The RED cable always goes to the positive terminal (+) of one
battery. The BLACK cable always goes to the negative terminal
(-) of the other battery. One of the YELLOW cables goes to the
negative pole of one battery (see label on cable) and the other
YELLOW cable goes to the positive pole of the other battery (see
label on cable), linking both batteries serially with the WHITE
connector to give a supp ly of 24 volts. It is better to direct the
cable terminals towards the interior of the box to avoid risk of
contact with the outer box.
