Chapter 6 Installation and Wiring
See Specifications on page 127 for certification information and ratings. The
requirements that are defined in this appendix, for example, power supply, cables,
and ambient conditions, must be observed and maintained to allow the safety
function.
Use appropriate screws, bolts, and/or nuts to mount the sticks and plug-ins to
avoid damage.
Do not over-torque the mounting hardware:
• The required screwdriver type for installation of the plug-ins is a Phillips
tip screwdriver for M2 x 8 Phillips screw. Maximum torque is 0.38 N•m
(3.36 lb•in).
• The required screwdriver type for installation of the standard top/ bottom
mounting kit is a Phillips tip screwdriver for M3 x 10 Phillips DIN 965 A
screw. Maximum torque is 0.7 N•m (6.19 lb•in).
Only use the designated mounting holes of the mounting bracket.
Use only fixed, stable, and sturdy mounting posts or frames to mount a 450L-B
GuardShield safety light curtain system.
For the installation of the plug-ins, see Electrical Installation on page 88
.
Determine the Safety
Distance
The light curtain must be mounted with proper safety distance:
•From the point of danger
•From reflective surfaces.
To help prevent a person from reaching through the protective field to a
dangerous area (while the machine is still moving), both points must be
considered in an installation.
The calculation of point one varies depending on the region (country) where it is
operated.
U.S. Safety Distance Formula
This distance, referred to as the safety distance, must be properly calculated
before determining the safety light-curtain protective height and mounting the
light curtains on the machine. Failure to calculate this safety distance properly
can result in operator injury.
ATTENTION: The GuardShield safety light curtains must be mounted at a
sufficient distance from the pinch point or point of operation hazard. This
distance helps confirm that the machine stops before a finger, hand, arms, or
body reach the hazard.
