7. Place the new driver in the enclosure opening and align its mounting holes with those in the
enclosure. With their lockwashers in place, insert the mounting screws and thread them in
until they are almost tight.
8. If a micro-torque wrench and suitable hex bit is available, tighten the screws to the correct
torque shown in Table 2. Tighten the screws in an alternating criss-cross sequence (Figure 2).
If you don’t have a micro-torque wrench, tighten the screws firmly, but do not overtighten.
9. Re-install the grille on the enclosure. CAUTION: When re-installing the screws, be aware
that the middle hole on the bottom edge of the grille (Figure 3) is for the power LED, not a
screw. Inserting a screw into that hole can damage the LED.
