4. Discharge the outputs of the network bridge at the
contact points against the enclosure using a voltage
detector without intrinsic voltage source and
discharge each of the 6 lower contacts against the
blue contact. When doing so, ensure that the
residual voltage is less than 5 V.
5. Ground yourself prior to replacing the assembly to prevent ESD damage.
6. Remove the screws at the AC connections (TX20 or
TX30). If the bolting block and the terminal lug stick
together, the contact surfaces must be ground prior
to the next connection being made. Ensure that no
grinding filings remain in the device.
7. Clean the contact surfaces on the bolting block and terminal lugs with a suitable cleaning
agent to remove bolt coating deposits.
8. Unplug the connections. When doing so, unlock the
ribbon cable plug first.
