Environmental considerations
These are the temperature and humidity requirements:
v Operating: +5°C to 40°C (41° to 104°F) with 8% to 80% relative humidity
v Shipping: −40°C to +60°C (−40° to 140° F), which includes condensation but not
rain
v Storage: 0°C to +60°C (32° to 140° F)
A fan contained in the power supply provides forced-air cooling. All the vents on the
front and rear of the 4810/4910 must have 51 mm (2 in.) minimum clearance.
The 4810/4910 SurePOS 300 meets applicable worldwide Electromagnetic
Compatibility (EMC) standards. Refer to Appendix C, “Notices,” on page 57 for a
complete description.
