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:
