17. The communication error might occur because it enters the state that the terminator is not exist in the link system e Cover shielding of twisted pair cable with the insulator so that the signal wire should not come in contact with the shield line The contact of these lines causes communication error 5 Precautions when Connecting to the Network e When you connect the twisted pair cable to communication connector do not intersect between the parts of cables which peeled coating In the case that cables intersect a communication error may occur e Do not put the communication cable in a duct same as other power lines and a wiring duct of the I O e Separate and lays the communication cables on around 300mm from other ducts e Always turn off the power supply of devices when connecting a communication cable e It is recommended to use clamp terminals when plugging a communication cable into a connector If simply twisting the wires connects the communication cable it may result in the product malfunction due to cable disconnection e Be sure that the connector will not be pulled out by the weight of the cable Pay full attention to wiring so that neither signal lines nor the shielding line will be pulled out during communication e After wiring the communication cable be careful not to put excessive stress on the communication cable as well as the connector It may cause the connector to be pulled out or a broken cable e Allow
