Page 12: Floor-Mounting The A36D (All Enclosures)
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. -
Page 13: Changing Transformer Taps
NOTE: The A36D is wired at the factory for 240 VAC, except on special request. Before changing the PT taps, be sure that AC supply and DC loads to the A36D are turned off and locked out. Verify that no voltage is present by using a voltmeter at all input and output terminals. Turning off the AC and... -

Table 6 – 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 15: 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 16: 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. Each alarm includes two sets of form ‘C’ contacts, enabling the user to connect multiple remote annunciators. -
Page 17: Alarm Connection Procedure
Alarm Connection Procedure Before making any connections to the A36D, ensure that the AC power is off at the main breaker box and the charger’s breakers are off. Verify that no voltage is present by using a voltmeter at all input and output terminals. -
