  • Page 10: Installation

    Installation Mounting the A36D When mounting the A36D in any configuration, consider the size and weight of the charger. The wall, rack, and/or floor must be able to support the weight of the charger as well as an additional safety factor. Verify the weight of the A36D charger using Tables 1, 2 and 3, and the method of mounting using Table 4 below.

  • Page 11: Rack-Mounting The A36D

    2.1.1 Rack-Mounting the A36D The A36D 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 4D, 9E, 33, 33E, and 39 enclosures are shipped from the factory with the necessary brackets installed for rear mounting on a relay rack The rack mounting bracket for the 4D and 39 enclosures allow for mounting on a 19”...

  • Page 12: Floor-Mounting The A36D

    2.1.2 Floor-Mounting the A36D Floor-mounting the 43, 44, and 72 enclosures is standard. To floor-mount the A36D, install four to six anchor bolts into the floor. Place the charger on the bolts, add appropriate mounting hardware, and tighten securely. The figure below shows the footprint and the bolt size of each A36D enclosure style. All dimensions are in inches. Case Size Bolt Size 11.5”...

  • Page 13: Ac Input Connections

    AC Input Connections Before beginning any work inside the charger, ensure that all incoming AC supply power is off at the main breaker box and the charger’s breakers are off. Check that the source voltage and frequency match the voltage and frequency listed on the charger nameplate.

  • Page 14: Dc Output Connections

    DC Output Connections Before making any of DC output connections, make sure you have read and fully understand the DC Connection Procedure below. Select proper size for the DC wiring from the wire size table on the previous page. If the distance between the charger’s DC output and the DC load exceeds 10 feet, use the Power Cable Guide below to minimize the voltage drop across the wire distance.

  • Page 15: Alarm Connections

    Alarm Connections Seven alarm relays (and 9 alarm LEDs) are included as a standard feature of the A36D. The included alarms are Low DC Current, Low DC Voltage, High DC Voltage, High Voltage Shutdown, AC Failure, Open DC Protection, and Summary alarm.

    2.4.2 Understanding the Alarms HIGH VOLTAGE SHUTDOWN ALARM will trigger and the red “HIGH VOLTAGE SHUTDOWN” LED will turn on if the output DC voltage of the charger rises above the alarm threshold for longer than 20 seconds and there is load on the charger.

  • Page 18: External Temperature Compensation (Option 11W/11Y)

    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 battery charger 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 charger.

  • Page 19: Load Sharing

    Load Sharing All A36D chargers include the Load Sharing feature. Load sharing allows the user to parallel with any identical A36D to share a DC load and therefore reduce the strain on each charger. When connected, identical A36D chargers are forced to share the load within ±5% for individual unit outputs greater than 10% of the rated output. MUST Chargers to be paralleled be the same output (voltage and current).

  • Page 20: Dnp 3.0 / Modbus Scada Interface (Option 21P/21Q)

    DNP 3.0 / Modbus SCADA Interface (Option 21P/21Q) The optional DNP 3.0 / Modbus SCADA Interface Communication Board, allows the user to remotely connect to the A36D battery charger. The board is equipped with four methods of communication; DNP 3.0, Modbus ASCII, Modbus RTU and Modbus TCP.

  • Page 21: Operation

    Operation Starting the A36D All equipment is shipped from the factory fully checked and adjusted based on the model number. Do not make any adjustments unless the equipment has been powered-up and the settings have been determined to be incorrect. Factory Settings The factory settings of the A36D are based on the model number.

  • Page 22: Starting/Stopping The A36D

    3.1.2 Starting/Stopping the A36D Once proper connections are established, energize the power supply by turning on the charger’s AC breaker (the DC breaker should be off). This will charge the capacitors inside the charger and eliminate heavy arcing when the batteries are connected.

  • Page 23: Selecting The Charging Mode

    Selecting the Charging Mode The A36D 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 24: Settings Menu

    3.4.1 Settings Menu In the Settings Menu, the user can access and change various parameters used by the A36D. 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. To enter a submenu, use the ENTER button.

  • Page 29: Output Voltage Adjustments

    Output Voltage Adjustments The output voltage of the A36D charger is set to a default value, but should be adjusted to meet the battery manufacturer recommendations. To adjust the Float and Equalize output voltage, refer to Section 3.4.1.1. Adjustments are recommended to be made with no connections on the DC output terminals of the charger, but can also be done with the battery connected.
