7.4.1 Screwing
Four screws should be tightened equally with 0.3 N.m ( 3 kgf.cm ) torque. The depth should be 3.0 mm min. and 3.5 mm maximum.
7.4.2 Installation
①The drive should be mounted carefully on the surface of 0.1mm or less flatness to avoid excessive distortion.
②In order to prevent
③Enough space should be kept around the drive especially around the convex portion of HDA (See fig. 2) to
avoid any contact with other parts, which may be caused by receiving shock or vibration.
④The temperature of the top cover and the base must always be kept under 60℃ to maintain the required reliability. ( If the drive runs continuously or
adequate ventilation is available to keep the temperature of top cover under 60℃)
⑤M3 mounting screw holes are tapped directly on the base for electrical grounding between the drive and the
base. In order to prevent the drive performance from being affected by the system noise, appropriate evaluation should be conducted before deciding loading method.
⑥Be sure not to cover the breathing hole ( See fig. 1) to keep the pressure inside the drive at a certain level.
⑦Don’t apply any force to the top cover except to the screw areas ( See fig. 2) on top cover. The maximum force to the specified area is 2N.
⑧The drive contains several parts which may be easily damaged by ESD(Electric Static Discharge). Avoid touching the interface connector pins and the surface of PCB. Be sure to use ESD proof wrist strap when handling the drive.
⑨A rattle heard when the drive is moved is not a sign of failure.
