If the startup of the UPS is critical to maintaining your schedule, please call the MGE toll free telephone number at 1-800-438-7373 for assistance. Final installation and start-up should be completed by a qualified MGE Field Service Engineer.
Epilson STS Step 1 Unpacking Once the Epsilon STS UPS System has been inspected and received from the shipping courier, the unit should be moved with the use of a fork lift or pallet jack to a position as close to the final installation location as possible. Prior to any installation, the following items should be observed upon receipt of the Epsilon STSTM 10-30 kVA UPS.
Epilson STS Step 2 Connection of Utility Power Inputs Connect Input Power from Two Sources The Epsilon STS™ systems provides for either top or bottom cable entry. Connections are to be made with 75°C copper wire cables and using the lugs supplied with the STS unit.

Scope Introduction is a general description of system characteristics of Epsilon STS electrical, mechanical and environmental specifications. Reference Manuals 160304-00 C00 JBUS/RS232, Installation and User manual. Section Descriptions Quick Start This Quick Start will guide qualified engineers through unpacking and positioning the unit, the equipment, tools, and steps required to perform power input/output connections to prepare the unit for MGE Field Service Engineers to perform on-site final installation and startup.
Epilson STS General Description The Epsilon STS™ system is available in two different cabinet sizes. Dimensions for the cabinets are: 200A cabinet: 72”H x 24”W x 30”D 400A/600A cabinet: 72”H x 38”W x 30”D Both cabinets are designed to provide for top and/or bottom entry of input and output power feeds. The Epsilon STS™...
The SCR outputs for each corresponding phase from both inputs are then connected and fed through an output isolation molded case switch to the output terminals. These SCR's are rated to carry the full 100% load (continuous rated) while operated as stipulated herein and at the maximum ambient temperature specified.

Epilson STS 1.4.1 Plus and PMM Ultra In the PMM Plus configuration, the input of the PMM distribution system accepts two independent AC input sources feeding to the STS. If the preferred input source power is not available, the STS will transfer to the alternate input source, avoiding interruption to the critical load. The output power is conditioned and stepped down to distribution voltage via an isolation transformer, feeding panelboards or main frame circuit beakers.
STS transfers the load to that source if the load is not already being powered by that source. On closure of a bypass switch, the control logic will also shunt trip opposite bypass and input isolation switches if necessary to prevent cross-connec- tion of the two sources.

During normal operation, CB1, 2, 3A and 3B (if installed) are closed and the load receives power from the designated preferred source through either SW1 or SW2 SCR switch. In the event of a preferred source failure, the STS will transfer the load to the alternate source in a fraction of a cycle. If bypassed by closing either CB4 or CB5 bypass switch, CB1, 2, 3A and 3B (if installed) are opened, isolating the static switch section for maintenance.

Scope Setup and Installation guides the User through tools and equipment required for making hardwire connections. Included are power cable connections with wire diagrams for configuring the product to specifications, and obtaining MGE field service assistance for final installation and startup. Final installation and start-up should be completed and performed by a qualified MGE Field Service Engineer.
Epilson STS Cabinet Placement and Environment The complete STS system may consist of more than one cabinet depending on whether the STS is a stand-alone unit or it is used in conjunction with input isolation or output distribution cabinets such as the Power Management Module (PMM ) cabinets.
2.2.1 Conduit Plate Location (bottom entry) Cable entry through the bottom is the standard preferred design for the Epsilon STS™ cabinet. Please see the following figure for the location of the bottom entry conduit plate. Figure 2-2: 200A /400/600A STS Cabinet Footprint and Top View. 200A STS FOOTPRINT 400/600A STS...

N.O. It is possible to individually set each relay and input to N.O. or N.C. mode by setting each switch on SA2 individu- ally. The parameters for relays 1 to 6 are set using SA2 DIP switches 1 to 6 respectively. The parameters for inputs A and B are set using SA2 DIP switches 7 and 8 respectively.
Before starting the Epsilon STS™, be certain that you fully understand the operation of the indicators, controls, and operational sequences. MGE UPS SYSTEMS,INC. offers professional start up services in most countries. It is suggested that before applying power to your Epsilon STS™, your contract with MGE for a professional start up with an MGE Field Engineer.
Scope Operation describes Epsilon STS dures, safety checklists, modes and specifications and theory of operating the Epsilon STS Preparation for Operation Several items must be considered when preparing the Epsilon STS™ system for operation. Configuration Location Environment Electrical Connections The following sections discuss in more detail these items. Pre-Start Up Safety Check List Ensure all power and control wires have been properly connected and securely tightened.
STS. 12. Open (and lock) the Source #1 bypass switch, CB4. The load is now supplied through the static switch. Verify on the LED mimic diagram on the front display panel. Also check the operating status on the LCD screen.
2. Follow the Bypass Procedure to bypass the static switch and connect the load through the bypass switch to the desired bypass source. Isolation switches CB1, CB2, CB3A and CB3B (if installed) will be in the OFF (or Tripped) position.
Manual Transfers The STS can be operated as a manual switch when the Manual Control keyed switch on the front panel is in the ON position, enabling the manual control pushbuttons and some setpoint changes, for the following manual opera- tions: a) Manual Change Preferred Source Pushbutton –...
Mechanical Kirk key interlocks are provided on the two maintenance bypass switches (CB4 and CB5) to prevent an operator from closing both bypass switches at the same time. A single key allows closure of one switch at a time. Additional key interlocks on the two STS input isolation switches (CB1, CB2) to ensure that the STS is on the source that the operator intends to bypass to, are available as an option.
Live System Test (Except with 4-Interlock System) While in maintenance bypass, and with the STS output isolation switch off, the STS can be tested with both sources connected to the STS through the input isolation switches (using the SCR's to make actual transfers).
Bypass Load to Source #1 1. The Source #1 SCR Switch #1 must be indicated closed on the display panel. If not, transfer the load to Source #1 by turning the Manual Control key switch on the front display panel to the “ON” position and pressing the Change Preferred Source Pushbutton.
