Operation
3.0 Scope
Operation describes Epsilon STS TM system characteristics of indicators and controls, startup and shutdown proce-
dures, safety checklists, modes and specifications and theory of operating the Epsilon STS TM system.
3.1 Preparation for Operation
Several items must be considered when preparing the Epsilon STS™ system for operation.
Configuration The STS cabinet and any auxiliary cabinets (such as PMM cabinets containing power
distribution panels, transformers, etc.) must be arranged in the required configuration
to insure that the interconnection cables are located in the correct adjacent cabinets.
Location The cabinets must be situated in a location that provides for proper air flow and heat
rejection.
Environment The room in which the Epsilon STS™ system is located must maintain environmental
conditions within recommended tolerances.
Electrical Connections All electrical connections must utilize the top or bottom conduit entries provided. See
section 2 for details for connections.
The following sections discuss in more detail these items.
3.2 Pre-Start Up Safety Check List
◗ Ensure all power and control wires have been properly connected and securely tightened. Recheck phase
rotation for both sources and proper grounding of the equipment.
◗
Check to see that the upstream and downstream protective devices are not tripped, and have been sized
properly for the STS and load requirements.
◗ Check that the input voltage is the same as indicated on the STS nameplate, located inside the door of the
Epsilon STS™ module.
◗
Verify that the air filters located inside the STS module door (400/600A units only) are properly installed and
free of dust, dirt, and debris. Make certain that nothing is blocking the air intake underneath and around the
front bottom of the STS module and that the air exhaust on the top of the STS module is free of all obstructions.
◗
Verify that all switches, CB1-5 in the STS are in the “off” (open) position.
◗ All panels and covers are replaced and secured back in place.
◗ Check to see that the cabinet is resting on its the lifting leveler and not on the 4 casters.
◗ Check that the load-circuit beakers (where applicable) are in the "OFF" position.
