In case of Model DA302D, battery holder is an integrated part of switch.
Therefore, no lead wires are used between battery holder and switch.

Wiring diagram P 6 / 6
(1) When soldering the lead wires to terminals of switch and over current relay,
pass the lead wires from inside to outside as illustrated in Fig. A-1, instead of Fig. A-2.

(2) When assembling motor to housing R, its + terminal (white lead wire side) has to come
on the switch side as illustrated in Fig.B.

(3) Pass the following lead wires between rib A and B, and fix them with lead holder below.
* Red lead wire of over current relay to be connected to switch
* White lead wire of over current relay to be connected to DC motor
* 3 FET lead wires to be connected to switch

(4) Assemble heat sink deep in the housing R firmly. Otherwise, impossible to assemble housing L.
(5) Be careful, not to pinch the lead wires at the portion surrounded with circle, when assembling housing L.
