1. In order to reach the instruments which are above the Grid Floor A ,see F1 above, cables coming from the Branch Tray C have to pass the Grid Floor A.
1 l: r8 C, w4 a& ?! t/ M1 U2. If using basket tray to conduct cables, you have to make a hole at the Grid Floor A by cutting a piece of stuff from the Grid Floor A. then the basket trays can go through the Grid Floor A.
2 I! ?1 L9 G0 i3 _6 A/ \4 P3. IF using a pipe to conduct cables, because the size of the pip is one inch you can make a small hole at the Grid Floor A by a iron bar(撬棍) ) W$ x8 d9 Z2 g2 B/ @" f; J
4. While you finish one hole for the tray, you can finish 10 holes for the pipe with the same time.
1 w0 A5 m# v7 X, l$ G So to make job easy and fast I prefer to use more pipes.
! ]3 h+ |3 A6 V/ O As shown on F2, see the Ins A. If x or y is >18 inches I cut a hole for the tray.
3 K! T0 i! Q, H The distance of 18 inches is mandatory by SHELL.# w1 L6 x/ ~6 }8 ~1 A: y2 f
In this case about 85% instruments above the Grid Floor A have been serviced by pipes. |
