English 11PRECAUTIONSUse ring-type crimp-style terminals for connecting wires tothe power supply terminal board. If unavailable, observe thefollowing points when wiring.• Do not coat stranded wires with solder.• Do not connect wires of different gauge to the same powersupply terminal. (Looseness in the connection may causeoverheating.)• When connecting wires of the same gauge, connect themaccording to the righthand figure.• Use the specified electric wire. Connect the wire securelyto the terminal. Lock the wire down without applying exces-sive force to the terminal.• Use an appropriate screwdriver for tightening the terminalscrews. A screwdriver with a small head will strip the head and make proper tightening impossible.• Over-tightening the terminal screws may break them.〈Precautions for grounding terminal connections〉Be sure to connect the ground wire so that the cup washer will come out ofthe cutout part.(Otherwise, the effect of grounding may be lost due to the insufficient contactof the ground wire.)• Transmission wiring can be branched to 16 lines. Branched lines cannot be further branched.(Refer to Fig. 5)• Do not connect 200 V to the terminal block for transmission wiring by any means.Otherwise, the entire system will be damaged.• Be sure to keep the following limits, or otherwise a transmission error may result.• Wiring length: 1000 m max.• Total wiring length: 2000 m max.• Number of branches: 16 max.Tightening torque (N·m)Remote controller/transmission wiring terminalblock (M3.5) 0.79~0.97Power supply terminal block (M4) 1.18~1.44Grounding wire (M4) 1.44~1.94Electric wireRing-type crimpstyle terminalAttach insulation sleeveConnect wires of thesame gauge to bothsides.Do not connectwires of the samegauge to one side.Do not connectwires of differentgauges.Cup washerCut out sectionRing-type crimpstyle terminalSubbranchingBranchF1 F2 F1 F2 F1 F2F1 F2 F1 F2Fig. 5
