Solution 1: Wider cable tray on the front side of the APASolution 2: Temporary cable support installed underneath the front cable tray

Alternative solutions to support cables

Laser asm

Laser asm

Wider cable tray interferences with laser asm.

Current cable tray doesn’t interference with laser asm.

Temporary cable support

Temporary cable supports are attached underneath the cable tray by coupling nuts.

Coupling nuts

Temporary cable supports are removed after cabling completed and will be reused for the next APA cabling.
