es:
1) Ground the outer shield of the cable 360 degrees under the grounding clamp on the grounding shelf for
the control cables.
2) Connected with jumpers at the factory.
3) Only frames R6...R11 have terminals 40 and 41 for external 24 V AC/DC input.
Terminal sizes:
1. R1...R5: 24...14 AWG (0.2...2.5 mm
2. 26...16 AWG (0.14...1.5 mm
3. R6...R9: 26...14 AWG (0.14...2.5 mm
4. Tightening torques: 0.4 lb-ft (0.5...0.6 Nm
