h) Once finished, turn the current down to < 1A, disconnect the load, and then turn off the power supply.

Battery Charging Operation
Warning:
at no time should the battery be connected to the power supply when the power supply is turned off, or
with the output voltage of the power supply set to lower than the battery voltage.
e) Find out if the battery has a maximum allowed charging current that is lower than the maximum rated current
of the power supply. If yes, set the current limit following instructions in section 3-4. Use a magic marker to mark
the position of the coarse current knob (3). If not, skip this step.
f) Turn the coarse current knob (3) to minimum position or slightly above zero while still keeping the CV light on.
Use knobs 12 and 13 to set the voltage to desired charging voltage recommended by the battery manufacturer.
g) Connect the battery while making sure that the polarity is correct (+ to + and – to –). Disconnect the battery
immediately if you made a mistake. For output more than 10A, you must use the rear terminals.
Warning:
damage caused by wrong polarity is not under warranty.
h) Turn the coarse current knob up to the marked position, or the maximum position if it’s safe to charge at the
maximum output of the power supply. If the CC light is on, adjust this knob slightly to make sure the current
meter is reading the maximum charging current. If the CV light is on, it simply means that the battery is not
depleted enough to charge at the maximum current allowed.
j) Watch the charging progress, when the current is below 1A or 1/10 of the maximum charging current, it is
probably time to stop. Make sure the AC power never goes off line during the charging process.
