Move the yellow sliders on the top and bottom of the Unit until they click into position, to lock.
Precautions for Safe Use
If the sliders are not securely locked, the PROFIBUS Slave Unit may not operate sufficiently.
To dismount the Unit, move the sliders to the “Release” direction.
•
Always turn OFF the power supply to the Controller before you mount or dismount a Unit or con-
nect or disconnect cables.
•
Provide separate conduits or ducts for the I/O lines to prevent noise from high-tension lines or
power lines.
•
Prevent wire clippings, cutting chips or other materials from getting inside the Unit. They could
cause scorching, failure and malfunction. Pay particular attention to this during installation and
take measures such as covering the unit.
If the Unit was shipped from the factory with the dust protection label on top of the unit, be sure to
remove that label before switching ON the power. The label prevents heat dissipation and could cause
a malfunction.
