Installing The A2CCPU
This section gives conditions for installing the A2C to a panel.
(1) To provide good ventilation and to make module replacement easy,
allow a clearance of 80 mm (3.11 in) or more between the top side of
the module and surrounding structures or parts. (See Fig. 6.1.)
(2)
If the A2C I/O module, A66PC or other module is to be installed on the
left side of the A2C, provide a clearance of 10 mm (0.39 in) or more
between them to allow Cover 1 to be opened and closed.
(3)
Mount the module on a separate panel or away from large electromag-
netic contactors and no-fuse circuit breakers which produce vibrations.
(4) To avoid influence of noise or heat radlatlon, allow a clearance of 100
mm (3.94 in) or more if the A2C faces such noise or heat radiating
devices (when such devices are mounted on the back side of the door).
(See Fig. 6.2.) Also, allow a clearance of 50 mm (1.97 in) or more
between the side face of the A2C, A2C I/O or other modules and
devices.
