1 IMPORTANT SAFETY INSTRUCTIONS

SAVE THESE INSTRUCTIONS
This safety sheet contains important safety instructions. Read all safety, installation and operating
instructions before installing the Vertiv™ MPH2™ Rack Power Distribution Unit (PDU). Adhere to all
warnings on the unit and in this safety sheet. Follow all instructions.
The MPH2™ Rack PDU is designed for information technology equipment. The MPH2™ Rack
PDU is not intended for use with life support or other designated critical devices. If uncertain
about its intended application, consult your local dealer or Vertiv™ representative.
Maximum load must not exceed the rating shown on the MPH2™ Rack PDU nameplate.
The rated line voltage must not exceed 240 VAC for connection to AC power distribution
systems with an isolated or high-impedance ground.
Operate the MPH2™ Rack PDU in an indoor environment only in the appropriate ambient
temperature range, as follows:
32°F to 140°F (0°C to 60°C) for 32A or less input models.
32°F to 122°F (0°C to 50°C) for 40A and 48A input models without case ventilation.
32°F to 140°F (0°C to 60°C) for 40A and 48A input models with case ventilation.
Install the MPH2™ Rack PDU in a clean environment, free of conductive contaminants,
moisture, flammable liquids, combustible gases and corrosive substances.
The MPH2™ Rack PDU must be installed in a restricted-access location. A restricted-access
location is an area where access is possible only through the use of a tool or lock and key or
other means of security, and is controlled by the authority responsible for the location.
The MPH2™ Rack PDU has no user-serviceable parts. Under no circumstances attempt to gain
internal access due to the risk of electric shock or burn.
Refer any unexpected behavior or unusual fault conditions to your local dealer, Vertiv™
representative or Vertiv™ Applications Engineering.
Vertiv recommends powering only safety agency approved devices from the MPH2 Rack PDU.
For permanently connected rack PDUs (hard-wired versions), a readily accessible disconnect
device must be incorporated externally to the equipment.
For rack PDUs with attached input power-supply cords, the socket must be installed near the
equipment and must be easily accessible.
