7 Notes for Intrinsically Safe Installation<br />

7.1 Hazardous Locations<br />

Refer to the device label for the description of the environment in which the device may be installed.<br />

7.2 Field Wiring<br />

Intrinsically Safe wiring must be made with grounded shielded cable or installed in grounded metal<br />

conduit.<br />

The electrical circuit in the hazardous area must be capable of withstanding an A.C. test voltage of 500<br />

volts R.M.S. to earth or frame of the apparatus for 1 minute.<br />

Installation must be in accordance with <strong>Masoneilan</strong> guidelines. The installation including the barrier<br />

earthing requirements must comply with the installation requirements of the country of use.<br />

Factory Mutual requirements (USA): ANSI/ISA RP12.6 (Installation of Intrinsically Safe Systems for<br />

Hazardous (Classified) Locations) and the National Electrical Code, ANSI/NFPA 70. Division 2<br />

installations must be installed per the National Electrical Code, ANSI/NFPA 70. See 7.3.2. In group A<br />

installations, conduit seal required within 18 inches of enclosure entrance.<br />

CSA requirements (Canada): Canadian Electrical Code Part 1. Division 2 installations must be installed<br />

per the Canadian Electrical Code Division 2 Wiring Methods. See 7.3.2.<br />

ATEX requirements (EU): Intrinsically safe installations must be installed per EN60079-10 and<br />

EN60079-14 as they apply to the specific Category.<br />

7.3 Entity Requirements<br />

Cable capacitance and inductance plus the I.S. apparatus unprotected capacitance (Ci) and inductance<br />

(Li) must not exceed the allowed capacitance (Ca) and inductance (La) indicated on the associated<br />

apparatus. If the optional Hand Held Communicator is used on the Hazardous Area side of the barrier,<br />

then the capacity and inductance of the communicator must be added and the communicator must be<br />

agency approved for use in the hazardous area. Also, the current output of the Hand Held<br />

Communicator must be included in the current output of the associated equipment.<br />

The barriers may be active or passive and from any certified manufacturer as long as the barriers comply<br />

with the listed entity parameters.<br />

7.3.1 <strong>SVI</strong> <strong>II</strong> <strong>ESD</strong> 4-20 mA IN Terminals (+) and (-)<br />

These terminals power the <strong>SVI</strong> <strong>II</strong>-<strong>ESD</strong>. The barrier is the Controller Output Type, for example MTL<br />

728.<br />
