UNINTENDED EQUIPMENT OPERATION |
|
Do not exceed any of the rated values specified in the environmental and electrical characteristics tables. |
|
Failure to follow these instructions can result in death, serious injury, or equipment damage. |
NOTE: For important safety information and the environment characteristics of the TMC4 cartridges, see the M241 Logic Controller Hardware Guide.
