Electrical installation
Prevent the occurrence of a potential difference between the load and the protective
d
evice!
If you connect loads that are not reverse-polarity protected to the OSSDs or the safety
outputs, you must connect the 0 V connections of these loads and those of the
corresponding protective device individually and directly to the same 0 V terminal strip.
This is the only way to ensure that, in the event of a defect, there can be no potential
difference between the 0 V connections of the loads and those of the corresponding
protective device.
Route all cables and connection cables such that they are protected from damage.
If you use the S3000 for the protection of hazardous areas: Ensure that also the
controller connected and all devices related to safety have the required category as per
EN ISO 13849-1 or the required performance level as per EN ISO 13849!
If you use screened cables, lay the screen evenly around the cable gland.
Ensure that the S3000 is adequately protected electrically. You will find the electrical
data necessary for determining the correct fuse in section 12.4 “Data sheet” on
page 147.
