Important Safety Instructions
Warning
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.
