HAZARD
This equipment must be grounded. Improper grounding, setup, or usage of the system can
cause electric shock.
• Turn off and disconnect power at main switch before disconnecting any cables and before
servicing or installing equipment.
• Connect only to grounded power source.
• All electrical wiring must be done by a qualified electrician and comply with all local codes
and regulations.
• Do not expose to rain. Store indoors.

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.
• Installation should be in accordance with ANSI/ISA RP12.06.01 “Installation of Intrinsically
Safe Systems for Hazardous (Classified) Locations” and the National Electrical Code®
(ANSI/NFPA 70).
• Installation in Canada should be in accordance with the Canadian Electrical Code, CSA
C22.1, Part 1, Appendix F.
• For ATEX, install per EN 60079–14 and applicable local and national codes.
• Equipment that comes in contact with intrinsically safe terminals must meet the entity
parameter requirements specified in Control Drawing 16M169. See Appendix A in Manual
332013. This includes safety barriers, DC voltage meters, ohmmeters, cables, and
connections. Remove the unit from the hazardous area when servicing.
• If a printer, computer, or other electrical component is connected, it must be used in
conjunction with a safety barrier.
• Without the safety barrier, the equipment is no longer intrinsically safe and must not be
operated in hazardous locations, as defined in article 500 of the National Electrical Code
(USA) or your local electrical code.
• Do not install equipment approved only for non-hazardous location in a hazardous area. See
the ID label for the intrinsic safety rating for your model.
• Do not use intrinsically safe equipment with a power supply that has no barrier. Intrinsic
safety may be compromised.
• Ground the power supply. A voltage limiting safety barrier must be properly grounded to be
effective. For proper grounding, use a 12 gauge minimum ground wire. The barrier’s ground
must be within 1 ohm of true earth ground.
• Do not remove any cover until power has been removed.
• Do not substitute system components as this may impair intrinsic safety.
