circuits.
The control unit is an extension of the modular MODIOS I/O system and can be installed in
an existing I/O module box system.
This control unit has been designed and produced in accordance with a variety of interna-
tional safety standards. There is no potential danger from the control unit when used for its
intended purpose.
To maintain the control unit in a safe condition, it is sufficient to observe some simple, widely
known rules of behavior.
To ensure optimal operation of the control unit, only appropriately trained and skilled per-

Please observe the following safety recommendations:
Do not attempt to make internal adjustments or replacements except as directed in this
User's Handbook.
Do not operate the control unit with any covers or parts removed.
To the extent possible, disconnect the control unit from all voltage sources before open-
