CAUTION
When removing a module, remove the module fixing screws before attempting to remove the
lugs from module fixing holes. Forcing out a module may damage the lugs.
Turn off the power supply before mounting or removing a module.
The terminal block and pin connectors of this base unit are made of resin. Do not drop them or
give them hard impact.
Do not remove the printed circuit boards of each module. Doing so can cause a failure.
Wire the cables carefully to ensure that no foreign matter such as wire-offcuts enter from the
module top. Remove them if any.
Tighten the module mounting and emergency stop input terminal screws within the tightening
torque ranges.
When fitting the module to the base, press the module against the base to ensure that the latch
is locked into the base. When removing the module, push the latch until the latch comes out of
the base completely, and pull the module toward you.
