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 

Appendix 2.)

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 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.
