The STS2/PDU standard model is provided with a circuit breaker for connecting to the load or a
remote distribution cabinet. Other distribution configurations are available.
The three main types of distributions available for the STS2/PDU are:
• Output Breaker
• Inline Panelboards—two panelboards (84 poles) on 250A units and four panelboards (168 poles)
on 400-800A units. Square D
bolt-in or plug-in breakers.
• Square D I-Line
to 250A. Additionally, 300A to 400A breakers are available on 800A units.
For other optional distribution methods, contact your local Liebert representative or call
1-800-LIEBERT.
The STS2/PDU distribution may be mounted on either the right or left side at the customer's option.
Location of output conduit connections is affected by the location of the output cabinet. See
Figures 8, 9, 12, 13, 16 and 17 for wiring a right-side distribution configuration and
Figures 10, 11, 14, 15, 18 and 19 for wiring a left-side distribution configuration. See Figures 23
through 44 for wiring.
See Table 7 for wiring the various output options.
