Connecting power to the IDU Chapter 3
WinLink™ 1000 User Manual Release 1.9 3-13
¾ To mount an IDU-C:
1. Attach the rack mounting brackets (K) to the IDU.
2. Bolt the IDU into an empty slot in the rack, ensuring that it sits securely.
3. Ground the IDU to the rack using grounding lug I. The IDU should be left
permanently grounded.
Connecting power to the IDU
The IDU-C has redundant power connection circuits (items G and H in
Figure 3-13 above). An enlarged schematic of the power connectors is
shown in below:
