3.7.6 Diagonal and Right-Angle Mounting
IMPROPER INSTALLATION FOR POINT-OF-OPERATION
To prevent operating personnel from access to danger zone, install hard guard or right-
angle mounting if distance between danger zone and closest light beam is greater than 70
millimeters (2.8 in.).
Failure to comply with these instructions could result in death or serious injury.
For point-of-operation guarding, the safety light curtain(s) and any hard guarding must be
installed so that no person can stand between the light curtain and the danger zone
without being detected. Installation may require additional hard guarding, horizontal or
diagonal mounting of the light curtain, or additional light curtains mounted at right angles
to each other.

< 70 mm/2.75 in.
A right-angle mounting arrangement may be used if the altered resolution at the joint is
acceptable to the local regulatory agency. The emitters and receivers units should be
mounted with opposite orientations to prevent mutual interference or cross-talk(see figure
below).
