PRECAUTIONS
Use ring-type crimp-style terminals for connecting wires to
the power supply terminal board. If unavailable, observe the
following points when wiring.
• Do not coat stranded wires with solder.
• Do not connect wires of different gauge to the same power
supply terminal. (Looseness in the connection may cause
overheating.)
• When connecting wires of the same gauge, connect them
according to the righthand figure.
• Use the specified electric wire. Connect the wire securely
to the terminal. Lock the wire down without applying exces-
sive force to the terminal.
• Use an appropriate screwdriver for tightening the terminal
screws. 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 of
the cutout part.
(Otherwise, the effect of grounding may be lost due to the insufficient contact
of 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.
