♦
Antennas for FloBoss 407s equipped for radio communications must be located with an
unobstructed signal path. If possible, locate antennas at the highest point on the site and
avoid aiming antennas into storage tanks, buildings, or other tall structures. Allow sufficient
overhead clearance to raise the antenna.
♦
To minimize interference with radio communications, locate the FloBoss 407 away from
electrical noise sources such as engines, large electric motors, and utility line transformers.
♦
Locate FloBoss 407s away from heavy traffic areas to reduce the risk of being damaged by
vehicles. However, provide adequate vehicle access to aid in monitoring and maintenance.
1.4.3 Compliance with Hazardous Area Standards
The FloBoss 407 has hazardous location approval for Class I, Division 2, Groups A, B, C, and D
exposures. The class, division, and group terms are defined as follows:
Class
defines the general nature of the hazardous material in the surrounding atmosphere. Class
I is for locations where flammable gases or vapors may be present in the air in quantities
sufficient to produce explosive or ignitable mixtures.
Division
defines the probability of hazardous material being present in an ignitable
concentration in the surrounding atmosphere. Division 2 locations are presumed to be
hazardous only in an abnormal situation.
Group
defines the hazardous material in the surrounding atmosphere. Groups A to D are
defined as follows:
♦
Group A - Atmosphere containing acetylene.
♦
Group B - Atmosphere containing hydrogen, gases or vapors of equivalent hazards.
♦
Group C - Atmosphere containing ethylene, gases or vapors of equivalent hazards.
♦
Group D - Atmosphere containing propane, gases or vapors of equivalent hazards.
For the FloBoss 407 to be approved for hazardous locations, it must be installed according to the
National Electrical Code (NEC) Article 501.
