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:
BUSI 5 and Buass
