When setting up the system, do not allow any empty slot on the base unit.
DANGER
If any slot is left empty, be sure to use a blank cover (A1SG60) or a dummy module
(A1SG62) for it.
When using the extension base unit, A1S52B(S1), A1S55B(S1), A1S58B(S1), attach
the included dustproof cover to the module in slot 0.
Otherwise, internal parts of the module may be flied in the short circuit test or when an
overcurrent or overvoltage is accidentally applied to the external I/O section.
When A1S52B(S1), A1S55B(S1), A1S58B(S1) is used, it is necessary to install the
dustproof cover, which is supplied with base to the I/O module to be installed to the left end
in order to prevent intrusion of foreign material into the I/O module. Intrusion of foreign
matter into the I/O module may cause breakdowns. Procedures for installing and removing
the dustproof cover are described below.
