Cautions

Ordinary Locations

When used in a non-Hazardous (Classified) Location, cables attached to the power port and Pins 1 and 2 of the A/B interface ports must be supplied by a Class 2 circuit, a limited energy circuit or a limited power source (LPS) as per IEC 61010-1, IEC 60950-1, or an equivalent IEC standard. The output should not exceed any of the applicable input entity parameters.

Follow local electrical codes

The wiring method used to install EXO 8's electrical port accessories should be in accordance with local electrical code. Installations are subject to acceptance by the authority having jurisdiction.

Barriers required

If the entity parameters in the Interface port parameters - pins 3&4 diagram and the Interface port functional parameters diagram exceed the requirements of your accessory, then a barrier is required for each interface port when EXO is in Class I, Division 1, Groups A,B,C,D location, or Class I, Zone 0/1, Group IIC location. See the Interface port functional parameters with barriers diagram for more information.

Intrinsic safety warning

Install EXO's electrical port accessories as shown in the electrical diagrams in the Installing Power Port Accessories and Installing Interface Port Accessories sections to ensure intrinsic safety.
