Part name: JIG KIT 6ZM-2Part No.: SV-J00-016-010 1) How to assemble the jig Assemble the jig referring to Fig-1. 1Separate the supplied two 6P flat cables, and fabricate the one 3P wire,

6、 the two 2P wires and the one 1P wire. 2Attach the photo sensor to the jig C.B. by soldering. (Refer to Fig-1 and indication on the jig C.B. for the direction of attaching the photo sensor.) 3Attach the outside terminal of the timing switch to the jig C.B. with soldering. (At this time, do not solde

7、r the timing switch to the motor terminal land.) 4Connect the other terminal of the timing switch to the GND terminal of the jig C.B. using a wire. 5Connect the wire that are separated in step 1 by soldering, to the jig C.B. as shown in Fig-1. 2) How to attach the jig Attach the jig referring to Fig
