12 Instructions on laying cables
12.1 General
➔ Don't bend cables while unrolling them. Don't create any loops or twists.
➔ Remember that a strain relief clamp and compression set must be incorporated within the bending
radius.
➔ Don't use extra-long cables and wires (reserve). Avoid mutual interference.
➔ Lay so-called "hot" and "cold" signal lines separately.
For this, use cable ducts in the control cabinet that are physically separated from each other.
Hot signal lines System cable, mains, nutrunner control power supply, cooling unit
Cold signal lines 24 VDC, PE, ARCNet cable, bus cable,
separate cables from transducers
CAUTION!
There is a risk of tripping or falling over loose cables on the ground.
➔ Lay all connected cables safely.
NOTE! ➔ Only cable types approved by Apex Tool Group may be used.
➔ Remember that the maximum total cable length is 50 m.
➔ Take appropriate measures to limit cable bending radii and torsion. Obverse the respective allowed
bending radii and torsional lengths.
➔ All plug connections must be closed. The locks must be tightened. The red ring around the outer diam-
eter of plug connectors with a slide lock should not be visible.
