Installing the system component circuit breakers in the PDP

Learn more about installing the component circuit breakers. Circuit breakers are supplied with the device that you are installing.

DANGER

Use only the circuit breakers that were provided with the device that you are installing. Using an incorrectly rated circuit breaker may create a safety hazard.

Note: If the device you are installing is not provided by IBM, you must provide the properly sized circuit breakers.

Note: A few installed devices might require either the A or B side circuit breaker to control the device's power. If the device requires an A or B side circuit breaker, install the circuit breaker to match the location of the installed cable. For example, if the cable is at location A4, the circuit breaker must be installed in position A4.

Attention: Ensure that the circuit breaker is in the off position before you insert it into the circuit breaker panel.

Remove the bottom screw that holds the circuit breaker cover to the selected circuit breaker position on the A side of the PDP. Set the screw and cover aside.

Use the screws that are provided with the circuit breaker to attach the cover that you removed in step 1 to the circuit breaker.

Figure 2. Circuit breaker installation (circuit breaker position shown is for reference only)
With the circuit breaker in the off position, insert it into the PDP position that matches the cable connection. The Line circuit breaker terminal must be at the top position. The front cover must be placed against the PDP panel. If the front cover is not against the PDP panel, press on it until it is placed against the panel.
Install the screw that you removed in step 1 to fasten the cover to the PDP.
Place an EIA location and current rating label in the small square above the circuit breaker position. To place these labels, complete the following steps:
1. Select a label from the PDP label strip that matches the current rating of the circuit breaker that is installed, for example 30A.
2. Install the current label in the lower section of the small square.
3. Select a label from the PDP label strip that matches the EIA location of the device that is supported by the circuit breaker, for example 17.
4. Install the EIA label in the upper section of the small square.

Repeat steps 1 - 5 for the B side circuit breaker.
Determine whether any additional circuit breakers must be installed. To install more than one circuit breaker, repeat steps 1 through 6.
