4.2General Wiring Practices

WARNING

Qualified personnel should perform wiring only.

Safety precaution

WARNING

A disconnect switch must be installed to break all current carrying conductors. Turn off power before working on conductors. Failure to observe this precaution may result in serious personal injury.

WARNING

An external disconnect switch is required for any hazardous voltage connections to the relay outputs.

Avoid damage to components

ATTENTION

This equipment contains devices that can be damaged by electrostatic discharge (ESD). As solid-state technology advances and as solid-state devices get smaller and smaller, they become more and more sensitive to ESD. The damage incurred may not cause the device to fail completely, but may cause early failure. Therefore, it is imperative that assemblies containing static sensitive devices be carried in conductive plastic bags. When adjusting or performing any work on such assemblies, grounded workstations and wrist straps must be used. If soldering irons are used, they must also be grounded.

A grounded workstation is any conductive or metallic surface connected to an earth ground, such as a water pipe, with a 1/2 to 1 megohm resistor in series with the ground connection. The purpose of the resistor is to current limit an electrostatic discharge and to prevent any shock hazard to the operator. The steps indicated above must be followed to prevent damage and/or degradation, which may be induced by ESD, to static sensitive devices.

Wiring for immunity compliance

In applications where either the power, input or output wiring are subject to electromagnetic disturbances, shielding techniques will be required. Grounded metal conduit with conductive conduit fittings is recommended.

Connect the AC mains through a fused disconnect switch.

Conform to code

Instrument wiring should conform to regulations of the National Electrical Code.
