3.4 Connecting Rack Equipment
NOTE: Circuit breakers on Vertiv™’s MPH2™ Rack PDU are opened at the factory. The open circuit
breakers help mitigate high inrush current when input power is first connected.
To mitigate in-rush currents:
Close the branch circuit breakers and connect each load one at a time.
– or –
For MPH2™ Rack PDU-C and MPH2™ Rack PDU-R models, turn the receptacle off before connecting the
load.
Verify that the equipment to be connected meets these requirements:
•
Input power requirements of each load do not exceed the MPH2™ Rack PDU receptacle
ratings.
•
Input power cords are fully-engaged.
•
Total equipment power consumption will not overload the MPH2™ Rack PDU.
To connect equipment to a MPH2™ Rack PDU:
1. Make sure that input power is installed in accordance with national and local electric codes.
2. Verify that all equipment is turned off.
3. If the MPH2™ Rack PDU will be monitored over a network, connect an Ethernet cable to the
Network port on the RPC2.
4. Route the equipment power cables to the MPH2™ Rack PDU, following proper procedures and
good practices, such as segregating power cables from control cables and adhering to bend
radius limits specified by the equipment manufacturer.
5. Verify that the branch circuit breakers on the MPH2™ Rack PDU are open.
6. Connect the equpiment input power cables to the MPH2™ Rack PDU.
NOTE: All C13 and C19 receptacles on an MPH2™ Rack PDU are locking receptacles. Special locking
power cords may be field-installed on the equipment and are available from Vertiv™. If non-locking
power cords are used, the power cords should be secured through other methods to prevent
unintended power interruption.
