Optical Fibers; Optical Fibers For Internal Arc Protection - ABB ACS5000 User Manual

6.5.1. Optical fibers

NOTICE
Risk of equipment failure! A damaged or incorrectly installed optical fiber cable can degrade
data transmission and cause equipment failure.
→ Handle optical fibers with care.
→ Only use the designated encoder cable conduit that passes through the drive to the EXU; The
conduit extends 10 to 20 mm from the entry plate of the drive.
→ Cover the cable end with a cap BEFORE you pull the cable through the conduit.
→ DO NOT exceed the maximum tensile load of 1.0 N and the minimum bend radius of 25 mm.
→ DO NOT deform the optical fibers when you tighten the cable ties and DO NOT use a cable
tie gun.
→ Hold the connector when you connect or disconnect an optical fiber.

6.5.1.1. Optical fibers for internal arc protection

NOTICE
Risk of cable damage. Optical fiber cables are only available in standard lengths.
→ DO NOT cut or extend the cables
→ Wind up excess cable in coils with a minimum diameter of 100 mm.
Each unit with power cable entries and terminals is monitored for arc faults by the Arc Guard
System™ with up to 4 detectors. See the project-specific "Converter hardware diagram" on
page 392 for the exact number of detectors in each cubicle.
The Arc Guard unit and the HMI panel are in the COU (Fig. 19) and the detectors are pre-installed
in the relevant cabinets. The optical fibers, which are coiled up beside the detectors, must be
routed from the detectors to the Arc Guard unit in the COU.
