Sequence Signal Wiring - Allen-Bradley 8720MC-RPS065 User Manual

Sequence Signal Wiring

Sequence output signals are provided from the sequence signal terminal block
(TB3) of the regulator board to indicate the unit status.
Follow these guidelines when installing sequence signal wiring:
• Use twisted pair cable of 0.2...0.5 mm
line.
• Separate the sequence signal wiring from the power wiring (main power
supply wiring, control power wiring, and DC-bus power wiring). Failure
to observe this precaution could result in damage to the 8720MC-RPS
unit.
• Use a separate (dedicated) wireway for the sequence signal wiring.
• Do not route the sequence signal wiring near any equipment that
produces electromagnetic interference.
