General Torque Values for Screws
Use a Phillips PH1 screw driver for screws of the G500. Unless otherwise specified, use the
following torque values when tightening screws:
Screws with Torx head are not for service and shall not be unscrewed.
Storage recommendations
Storage conditions
Always store the G500 in an environment compatible with operating conditions.
Recommended environmental conditions for storage are:
•Temperature: 40°C to +85°C
• Relative humidity: 5% to 95%, non-condensing
Exposure to excessive temperature or other extreme environmental conditions might
cause damage and/or unreliable operation.
To avoid deterioration and early failure of electrolytic capacitors, power up units that are
stored in a de-energized state once every 12 months, for one hour continuously.
