Altitude Operating Conditions

The characteristics in the table below apply to the modules BMX DDI 1602 and BMX DDI 1602H 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.
