service personnel. The service personnel are defined as experienced technicians who have been sufficiently
educated and trained, and are capable of perceiving and avoiding operational hazard.

5. Disposal of batteries
When disposing of batteries, separate them from other wastes according to the local regulations. (For details of the
battery directive in EU member states, refer to the user’s manual for the CPU module used.)

6. Transportation precautions
As they include lithium, the Q7BAT-SET and Q7BAT must be treated as Class 9 dangerous goods during
transportation. Prior to shipment, Mitsubishi packs products properly in order to ensure safety. However, when
transporting the products, which are unpacked once or repacked after purchase, make sure to observe the
dangerous goods regulations of the country as well as IATA Dangerous Goods Regulations and IMDG code. Also,
consult and determine the details with the transportation company.
