Warnings

Receiving/moving

Do not tilt the PDU greater than 45° from its vertical axis. Never lay the PDU on its side.

Installation/Maintenance

Only a certified electrician can:

• Connect the PDU to its power source

• Connect a switch to the EPO interface on the PDU

• Install a customer-specified, hard-wired power cable

Only a certified electrician or an APC Field Service Engineer can perform maintenance of the PDU.

When you connect the PDU to its power source, you must install a circuit breaker to protect the PDU

against over-current. Determine the type of circuit breaker that you need to install:

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.
