4.1 Installation and Wiring of Optical Shared Hub Unit
The TC-net 100 optical transmission line uses optical shared hub units to connect TC-net
100 nodes. Fasten the optical shared hub units to the cabinet.
Observe the allowable cable bending radius requirements and clamp the cables after
wiring.
There are three ways of fastening the optical shared hub unit as shown in figure 4-1. M4
screws are used for it.
(1) Back mounting
Fasten two panel mounting L-brackets to the rear of the optical shared hub unit with
eight M3x6 screws on both sides, and fasten the unit to a rear support panel with four
M4x6 screws.
(2) Front mounting
Fasten two panel mounting L-brackets to the front of the optical shared hub unit with
eight M3x6 screws on both sides, and fasten the unit to a front support panel with
four M4x6 screws.
(3) Bottom mounting
Fasten four panel mounting L-brackets to the front and back of the optical shared hub
unit with 16 M3x6 screws on both sides, and fasten the unit to a bottom support panel
with eight M4x6 screws. Remove the four rubber feet.
If the cabinet is not exclusively grounded to the Integrated Controller, insulate the hub
from the cabinet.
