Page 8: Equipment Handling
Equipment Handling Storing the AUPS If the AUPS is to be stored for more than a few days after delivery, it should be stored within its shipping container. The location chosen for storage should be within an ambient temperature of -40 to 185° F (-40 to 85°C) with a non-condensing relative humidity of 0 to 95%. -
Page 9: Installation
Installation Mounting the AUPS When mounting the AUPS in ANY configuration, consider the size and weight of the unit. The floor must be able to support the weight of the unit, as well as an additional safety factor. Verify the method of mounting and the weight of the AUPS using Tables 1 and 2. -
Page 10: Changing Transformer Taps - Rectifier Ac Input
Changing Transformer Taps – Rectifier AC Input NOTE: This procedure refers only to AUPS systems that accept three input voltages of 120, 240, and 208 VAC at the Rectifier AC Input [Voltage code: ABD]. Before wiring AC power to the AUPS, check the wiring of the power transformer PT, to be sure it is connected for the correct AC input voltage. -
Page 11: Making The Ac Connections
Table 4 – AC/DC & Ground Wire Size Minimum Requirements (All wires specified in the table are rated at 90 °C or 194 °F) NOTE: These are recommended sizes per La Marche Standards. The National Electrical Code (NEC) and Local Wiring Codes must be followed. -
Page 12: Rectifier Ac Input Connection Procedure
2.3.1 Rectifier AC Input Connection Procedure First, connect an adequate earth ground lead (use Table 4 for sizing) to the terminal marked with a “GROUND” symbol inside the system. Run the Rectifier AC input wiring to terminals marked L1 and L2 or L3 of the terminal block TB1 inside the system (for systems with transformer taps, use Table 3 for input connections). -
Page 13: Making The Dc Input/Battery Connections
Making the DC Input/Battery Connections Before making any of DC input connections, make sure you have read and fully understand the DC Connection Procedure below. Ensure that the Battery breaker is set to the OFF position. Select proper size for the DC wiring from Table 4. -
Page 14: Alarm Connections
Alarm Connections Eight alarm relays (and 10 alarm LEDs) are included on the rectifier section as a standard feature of the AUPS. The included alarms are Low DC Current, Low DC Voltage, High DC Voltage, High Voltage Shutdown, AC Failure, Negative Ground Detection, Positive Ground Detection, and Summary. Five status indicator relays (and 11 status LEDs) are included on the inverter section as a standard feature of the AUPS. -
Page 15: Figure 8 - S2A-240 Display Board
LEDs are provided on the inverter section for the following status indicators: Phase Lock, Auto Retransfer, Manual Retransfer, Load on Preferred Source, Load on Alternate Source, Utility Available, Inverter Available, Load Voltage, Load Current, Load VA, Utility Voltage, Utility Frequency, Inverter Voltage, and Inverter Frequency. -
Page 16: Alarm Connection Procedure
2.5.1 Alarm Connection Procedure Before making any connections to the AUPS, ensure that the AC power is off at the main breaker box and that all of the system’s breakers are off. Verify that no voltage is present by using a voltmeter at all input and output terminals. -
Page 17: Understanding The Alarms
Installing External Temperature Compensation (Option 11W/11Y) The natural voltage of a battery changes as a function of temperature change. As the battery temperature rises, the effective voltage of the battery decreases. Without Temperature Compensation, the rectifier will always produce a set constant output voltage. As the battery temperature increases, this constant voltage will then induce a higher output current from the rectifier. -
Page 18: Enabling/Disabling Ground Detection
1.5mA is reached (or exceeded). NOTE: La Marche Mfg. Co. is primarily a manufacturer of battery chargers and not ground detection systems. If a more precise system is needed, many ground detection systems are compatible with La Marche products. -
Page 19: Remote Equalize
Remote Equalize A terminal is provided on the AUPS (RE) for a Remote Equalize function. The rectifier may be remotely forced into Equalize by connecting the “RE” terminal (on TS-5 terminal) to negative. CAUTION: Damage to the unit will result if the Remote Equalize Terminals are shorted to any other AC or DC voltage source or ground on positive grounded chargers. -
Page 20: Operation
Operation Starting the AUPS All equipment is shipped from the factory fully checked and adjusted based on the customer order. Do not make any adjustments unless the equipment has been powered-up and the settings have been determined to be incorrect. 3.1.1 Checking the Installation Before attempting to start up the AUPS, check and verify that all connections are correct. -
Page 21: Factory Settings
Stopping the AUPS Procedure When shutting down the AUPS, switch off the ON/OFF switch (inverter section) first, and then switch of the AC breakers, followed by the DC breakers. Factory Settings All AUPS systems are default set based on 12, 24, or 60 lead acid cells for 24VDC, 48VDC, or 125VDC respectively. -

Page 24: Digital Control Board - Rectifier Section
Digital Control Board – Rectifier Section The AUPS is available with an LCD or VFD digital control board for the rectifier section. Figure 13 - Rectifier Front Panel After the AUPS has completed the startup sequence, AC ON and FL green LED indicators on the rectifier front panel will be lit, additional indicators will be lit according to the system’s status as pictured above in Figure 13. -
Page 25: Selecting The Charging Mode - Rectifier Section
Selecting the Charging Mode – Rectifier Section The AUPS rectifier has two different settings for DC output voltage, Float Mode and Equalize Mode. Float charging mode is used for all normal battery charging needs. Equalize mode is used when it is necessary to Equalize (or balance) the level of charge across all cells present in the battery. -
Page 26: Settings Menu
3.6.1 Settings Menu In the Settings Menu, the user can access and change various parameters used by the rectifier section of the AUPS. To access the Settings Menu, press the MENU button, select “Settings Menu”, and press the ENTER button. Once in the Settings Menu, the user can navigate the menus with the up and down arrows. -
Page 27: Advanced Settings
Alarm Thresholds The Alarm Thresholds setting allows the user to determine the current or voltage value at which an alarm triggers. The threshold can be changed for Low Current Alarm, Low Current Alarm Reset, Overload Alarm, Low Voltage Alarm, Low Voltage Alarm Reset, End of Discharge Alarm, High Voltage Alarm, and High Voltage Shutdown Alarm. - Page 28 Equalize Timer Hours The Equalize timer hours setting changes the amount of time that the rectifier remains in the Equalize charging cycle once activated. When an Equalize cycle is started the rectifier will remain in Equalize Mode until the time selected by this setting has passed.

Page 34: Adjusting Parameters - Inverter Section
Adjusting Parameters – Inverter Section All equipment is shipped from the factory fully checked and adjusted based on the customer order. Do not make any adjustments unless the equipment has been powered-up and the settings have been determined to be incorrect. - Page 35 Inverter Voltage Window Upper Limit The maximum allowable/acceptable limit on the Inverter Voltage defaults to the Output Voltage setting +10%. Thus, an inverter with an output voltage of 120 Volts will have a default setting of approximately 132 Volts. There are no limits on max and min settings for this. The display units are in Volts-RMS. Due to display resolution, the ability to adjust this setting to an exact voltage may not be possible.
