11.3 Installation
11.3.1 Supervision-master
Proceed as follows to install the supervision-master in
PRS-xPxxx Power Amplifiers:
1 Remove the lid from the power amplifier and locate
the output board (see figure 11.4).
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:
1 Remove the lid from the power amplifier and locate
the output board (see figure 11.4).
2 Remove the screws of the bracket and slide it out of
the holes in the output board.
3 Fit the supervision-master on the ‘slide’ bracket.
4 Slide the supervision-master and bracket assembly in
the holes in the output board.
5 Tighten the screw to fix the supervision-master and
bracket assembly to the output board.
6 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.
Warning
To prevent the hazard of electric shocks,
disconnect the mains cord and the back-up
power supplies from the power amplifier before
starting installing the supervision-master.
Warning
The electronics inside the power amplifier and
on the supervision-master are susceptible to
electrostatic discharges. Wear an anti-ESD
bracelet during the installation of the
supervision-master.
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.
