9.2 Network Wiring

See section 3.2, "Network Wiring Equipment," for details on the equipment that makes up the network. This section presents an outline of the wiring laid inside the control panel and outside the control panel. This section also presents individual notes on the twisted pair cables used, the coaxial cables, the AUI cables, and the MAUs.

Basic points in laying out a network

CAUTION

1.When laying network cable, take adequate safety measures and perform all operations in accordance with the relevant standards. See the ISO/IEC8802-3standard for details on laying networks.

2.We strongly recommend hiring a qualified contractor who has specialized knowledge about safety precautions and standards.

3.Avoid installing 10BASE5, 10BASE2 or 10BASE-T networks in environments that have high noise levels. If this is unavoidable, adopt the noise prevention measure described below.

1.Overview of wiring outside the control panel a. Layout environment and required work

Lay out cables in a manner appropriate for the environment. The steps listed in the following table are generally required.

Table 9.1		Wiring Environment and Work Operations
