Cisco Aironet 1552 Series for Hazardous Locations Installation Guide
Chapter 2 Before You Begin
Additional Considerations for Hazardous Locations
The access point hazardous location option complies with safety standards for Class I, Division 2/Zone
2 hazardous locations where ignitable concentrations of flammable gases, vapors, or liquids are not
likely to exist under normal operation conditions.
When you select the hazardous location option as part of the ordering process, Cisco configures the
system to contain the new components. Assembly instructions placed in the shipping box provide
information and assembly procedures. The hazardous location option configures the access point as
follows:
•
Do not install a battery in a Hazardous Location environment. Battery packs are not approved for
Hazardous Locations.
• The AC power connections are moved to the inside of the access point by installing an AC entry
board containing a terminal block. To comply with hazardous location requirements, AC power must
be installed through rigid metal conduit to the terminal block.
Caution
The electrical rating for hazardous location installations has a lower voltage rating (100-240
VAC, 50/60 Hz, 1A) than a non-hazardous location installation (100-480 VAC).
Caution
Do not use 12 VDC input connection in hazardous locations.
Caution
Caution: Power injector (AIR-PWRINJ1500-2=) is not certified for installation within
hazardous locations environments.
