1. Introduction

Tripp Lite's S3MT-20K480V and S3MT-30K480V Input isolation transformers provide 480V (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. Two ball-bearing fans maintain quiet operation. 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.

2. Important Safety Warnings

SAVE THESE INSTRUCTIONS

This manual contains important instructions for models S3MT-20K480V and S3MT-30K480V that should be followed during installation and maintenance of the transformer and UPS.

⚠️ 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.

Servicing of the 3-phase transformer and UPS should be performed by Tripp Lite certified personnel with knowledge of the 3-phase transformer and UPS and all required precautions.

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 a 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.

4. 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

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 thermal switch will activate and will open the output beaker 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.

6. Storage

Before storing the isolation transformer, ensure all connections have been disconnected and all breakers are turned OFF. Replace all input or output access covers to avoid damaging any contacts.

The transformer must be stored in a clean, secure environment with temperatures between 5^ F to 140^ F (-15°C to 60^ C) and relative humidity less than 90% (non-condensing).

Store the transformer in its original shipping container, if possible.

WARNING: The transformer(s) is/are very heavy. Before storing the transformer, make sure to take into account the floor loading (kg/m ^2 ) requirements listed in section 5. Specifications under “Physical Info” to store safely.
