1. Introduction
Tripp Lite’s S3MT-60K480V and S3MT-100K480V input isolation transformers provide 480V (Delta) to 208V (Wye) step-
down and Isolation protection to the connected UPS and its load. The S3MT-60K600V and S3MT-100K600V Input isolation
transformers provide 600V (Delta) to 208V (Wye) step-down and isolation protection to the connected UPS and its load.
The transformer has input isolation to mitigate utility line surges and spikes, while protecting the UPS. The transformer
includes a built in breaker at the transformer output side for protection. The ball-bearing fans maintain quiet operation (four
fans for 60K models, three large fans for 100K models). An overheat-sensing relay and switch combine with a warning light
to provide over-temperature warning and overheating protection. The UPS system’s small footprint and quiet acoustic profile
enable installations with minimal space and noise impact. All transformer models feature rugged stainless steel housings with
front panels similar to the S3M-Series 208V 3-Phase UPS line.

CAUTION! Risk of electrical shock! Hazardous live parts inside this unit are energized from the transformer even when
the breaker is turned off.
WARNING! The unit intended for installation in a controlled environment.
CAUTION! A transformer can present a risk of electric shock and high short circuit current. The following precaution should
be observed when working on the transformer:
• Remove watches, rings or other metal objects.
• Use tools with insulated handles.
To reduce the risk of electric shock, disconnect the transformer and UPS from the mains supply before performing
maintenance or service.
