Tip: When there are a large number of outlets, set the value to a lower
number so that you can avoid a long wait before all the outlets are
available again.
Setting the Inrush Guard Delay
This section applies to outlet-switching capable models only.
When electrical devices are turned on, they can initially draw a very large
current known as inrush current. Inrush current typically lasts for 20-40
milliseconds. The inrush guard delay feature prevents a circuit breaker
trip due to the combined inrush current of many devices turned on at the
same time. For example, if the inrush guard delay is set to 100
milliseconds and two or more outlets are turned on at the same time, the
PDU will sequentially turn the outlets on with a 100 millisecond delay
occurring between each one.
To set the inrush guard delay time:
1. Click the PDU folder.
Note: The folder is named "my PX" by default. The name can be
customized. See
Naming the PDU (on page 112).
2. Click Setup in the Settings section. The Pdu Setup dialog appears.
3. In the Inrush Guard Delay field, click the drop-down arrow and select
an option from the list. Valid range is from 100 milliseconds to 2
seconds.
Time units in the list are explained below:

ms: millisecond(s)
 s: second(s)
You can also type a value if the desired time is not listed. For
example, type "600 ms" for 600 milliseconds.
4. Click OK.
