Introduction

Tripp Lite’s S3MT-60K480V and S3MT-100K480V input isolation transformers provide 480V (Delta) to 208V (Wye) stepdown 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 PS 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.

The transformer is extremely heavy. Caution should be taken in moving and positioning equipment. The instructions contained within this manual are important and should be closely followed at all times during installation and follow-up maintenance of the 3-phase transformer and UPS.

CAUTION!
The transformer has a dangerous level of heat. If the transformer’s front- panel red LED indicator is on, the unit’s outlets may have a dangerous level of heat.
All servicing on this equipment must be carried out by Tripp Lite-certified service personnel. Before conducting any maintenance, repair, or shipment, first, ensure everything is turned off completely and disconnected.

Special Symbols – The following symbols are used on the transformer to warn you of precautions:
** RISK OF ELECTRIC SHOCK – Observe the warning that risk of electric shock is present.
CAUTION** – REFER TO THE OWNER’S MANUAL for information regarding important operating and maintenance instructions.
SAFE GROUNDING TERMINAL – Indicates THE primary safe ground.

3.7 Transformer-to-UPS Connection Line Diagram
Connections are shown below for the cabinet with a built-in input isolator transformer, breakers and the red over-temperature LED.

3.8 Multiple Transformer Connections

WARNING: The transformer output neutral is not bonded to chassis ground. Please provide a means to connect the transformer chassis ground to the transformer output neutral.
Note: The transformer chassis ground must be connected to earth ground.
IMPORTANT: You may view and/or download this manual from the tripplite.com website to view the cable connections in colors.

3.8.1 Connections for S3MT-60K480V/S3MT-60K600V to S3M50K or S3M60K UPS
Transfomer input is Delta 3-Wire (3Ph + Ground) And transformer output is Wye 4-Wire (3Ph + N + Ground).

3.8.2 Connections for S3MT-100K480V/S3MT-100K600V to S3M80K or S3M100K UPS
Transfomer input is Delta 3-Wire (3Ph + Ground) And transformer output is Wye 4-Wire (3Ph + N + Ground).

Operation

WARNING: It is not advised to connect two UPS in parallel when using individual transformers for each UPS.

4.1 Over-Temperature Protection
4.1.1 Over-Temperature Red Warning LED Light
The transformer includes a warning LED light on the top portion of the front panel. The light turns ON when the transformer reaches a temperature of 160°C ±5°C, i.e. a range of 155°C to 165°C (311°F to 329°F). The light turns OFF when the transformer cools to a temperature of 125°C ±5°C, i.e. a range of 120°C to 130°C (248°F to 266°F).
4.1.2 Over-Temperature Protection Relay and Thermal Switch
The transformer includes an over-temperature protection relay and thermal switch to protect the transformer from overheating. At temperatures of 160°C ±5°C, i.e. a range of 155°C to 165°C (311°F to 329°F), an over-temperature protection relay and the thermal switch will activate and will open the output breaker of the transformer. Once the transformer temperature has cooled down and the warning LED light has turned OFF, you may manually re-activate (close) the output breaker to restart normal operation.
