Important Safety Information
Before using the Multiple Installation Controller(*) (Pressure Controller MP1-200/MI Terminal MT1-200),
ensure that this operation manual is read and fully understood; furthermore, the instructions given herein
should be strictly observed during operation.
The Multiple Installation Controller(*) contains high voltage sections that could cause electric shock.
Failure to use the controller in the appropriate manner can, therefore, result in death, injury, the outbreak
of fire, and other serious accidents.
In order to ensure that tasks undertaken during operation and maintenance of the Multiple Installation
Controller(*) can be completed safely, it is critical that all dangerous and hazardous parts of this
equipment be confirmed in advance. Here at MIURA, it is practically impossible to anticipate all
potentially dangerous situations, and therefore, this operation manual deal only with known hazards. A
higher level of safety can be achieved by carefully observing the warnings and instructions set forth
herein.
Safety- and damage-related warnings are classified into the following three levels, and notification of
these warnings is provided within this operation manual and using warning labels(*) on the Multiple
Installation Controller(*) itself.
Indicates an imminently dangerous situation which leads to serious injury or
death to the user, if the product is mishandled.
Indicates a situation which might cause serious injury or death to the user, if
the product is mishandled.
Indicates a situation which might cause minor injury to the user or the
occurrence of physical damage only, if the product is mishandled.
If any part used in the product fails, contact our sales office to replace it with its genuine part. Using parts
of different models might reduce safety.
It should be noted that unauthorized alteration of the Multiple Installation Controller (*) or repair
procedures other than those described herein can pose a serious safety risk. Never make any
modifications or repairs without MIURA’s permission.
