INTRINSIC SAFETY
Intrinsically safe equipment that is installed improperly or connected to non-intrinsically safe equipment
will create a hazardous condition and can cause fire, explosion, or electric shock. Follow local
regulations and the following safety requirements.
•
Be sure your installation complies with national, state, and local codes for the installation of electrical
apparatus in a Class I, Division 1, Group D, or Zone 0, or 1, Group IIA (as applicable) Hazardous Loca-
tion, including all of the local safety fire codes. For the United States, this includes NFPA 33, NEC 500
and 516, and OSHA 1910.107.
•
Equipment that comes in contact with the G-Barrier's intrinsically safe terminals must be rated for
Intrinsic Safety. This includes DC voltage meters, ohmmeters, cables, and connections.
•
Do not install the G-Barrier, which is non-intrinsically safe, in a hazardous area, as defined in Article
500 of the National Electrical Code (USA) or your local electrical code.
•
The G-Barrier must be properly grounded to be effective. For proper grounding, use the ground wire
provided (or a 12-gauge minimum ground wire), and the G-Barrier's ground must be within 1 ohm of
true earth ground. For more information, see Installation.
•
Do not operate the G-Barrier module with the cover removed.
•
All electrical wiring must be done by a qualified electrician and comply with all local codes and regu-
lations.
•
Do not alter or modify equipment. Alterations or modifications may void agency approvals and create
safety hazards.
