General Installation Recommendations
Installation
Computer Upgrade Precaution Note
Users who needs to open the computer to change PCI cards, install more memory, or set internal jumpers can do so
without voiding the warranty. Before opening a unit’s housing to remove or touch a board, proper ESD measurements
must be taken!
1. Operator should ground himself by using a wrist band.
2. The wrist band should be connected to ground via a ground cord.
3. A one megaohm resistor, installed in the wrist connection end of the ground cord, is a safety requirement.
4. Hatteland recommend to use an Static-dissipative ESD work mat positioned at the workplace. The 3M™ 8501
Portable Field Service Kit is a good choice for this purpose. Make sure that the mat, operator and product is wired/
grounded together.
All assisting persons who might come into contact with the endangered boards must also use the ESD equipment.
