4 INSTALLATION AND WIRING
(4) Be sure to install a power supply module on the main base unit and extension
base unit. Even if the power supply module is not installed, when the I/O modules
and intelligent function module installed on the base units are light load type, the
modules may be operated. In this case, because a voltage becomes unstable, we
cannot guarantee the operation.
(5) When using an extension cable, keep it away from the main circuit cable (high
voltage
and large current).
Keep a distance of 100mm or more from the main circuit.
(6) Be sure to fix a main base unit to the panel using fixing screws. Not doing so could
result in vibration that may cause erroneous operation.
Mount a main base unit in the following procedure.
(a) Fit the two base unit top mounting screws into the enclosure.

(b) Place the right-hand side notch of the base unit onto the right-hand side
screw.

(c) Place the left-hand side pear-shaped hole onto the left-hand side screw.

(d) Fit the mounting screws into the holes at the bottom of the base unit, and
then retighten the all mounting screws.
(Note) : Mount a main base unit to a panel, with no module installed in the right-
end slot.
Remove the base unit after removing the module from the right-end slot.
