NOTE
1 Units need to be spaced at least 32 mm apart, in which case
a flat cable of about 20 mm in length is required. To install
units further away from each other, the cable length will be
20 mm plus the extra distance. Note that the maximum
length of a flat cable is 100 mm.
2 To ensure adequate ventilation, install the units in such a
way that the flat cables lie on top of them. The basic unit is
provided with a heat radiation hole on the upper side (area
indicated using the dotted line in the above figure). When
installing a flat cable, be careful not to block the hole with the
cable. In other words, an expansion unit should be placed
for such a direction that the flat cable of the expansion unit
will not block the heat radiation hole of the basic unit, as
shown above. To be specific, when a connector panel
printedcircuit board is connected directly, the expansion
unit shall be placed on the righthand side of the basic unit
as viewed when you face the mounting surface. If the DIN
rail or screws are used to mount the expansion unit, it shall
be placed on the lefthand side.
