Important Information Regarding the Use of Safety Switches
In the United States, the functions that Banner safety switches are intended to perform are regulated by the Occupational Safety and
Health Administration (OSHA). Whether or not any particular safety switch installation meets all applicable OSHA requirements depends
upon factors that are beyond the control of Banner Engineering Corp. These factors include the details of how the safety switches are
applied, installed, wired, operated, and maintained.
Banner Engineering Corp. has attempted to provide complete application, installation, operation, and maintenance instructions. This in-
formation is found in the instruction manual packaged with each safety switch. In addition, we suggest that any questions regarding the
use or installation of safety switches be directed to the factory applications department at the telephone numbers or address shown
below.
Banner Engineering Corp. recommends that safety switches be applied according to the guidelines set forth in international (ISO/IEC)
standards listed below. Specifically, Banner Engineering Corp. recommends application of these safety switches in a configuration which
meets safety category 4, per ISO 13849 (EN954-1).
In addition, the user of Banner safety switches has the responsibility to ensure that all local, state, and national laws, rules, codes, and
regulations relating to the use of Banner safety switches in any particular application are satisfied. Extreme care is urged that all legal
requirements have been met and that all installations and maintenance instructions are followed.
