INSTALLATION

4.3.2Clearance

The printed circuit board (PCB) is designed to be very close to the mounting holes. Do not exceed the specified length for the mounting screw described in Figure 4-3. The specified screw length allows full use of the mounting-hole threads, while avoiding damage or placing unwanted stress on the PCB.

Figure 4-3: Mounting-Screw Clearance

CAUTION: Using mounting screws that are longer than the maximum lengths specified in Figure 4-3 voids the warranty of the drive.
