NOTE: THE FOLLOWING PROCEDURES MUST BE FOLLOWED
WHEN INSTALLING NEW S53AMI/S64AMI AMP MODULES:
FAILURE TO FOLLOW ONE OR MORE OF THESE STEPS MAY
RESULT IN THE INSTANT DESTRUCTION OF THE MODULE WHEN
POWERED UP.
Align white indent marker on Amp Module with indent marker on main
PCB; alternately observe position of label on the top of the module;
incorrectly replacing the Module 180 in the PCB slot will result in its
destruction.
All AC powered test instruments (meters, oscilloscopes, etc.) must
have a floating ground, i.e. be connected to an isolation transformer.
Align and position the Amp Module before soldering.
Attach the amp Module with the mounting screws or
powering up.
Use only rosin-core or non-acid core solder; thoroughly de-flux the
surfaces after soldering.
If the new S53AMI/S64AMI Amp Module has larger mounting hole(s) in
the case, and the stock screws no longer will fit, and screws of the
proper type cannot be obtained locally order:
(2) part# 60301S (screws)
(2) part# 60301N (nuts)
