Warnings
Installation/Maintenance
Only a certified electrician can:
• Connect the InfraStruXure PDU to Mains
• Connect a switch to the EPO interface on the InfraStruXure PDU
Only a certified electrician or an APC Field Service Engineer can:
• Connect the InfraStruXure PDU to the Symmetra PX UPS
• Perform maintenance of the InfraStruXure PDU
When you connect the InfraStruXure PDU to Mains, you must install a 100A (minimum) circuit
breaker to protect the InfraStruXure PDU against over-current. This circuit breaker must have a CE
Mark and a certification mark by a certified body such as VDE, SEV, BSE, KEMA, or Semko.
Maintenance performed while the PDU is receiving input power
APC does not recommend that you perform maintenance of the PDU while it is receiving input
power. However, due to the critical nature of data center loads, this may occur. If you must perform
maintenance while the PDU is receiving input power, observe the following precautions to reduce the
risk of electric shock:
1. Never work alone.
2. Perform the maintenance only if you are a certified electrician who is trained in the hazards of
live electrical installation.
3. Know the procedure for disconnecting electricity to the PDU and the data center in case of an
emergency.
4. Wear appropriate personal protective equipment.
5. Use double-insulated tools.
6. Always follow local and site regulations when working on the PDU.
