Mounting the Isolated Barriers on the Termination Board to Ensure
Vibration Resistance
Following the instructions below will ensure that the isolated barriers and the termination board
are mounted in a manner that ensures vibration resistance in line with
IACS Unified Requirements E10.
1.
Mount the termination board as described in the previous section. Make sure that the back
of the device is flush with the mounting base.
2.
Mount the isolated barriers as described in the previous section.
3.
Mount the isolated barriers (1) side by side on the termination board. Ensure that all slots
are occupied.
4.
Fix eight isolated barriers using four cable ties (2) level with the grip (4).
5.
Ensure that the cable tie ratchets (3) are positioned at the corners. We recommend
this arrangement as the cable ties are difficult to bend.
6.
Pull the cable ties (2) tight. Ensure a secure fit.
