4.2 Installing the unit
The T1-16S basic unit and the I/O module come equipped with a bracket at the rear
for mounting on a 35mm DIN rail.
Installation precautions:
• Because the T1-16S is not dust-proof, install it in a dust-proof enclosure.
• Do not i nstall the unit directly above equipment that generates a large amount of
heat, such as a heater, transformer, or large-capacity resistor.
• Do no t install the unit within 200mm of high-voltage or high-power cables.
• Allow at lea st 70mm on all sides of the unit for ventilation.
• For safely during maintenance and operation, install the unit as far as possible from
high-voltage or power equipment. Alternatively, keep the unit separate using a
metal plate or similar separator.
• If high-frequency equipment is installed in the enclosure together with the T1-16S,
special attention is required for grounding. See section 4.4.
• Be sure to in stall the unit vertically with keeping the power terminals downside. Do
not install the unit horizontally or upside-down for safety reason.
• Use M4 size screws to mount the T1-16S.
