Acceptance and service handover
For the installed TA200DU-175, Test trip indication, auxiliary contacts, reset mode and feeder shutdown against the approved motor-protection design.
Capture the observed behavior, settings, installed revision and fault status of TA200DU-175. Keep those findings with the plant asset record so a later service team can distinguish this exact code from a related option.
Where this component fits
Use TA200DU-175 in the intended system context: Provide motor overload and phase-loss protection as part of a coordinated contactor starter.
Document the equipment served by TA200DU-175, the normal load or signal, the site environment and the reason this component was selected. A replacement must preserve that function, not just fit the available space.
Interface and compatibility route
Before approving TA200DU-175, Set the dial from the actual motor full-load current and check contactor fit, upstream short-circuit device and reset philosophy.
Compare the mating equipment, terminals, wiring diagram, supply, firmware or accessory choices as applicable to TA200DU-175. Resolve every mismatch before a purchase order or installation work package is released.
