Hazardous Area Classifications and Special Instructions for “Safe
Use” and Installations in Hazardous Locations
Certain nameplates may carry more than one approval, and each approval may have unique installation/wiring
requirements and/or conditions of “safe use”. These special instructions for “safe use” are in addition to, and may
override, the standard installation procedures. Special instructions are listed by approval.
Note
This information supplements the nameplate markings affixed to the product and the LCP100 Local Control Panel instruction
manual (D103272X012
Always refer to the nameplate itself to identify the appropriate certification.

IEC 60079-26:2014
Entity parameters
Refer to drawing GE75327, shown in figure 1, 2, and 3.
Special Conditions for Safe Use
1. The 24 VDC input terminals shall not be used.
2. Under certain extreme circumstances, the plastic enclosure may store an ignition-capable level electrostatic
charge. Precautions shall be taken to prevent the build up of electrostatic charge by charge-generating
mechanisms, e.g. do not rub with a solvent, as indicated on the product nameplate.

Special Conditions for Safe Use
1. 24 VDC+ /24 VDC- and LOOP+ /LOOP- terminals shall not be used simultaneously.
2. Under certain extreme circumstances, exposed plastic and unearthed metal parts of the enclosure may store an
ignition-capable level of electrostatic charge. Therefore, the user/installer shall implement precautions to prevent
the build up of electrostatic charge, e.g. locate the equipment where a charge-generating mechanism is unlikely to
be present and clean with a damp cloth.
