Page 6: Model Scope/General Description
Understanding the Model Number The ESCR125 model number is coded to describe the features that are included. Find the model number on the nomenclature nameplate of the charger. Follow the chart below to determine the configuration of the battery charger. -
Page 7: Installation
Installation Mounting the ESCR125 For user convenience, the ESCR125 can be wall or floor mounted. The 4 enclosure can also be rack mounted. Be sure that the Wall or Floor planned for installation can support the weight of the ESCR125. -
Page 8: Floor Mounting
1.1.3 Rack Mounting (4 Enclosure Only) The ESCR125 can be installed in most relay racks with standard EIA hole spacing. If a relay rack is needed, they are available for purchase from La Marche. The 4 enclosures are shipped from the factory with the necessary brackets installed for rear mounting on a 19”... -
Page 9: Electrical Connections
1.2.1 Changing Transformer Taps The ESCR125 accepts standard input voltages of 120, 208, or 240 VAC by changing the connections to the input terminals. Before changing the AC input taps, assure that AC supply and DC loads to the ESCR125 are turned off and locked out. -
Page 10: Ac Input Connections
1.2.2 AC Input Connections Before beginning any work inside the charger, ensure that all incoming AC supply is de-energized. Verify that no voltage is present inside the case by using a voltmeter at all input and output terminals. Check that the source voltage and frequency match the charger front nameplate specifications. - Page 11 Power Cabling Guide Use the following formulas and table to determine proper wire size for minimal voltage drop. At distances exceeding 10 feet, the DC wire size should be chosen to keep the voltage difference between the charger’s DC output terminals and the battery at less than 1/2 volt when the charger is fully loaded.

Page 12: Standard Alarms
1.2.4 Standard Alarms Four alarms are included as a standard feature of the ESCR125. The included alarms are High DC Voltage, Low DC Voltage, Charger Failure, and AC Failure. Each alarm includes a form “C” contact, enabling the user to connect remote annunciators. -
Page 13: External Temperature Compensation (Option 11W/11Y)
Alarm Connections Before making any connections to the ESCR125, ensure that the AC Power is off at the main breaker box and that both of the charger’s breakers are off. Verify that no voltage is present by using a voltmeter at all input and output terminals. -
Page 14: Operation
2.1.3 Start-Up Sequence Upon powering up the ESCR125, the LCD will display “La Marche ESCR”. During the start up sequence, the Low DC Voltage alarm will be temporarily activated. The display will show “Float Mode” and the output Voltage and Current of the Charger will slowly ramp up. -
Page 15: Front Panel Display
Front Panel Display After the ESCR125 has completed start up, the “AC ON” indicator on the front panel and either the “Float” or “Equalize” indicator on the front panel will be lit. The LCD will display the system DC output voltage and DC output current on line one. -
Page 16: Led Indicators/Alarms
LCD Display – The LCD Display shows the output DC voltage and output DC amperage of the ESCR125 at all times. The second line of the display shows the mode of the charger, as well as displaying the different alarm conditions, should they occur. -
Page 17: Configuration Mode
Equalize cycle starts automatically if battery voltage falls below the Low Voltage Alarm set point In any Equalize Mode, the ESCR125 will return to Float Mode at the end of the Equalize cycle. Current Limit – Allows adjustment of the current limit from 50% to 110% of rated output. -
