Safety
Important information
DANGER
Hazard due to electrical voltage
Hazard due to unexpected starting of the machine
b
Make sure that the machine is (and remains) disconnected from the power supply
during the electrical installation.
b
Make sure that the dangerous state of the machine is (and remains) switched off
during electrical installation.
b
Make sure that the outputs of the multiple light beam safety device do not affect
the machine during electrical installation.
b
Only use an appropriate voltage supply,
.
DANGER
Hazard due to lack of effectiveness of the protective device
The dangerous state may not be stopped in the event of non-compliance.
b
Always connect the two OSSDs separately. The two OSSDs must not be connected
to each other.
b
Connect the OSSDs such that the machine controller processes both signals sepa‐
rately.
DANGER
Hazard due to lack of effectiveness of the protective device
The dangerous state may not be stopped in the event of non-compliance.
b
Prevent the formation of a potential difference between the load and the protec‐
tive device.
DANGER
Hazard due to lack of effectiveness of the protective device
Malfunctions can occur if unused inputs are wired incorrectly.
b
Unused inputs must either not be connected or be permanently switched to LOW.
DANGER
Hazard due to lack of effectiveness of the protective device
The protective device can become disabled if the system connection cable is connected
incorrectly.
b
Make sure (e.g. by routing the cables appropriately) that the system connection
cable can only be connected to the system connection of the protective device.
NOTE
Malfunctions can occur if an unused multifunction output (MFP) is wired incorrectly.
b
Unused multifunction outputs must not be connected.
