Please pay special attention to the use of “Danger” sym ols throughout this manual indicating electrical or
other safety hazards. Following these safety instructions is extremely important to avoid possi le injury or
death.
This sym ol is used throughout this manual to indicate the presence of high voltages, representing a hazard for
electric shock, urn or explosion. Follow the instructions carefully to avoid serious or fatal injury.
Follow safe electrical work practices:
• Read, understand, and follow the instructions efore installing this product.
• Disconnect and lock-out all power supplying equipment efore working on or installing a WaveStar Static
Transfer Switch. Use a properly rated voltage sensing device to confirm power is OFF.
• Install equipment in an appropriate electrical environment per local regulations.
• PCBs are ESD sensitive equipment: Ground yourself, discharge any static charge and ensure that the
device is effectively grounded efore handling the unit.
Electrical equipment should e installed, operated, serviced, and maintained only y qualified personnel and in
accordance with all local safety codes. Power Distri ution, Inc. assumes no responsi ility for any
consequences arising out of the use of this manual. This document should not be viewed as sufficient by

This manual descri es installation and operation of the Eaton®PDI WaveStar®TFA Static Transfer Switch 250-
1200A 3-Pole. “TFA” stands for “True Front Access”. The TFA Static Transfer Switch (TFA STS) requires front
access only for installation, operation, service, and infrared scanning. The TFA STS is a three-pole, two-position
transfer device that transparently transfers, automatically or manually, an output load etween two 3-phase
input power sources.
22..11 BBaassiicc CChhaarraacctteerriissttiiccss
Purpose The purpose of a Static Transfer Switch (STS) is to keep power supplied to a downstream mission-
critical load y switching etween redundant power sources.
While a site UPS removes power anomalies originating etween the power station and the site, an STS
mitigates the effects of anomalies etween the Uninterrupti le Power Supply (UPS), utility power source, or
another source and the STS load. These anomalies include the following:
• Loss of an upstream utility or UPS source
• Out of specification power from a power source
• Faulty transformers in PDUs
• Circuit reaker nuisance tripping
Transfer Switch The TFA STS is a standalone transfer switch with two AC input sources and one AC output
load. The TFA STS transparently transfers the output load automatically from one power source to the other, if
the active source fails or goes out of specification, or manually y operator directive, for testing or
maintenance.
Static Transfer Switch Unlike electromechanical transfer switches, an STS has no moving parts. It uses
semiconductor technology, specifically silicon controlled rectifiers (SCRs), as power switching elements,
achieving faster transfers.
Sources The two input AC power sources should e independent power sources that are nominally of the
same voltage, phase rotation, and frequency. Inputs are usually from uninterrupti le power supplies (UPSs),
ut can e utility power sources, transformer outputs, or PDU outputs.
Output load The TFA STS has a single AC output that supplies redundant power to downstream loads.
3-pole The TFA STS switches a 3-phase AC load etween the two AC sources. The neutral wire is not
switched.
Primary and Secondary Systems A TFA STS can e integrated with a PDU on output in a primary system or
integrated with two PDUs on input in a secondary system. The TFA STS ca inet is line-and-match with Eaton
PowerHu 2 and PowerPak 2 PDUs.
NOTE The term PDI in this manual refers to products previous manufactured y Power
Distri ution, Inc. All service and support for these features are now supplied y Eaton.
