Installation
Follow these rules when installing the GRT1-ML2:
•
Before installing the GRT1-ML2 or connect or disconnect cables, switch
off the power of the Trajexia system, the SmartSlice I/O Units and the
external I/Os.
•
Make sure that the power supplies of the GRT1-ML2, the SmartSlice I/O
Units and the external I/Os are correctly connected.
•
Provide separate conduits or ducts for the I/O lines to prevent noise from
high-tension lines or power lines.
•
It is possible to connect up to 64 SmartSlice I/O Units to 1 GRT1-ML2.
•
Install the GRT1-ML2 and the SmartSlice I/O Units on a DIN rail. To
install a GRT1-ML2 on the DIN rail, press it onto the DIN track from the
front, and press the unit firmly until it clicks. Check that all DIN rail sliders
of the unit are locked onto the DIN rail.
•
To remove the GRT1-ML2 from the DIN rail, release the sliders from the
DIN rail with a screwdriver, and pull the unit straight from the DIN rail.
