5 Installation and mounting
This chapter describes the preparation and completion of the installation of the C4000
Select. The mounting requires two steps:
determining the necessary safety distance
mounting with swivel mount or side bracket, rigid or pivoting mounting bracket
The following steps are necessary after mounting and installation:
completing the electrical connections (chapter 6 “Electrical installation” on page 43)
aligning sender and receiver (chapter 7.2 “Aligning sender and receiver” on page 47)
testing the installation (chapter 7.3.1 “Tests before the first commissioning” on
page 48)
5.1 Determining the minimum safety distance
The C4000 Select must be mounted with an adequate safety distance:
to the hazard or hazardous area
from reflective surfaces
No protective function without sufficient safety distance!
You must mount the C4000 Select with the correct safety distance to the hazardous
area. Otherwise the safe protection of the C4000 Select system is not provided.
Risk of failure to detect!
Persons who are in the hazardous area but not in the light path between sender and
receiver are not detected by the C4000 Select system. It is therefore to be ensured that
the hazardous area is fully visible and any dangerous state can only be initiated if there
are no personnel in the hazardous area.
The applicable legal and official regulations apply to the use and mounting of the C4000
Select safety light curtain and any associated protective devices. These regulations vary
depending on the application.
5.1.1 Minimum safety distance to the hazardous area
A minimum safety distance must be maintained between the safety light curtain and the
hazardous area. This ensures that the hazardous area can only be reached when the
dangerous state of the machine is completely at an end.
You must ensure that the minimum safety distance requirements are implemented
correctly!
The minimum safety distance is calculated to ensure that personnel cannot reach a hazar-
dous condition before the hazard ceases to exist. You must ensure that the implementa-
tion of the safety system(s) (e.g. the protective device, safety interface and associated
actuator(s)) adheres to the requirements of applicable local, regional and national
standards and regulations. Consult applicable standards and regulations for additional
requirements that may pertain to your application.
You must also take preventive measures to ensure that personnel cannot reach over, un-
der, around or through the protective device undetected. Personnel must be detected by
the safety light curtain when approaching the hazard.
