Wait five minutes before opening the UPS to allow the capacitors to discharge.
  • The UPS system must be properly earthed/grounded and due to a high leakage current, the earthing/grounding conductor must be connected first.
Failure to follow these instructions will result in death or serious injury.

Distribution-Related Backfeed

The upstream disconnection switchgear must be suitable for disconnection purposes. Before working on the upstream supply, the MBB must be locked in the open position using the built-in lockout function.

When installing the parallel maintenance bypass panel, warning labels must be posted on the load side of all upstream disconnection devices. The labels must be supplied by the user, displaying the following text (or equivalent in a language which is acceptable in the country in which the UPS system is installed):
