For information on the requirements that must be met for safe integration of the safety
la
ser scanner into the controller and electronics of the machine: see "Integrating the
equipment into the electrical control", page 60.
Mounting should be completed before electrical installation.
DANGER
D
eath or severe injury due to electrical voltage and/or an unexpected startup of the
machine
b
Make sure that the machine is (and remains) disconnected from the voltage
supply during mounting and electrical installation.
b
Make sure that the dangerous state of the machine is and remains switched off.
DANGER
H
azard due to lack of effectiveness of the protective device
In the case of non-compliance, it is possible that the dangerous state of the machine
may not be stopped or not stopped in a timely manner.
b
Make sure that the following control and electrical requirements are met so the
safety laser scanner can fulfill its protective function.
b
Use suit
able power supply.
b

safety laser scanner.
b
Check that all earthing points are connected with the same ground potential.
b
Voltage must be supplied in accordance with SELV/PELV (IEC 60204-1) for all
devices that are electrically connected to the safety laser scanner.
b
Connect functional earth correctly.
NOTICE
Enc
losure rating IP65 only applies if the safety laser scanner is closed and the system
