This section describes the wiring for transmission cable terminal block of the RJ71CN91.
Wiring for transmission cable terminal block
■Cable installation
Insert the cable into the wire insertion opening with the wiring installation screws loosened, and then tighten the wiring
installation screws at an adequate torque. After the tightening, slightly pull the cable to check that the cable has been
completely clamped.
■Disconnecting cable
Loosen the wiring installation screws for the cable to be disconnected and then pull out the cable.
Precautions
Before connecting the CAN bus cable to the RJ71CN91, be sure to check the terminal name of the transmission cable
terminal block. ( Page 23 Terminal name of terminal block)
When wiring for the transmission cable terminal block, observe the following precautions. Failure to do so may cause electric
shock, short-circuit, disconnection, malfunction, or damage to the RJ71CN91.
• Be sure that wire diameter of the cable is in line with the dimensions listed in this manual. ( Page 25 Wiring Products)
• Twist the end of stranded wire and check that there is no loose wire.
• Do not solder the end of wire.
• Do not connect any cables more than the number specified or with a wire diameter not listed in the specification.
• Completely fix the cable to avoid a direct load to the transmission cable terminal block itself and the connection between
the transmission cable terminal block and the RJ71CN91.
