502A Array Procedures

Note: Refer to Figure 9 for the following
procedures.
1. Grille Removal
1.1 Remove the 2 screws (2) located on
each end of the grille (1) using a 7/64" hex
wrench. Grasp the grille on both ends and
pull it away from the array.
2. Driver Removal
2.1 Perform procedure 1.
2.2 Remove the 3 screws (6) that secure the
driver (5) to the array.
2.3 Lift the driver carefully away from the
array. Make a note of the wiring configura-
tion and cut the wires connected to the driver
terminals as close to the terminals as pos-
sible.
Re-assembly Notes:
1. Be sure to observe polarity when connect-
ing the replacement driver. Refer to the
wiring diagram, Figure 10.
2. Be sure that the driver gasket is properly
aligned so that it makes an airtight seal.
3. Passive Component Removal
3.1 Perform procedure 1.
3.2 Remove the 2 drivers located on the end
of the array opposite the serial number (refer
to procedure 2 above), but do not cut any
wires.
3.3 Resistor (8) or capacitor (9) removal:
Unwrap the component's leads from its
wirewrap terminal (11), and remove the
component from the array.
3.4 Inductor (12) removal: Remove the
screw (6) and washer (13) that secure the
inductor to the array. Cut the inductor leads
