Installing units
Installation precautions:
Because the T3 is not dust-proof, install it in a dust-proof
enclosure.
Do not install the unit directly above equipment that generates a
large amount of heat, such as a heater, transformer, or large-
capacity resistor.
Do not install the unit within 200 mm (8 in) of a high-voltage or
power cable.
Allow at least 100 mm distance (4 in) on all sides of the unit for
ventilation.
For safety during operation and maintenance, install the unit as
far as is possible from high-voltage or power equipment.
Alternatively, isolate the unit using a steel plate or
similar separator.
If the unit is installed on a horizontal panel, ambient
temperature should be less than 40’ C.
Decide the units mounting position with considering the length of
the expansion cables.
Install the units in fully contacting with the mounting frame in
order to equalize the potentials of basic and expansion units.
The unit mounting dimensions are as follows:
