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 an AC branch circuit (AC mains). Connection should only be performed 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.
