Installation and mounting
The minimum safety distance is defined by several parameters, including:
 stopping/run-down time of the machine or system
(
the stopping/run-down time is shown in the machine documentation or must be
measured under worst case conditions.)
 response time of the protective device (see chapter 11.2 “Response time” on page 58)

reach or approach speed
 resolution of the safety light curtain
 other parameters that are stipulated by applicable standards and regulations
5.1.2 Hazard approach
The minimum safety distance changes based on the implementation of the protective
device. Most applications use a perpendicular (e.g. vertical as shown below) mounting of a
safety light curtain. However, it may be necessary to install the safety light curtain in a
horizontal or angular orientation. The following figure provides examples of perpendicular
(vertical), horizontal and angular implementations of a safety light curtain.
