Installation precautions :

(1) Because the model 2000 is not of dust-proof construction, install it in a dust-proof
control panel.
(2) Do not install the bases directly above equipment which generates a large amount of
heat, such as a heater, transformer, or large capacity resistor.
(3) Do not install the base in the panel containing high-voltage equipment.
(4) Do not install the bases within 200mm (8in) of a high-voltage or power cable.
(5) Allow at least 70mm on all sides of the base for ventilation.
(6) For safety during operation and maintenance, install the base as far as is
possible from high-voltage or power equipment.
Alternatively, isolate the base using a steel plate or similar separator.
(7) Decide the bases mounting position with considering the length of the expansion
cables.
(8) Install the bases in fully contacting with the mounting frame in order to equalize the
potentials of basic and expansion bases.
(9) In the vicinity of high-voltage and power equipment, it is necessary to give
consideration to grounding.
(10)Install the bases where the power modules are always mounted on the left hand side,
vertically on the mounting frame.
(11)Mount the bases securely, using the base mounting screws of M4 size.
