Connecting Equipment to the PowerTrust UPS (with 30A
Service Bypass Unit Only)
This section describes how to connect equipment to a UPS with a 30A Service Bypass Unit.
For information on how to connect equipment to a UPS with a 40A Service Bypass Unit,
refer to Appendix E, "40A Service Bypass Unit: Specifications and Procedures."
The UPS has four output receptacles. Typically, the SPU is connected to output receptacle
4 and one or more PDU(s) are connected to output receptacles 1, 2, and 3. If an SPU is not
being protected by the UPS, a PDU may also be connected to receptacle 4.
1. Position the expansion cabinet containing the PowerTrust UPS close to the AC input
source.
2. Make sure that the power switches of any equipment or PDU(s) being connected to the
UPS are in the OFF position.
3. Remove the cover mounted over the output receptacles by removing the two screws at
the top of the cover. See Figure 1-3,
4. Connect the line cord(s) from the PDU(s) to the IEC 320 C19 output receptacle(s).
5. Connect the SPU or PDU to the UPS:
• North American version—Plug the SPU or PDU line cord into the NEMA L6-30R
receptacle.
• Worldwide version—Hardwire the SPU or PDU line cord to the UPS. Refer to "Input

6-50P).
• Worldwide version—Hardwire a connection from the AC input source to the UPS.
Refer to "Input and Output Connections" earlier in this chapter for detailed
