2 Snap the supervision-master on the 'table' bracket.
3 Fit the supplied flat cable to the connector on the
output board and the supervision-master. Do not
twist the flat cable and fit the polarization pin of the
flat cable in the hole in the PCB next to the
connector.
Proceed as follows to install the supervision-master in
LBB4428/00 Power Amplifiers:

Note
In the spare amplifiers also single line
supervision boards must be installed for those
channels that have single line supervision
boards in the corresponding main amplifier
channels. Otherwise, a Line supervision master
mismatch fault event is generated. Single and
multiple line supervision boards are not
compatible.
