NOTICE
Risk of equipment failure!
• Handle optical fibers with care.
- DO NOT touch the ends of the fibers, they are sensitive to dirt.
- When unplugging, hold the connector and not the fiber.
- If an optical fiber is damaged or improperly installed, data
transmission can be affected and the equipment can fail.
- To prevent such problems, follow the handling and
installation guidelines.
• Observe the maximum long-term tensile load of 1 .0 N and the
minimum bend radius of 2 5 mm .

supply cable
(2) Cable tray for control cables
(3) Cable duct for optical fibers
2. Lay the cables into their designated trays and cable ducts as
illustrated in Fig. 6-5.
Note: When fastening IGCT power supply cables on the rail for IGCT
power supply cables of RBU, BCU and VLU, make sure that the cables
