CAUTION
1. On January 1, 2003, new United Nations requirements, "United Nations
Dangerous Goods Regulations Article 12", became effective regarding the
transportation of lithium batteries. The lithium batteries are classified as
hazardous materials (Class 9) depending on the unit. (Refer to
"Transportation restrictions for lithium batteries".)
2. The lithium battery must be transported according to the rules set forth by
the International Civil Aviation Organization (ICAO), International Air
Transportation Association (IATA), International Maritime Organization
(IMO), and United States Department of Transportation (DOT), etc. The
packaging methods, correct transportation methods, and special regulations
are specified according to the quantity of lithium alloys. The battery unit
exported from Mitsubishi is packaged in a container (UN approved part)
satisfying the standards set forth in this UN Advisory.
3. To protect the absolute value, do not shut off the servo drive unit control
power supply if the battery voltage becomes low (warning 9F).
4. Contact the Service Center when replacing the MDS-A-BT Series and cell
battery.
5. The battery life (backup time) is greatly affected by the working ambient
temperature. The above data is the theoretical value for when the battery is
used 8 hours a day/240 days a year at an ambient temperature of 25°C.
Generally, if the ambient temperature increases, the backup time and useful
life will both decrease.
