Preventive Maintenance
WARNING! Before performing any maintenance, the chapter Safety Instructions at the
beginning of this manual must be followed. Negligence of these instructions can
cause injury or death.
WARNING! The printed circuit boards contain components sensitive to electrostatic
discharge. Use an ESD-field service kit when handling the boards. Do not touch the boards
unnecessarily.
Handling the boards:
When ESD sensitive boards are removed from the drive and transferred to a temporary
work surface, they should be placed in a protective packaging.
Handle unprotected ESD sensitive boards only when connected to the system and always
place them in a protective package that is sealed.
It is easiest to use the spare parts ESD package. Place the protective package on the ESD
mat before opening.
