AC installation
Connecting the Lithiumate Lite master to the AC power

NOTE: the input power connection depends on the revision level of the BMS master: Rev C uses pins 1 and 4, Rev F uses pins 3 and 4.

User supplied required parts:

  • 3-conductor cable that is UL or CSA or CE rated, and that is rated for the AC voltage and for the charger's input current
  • AC power inlet
  • Plug for the charger's AC power input
  • Fuse rated for 1 A and the AC voltage and for the charger's input current (2 fuses for 220 Vac split-phase operation)
  • Fuse holder for the above fuse(s)

Route that cable:

  • From the vehicle's AC power inlet
  • To a fuse holder with a fuse that is rated for 1 A and the AC voltage and for the charger's input current (2 fuses for 220 Vac split-phase operation)
  • To the master AC power plug

Connect the cable to the vehicle's AC power inlet:

  • Black (or brown) to the Hot (or Line 1)
  • White (or blue) to the Neutral (or Line 2)
  • (Note that the ground wire (green or yellow-green) is not used by the BMS master.)

Connect the cable to the fuse holder:

  • Cut the black (or brown) wire in two and wire at either end of the fuse
  • For 220 Vac split-phase operation), cut the white (or blue) wire in two and wire at either end of the other fuse

Connect the the AC power to the master:

  • Unplug the 4-screw green terminal block from the master (the screw numbers, 1 to 4, are shown on the master's label)
  • Rev F master:
    • Strip the black (or brown) wire; connect to screw # 3 of the green connector
    • Strip the white (or blue) wire; connect to screw # 4 of the green connector
    • Note that the two wires go to the two positions in the green terminal block closest to the outside edge of the box
  • Plug the 4-screw green terminal block back into the master
  • Note that the black (or brown) wire goes to the position labeled "L" (for "line"), and the white (or blue) wire goes to the position labeled "N" (for "neutral")
  • Rev C master:
    • Strip the black (or brown) wire; connect to screw # 4 of the green connector
    • Strip the white (or blue) wire; connect to screw # 1 of the green connector
    • Note that the two wires go to the two outside positions in the green terminal block
  • Plug the 4-screw green terminal block back into the master
  • Note that the black (or brown) wire goes to the position labeled "L" (for "line"), and the white (or blue) wire goes to the position labeled "N" (for "neutral")
  • BMS master, connection point highlighted
    Connection location or rev F master. NOTE: rev C master is uses pins 1 and 4 instead!

    Connect the AC power to the AC source:

    1. Earth (green / yellow):
      • Run a line from the Earth contact of the AC inlet to the chassis
    2. Neutral (blue or white):
      • Run a line from the the Neutral contact of the AC inlet to the AC inputs of the BMS controller and the 12 V charger
    3. Hot (brown or black):
      • Run a line from the the Hot (Line) contact of the AC inlet, to a 1 A fuse rated 250 Vac
      • Run a line from the other end of the fuse to the AC inputs of the BMS controller and the 12 V charger
