	CO-HC-ESV-3P⋅7/0.2	Hirakawa Hewtech Corp.

Refer to pages 11 and 12 for the connector pin layouts. Refer to 2-3-5 Recom- mended RS-232C Wiring Examples and 2-3-6 Recommended RS-422A/485 Wiring Examples for wiring examples, and to 2-3-7 Wiring Connectors for wiring methods.

Standard cables are available for connection to personal computers and PTs. Refer to Section 4 Host Link Communications for personal computer cables and to your PT user’s manual for PT cables.

2-3-2 Wiring Precautions

•Before connecting or disconnecting the communications cables, always make sure that the PC is turned OFF.

•Tighten the communications connector screws firmly with your fingers.

•Serial Communications Boards can be connected to various devices. For compatibility, refer to the operation manuals for the devices to which they are to be connected.

2-3-3 Reducing Electrical Noise for External Wiring

Observe the following precautions for external wiring.

•When multi-conductor signal cable is being used, avoid using I/O wires and other control wires in the same cable.

•If wiring racks are running in parallel, allow at least 300 mm between the racks.

Communications cables

PC power supply and general control circuit wiring

Power lines

Low-current cables

300 mm min.

Control cables

300 mm min.

Power cables

Ground to 100 Ω or less.

•If the I/O wiring and power cables must be placed in the same duct, they must be shielded from each other using grounded steel sheet metal.
