3. Wiring Requirements This section describes how to connect serial devices to the embedded computer You should read and follow these common safety precautions before proceeding with the installation of any electronic device e Use separate paths to route wiring for power and devices If power wiring and device wiring paths must cross make sure the wires are perpendicular at the intersection point NOTE Do not run signal or communication wiring together with power wiring in the same wire conduit To avoid interference wires with different signal characteristics should be routed separately e Use the type of signal transmitted through a wire to determine which wires should be kept separate The rule of thumb is that wiring that shares similar electrical characteristics can be bundled together e Keep input wiring and output wiring separate e It is advisable to label the wiring to all devices in the system NT ENTION Safetv First Be sure to disconnect the power cord before installing and or wiring your W315 325 Wiring Caution Calculate the maximum possible current in each power wire and common wire Observe all electrical codes dictating the maximum current allowable for each wire size If the current goes above the maximum ratings the wiring could overheat causing serious damage to your equipment Temperature Caution Be careful when handling the unit When the unit is plugged in the internal components generate heat and
