Optical Fibers - ABB ACS5000 User Manual

6.5.1. Optical fibers

NOTICE
Handle optical fibers with care. A damaged or incorrectly installed optical
fiber cable can degrade data transmission and cause equipment failure.
– Only use the designated encoder cable conduit that passes through
the drive to the EXU.
The conduit extends 10 – 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.
– When you tighten the cable ties DO NOT deform the optical fibers and
DO NOT use a cable tie gun.
– Hold the connector when you connect or disconnect an optical fiber.
Optical fibers for internal arc protection
NOTICE
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. 3-15) 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.
