injury or death.
Liebert MPH units contain no user-serviceable parts. For troubleshooting, contact Emerson
Network Power Applications Engineering or your local Emerson representative. Do not

NOTICE
Risk of improper installation. Can cause equipment damage.
Connecting your Liebert MPH and rack equipment to a power supply with an incorrect rating
in voltage, amperes or phase may damage the connected equipment and your Liebert MPH.
If you have questions about the power supply connections, contact Emerson Network Power
Applications Engineering or your local Emerson representative.
The user/installer must ensure that the ratings of the electric circuit of each connected
application and component meets the specified rating at each branch. The maximum load per
branch is 20 amps.
NOTICE
Risk of improper installation. Can cause equipment damage.
Shut down and unplug all equipment in your rack enclosure before beginning to connect the
equipment to a Liebert MPH.
When connecting the rack equipment to the Liebert MPH's receptacles, arrange cables and
connections to avoid tangling and crisscrossing the power cables. Keeping cables neatly
arranged will ease troubleshooting equipment problems.
For power management purposes, record the receptacle where each piece of equipment is
connected. Receptacles on the Liebert MPH have a numerical designation. A Liebert MPH
with more than one circuit has the outlets named with numbers and are grouped by branch
with a number referring to the proper circuit breaker.
NOTE
The Liebert MPH ships with its branch circuit breakers in the Open/Off position. To power up
the rack equipment:
1. Plug rack equipment into the Liebert MPH receptacles.
2. Apply power to the Liebert MPH strip.
3. Close one branch circuit breaker at a time to power up connected rack equipment.
