Altitude Operating Conditions
The characteristics in the table below apply to the modules BMX DDI 6402K and BMX DDI 6402KH for use at altitude up to 2000 m (6560 ft). When the modules operate above 2000 m (6560 ft), apply additional derating.
For detailed information, refer to chapter Operating and Storage Conditions.
