Safety and Compliance Information for Server, Storage, Power, Networking, and Rack Products

◦ For rack installations, do not exceed the maximum number of UPS products in any single
equipment rack.
◦ For rack installations, install the UPS only at the bottom of a rack.
• To reduce the risk of personal injury or damage to equipment when installing a Remote
Emergency Power Off (REPO) port:
◦ The REPO port must be wired by a licensed electrician.
◦ Verify that the main AC power disconnect device for the UPS is locked and/or tagged
in the OFF position before wiring the REPO port.
◦ In North America, the REPO circuit must comply with the NEC (NFPA 70, Article 725)
for a Class 2 circuit. In other geographical regions or countries, the REPO port wiring
must comply with the national and local standards in the area in which the product is
installed.
• To reduce the risk of personal injury from electric shock or damage to equipment when installing
or servicing batteries:
◦ Make sure that only trained service personnel handle or connect the batteries.
◦ Remove watches, rings, or other metal objects prior to working with the equipment.
◦ Use tools with insulated handles.
◦ On products with remote external batteries, do not attempt to replace batteries unless all
battery circuit breakers are in the OFF (down) position. These are hazardous voltage
batteries.
• This product may contain sealed lead-acid batteries. To reduce the risk of fire or chemical
burns:
◦ Do not attempt to recharge batteries after they have been removed from the equipment.
◦ Do not disassemble, crush, or puncture the batteries.
◦ Do not short the external contacts of the batteries.
◦ Do not immerse the batteries in water.
◦ Do not expose the batteries to temperatures higher than 60°C or dispose of in fire.
◦ Use only the HP spare battery designated for this equipment.
Power distribution units (PDUs)
To reduce the risk of electric shock and/or equipment damage when installing or servicing PDUs:
• The installation and routine maintenance and service of PDUs must be performed by trained
service technicians who are knowledgeable about the procedures, precautions, and hazards
associated with AC power products.
• Hardwired PDUs require a direct connection to a dedicated AC branch circuit (AC mains).
Connection should only be performed by a licensed electrician in accordance with National
Electrical Code (NFPA70 Article 310) in North America, or in other regions or countries, in
accordance with the equivalent local and national wiring regulations.
• A reliable grounded (earthed) connection should be checked before connecting PDUs.
• Use a Lockout/Tagout procedure to isolate hardwired PDUs from AC power before servicing
or replacing the product.
