Safety Precautions
General Warnings
!
WARNING
Do not attempt to disassemble the Unit while power is being supplied. Doing so may
result in electrical shock.
Do not touch any of the terminals while power is being supplied. Doing so may result
in electrical shock.
Take safety measures outside the Cam Positioner to ensure safety for the entire
system in the event of Cam Positioner failure or error caused by external factors of
the Cam Positioner.
Faulty operations may result in serious accidents.
S
Emergency stop circuits, interlock circuits, limit circuits, and similar safety mea-
sures must be included in control circuits outside the Cam Positioner.
S
The Cam Positioner turns OFF all outputs when its self-diagnostic function detects
an error (ERROR is OFF), when TRIG input turns ON, or when RESET input turns
ON. Take safety measures outside the Cam Positioner to ensure safety for the en-
tire system in such an event.
S
The Cam Positioner output may remain ON or OFF due to damage to an output
transistor or for some other reason. Take safety measures outside the Cam Posi-
tioner to ensure safety for the entire system in such an event.

Caution
Fail-safe measures must be taken by the customer to ensure safety in the event of
incorrect, missing, or abnormal signals caused by broken signal lines, momentary
power interruptions, or other causes.
Always use the power supply voltages specified in the operation manuals.
Take appropriate measures to ensure that the specified power with the rated voltage
and frequency is supplied. Be particularly careful in locations where the power sup-
ply is unstable.
Install external breakers and take other safety measures against short-circuiting in
external wiring.
Disconnect the functional ground terminal when performing withstand voltage tests.
Always connect to a ground of 100
Ω
or less when installing the Unit.
Do not attempt to disassemble, repair, or modify the Unit.
Leave the label attached to the Unit when wiring.
Remove the label after the completion of wiring to ensure proper heat dissipation.
Use crimp terminals for wiring. Do not connect bare stranded wires directly to termi-
nals.
Thoroughly check all wiring before turning ON the power supply.
Wire all connections correctly.
Do not place objects on top of the cables or other wiring lines.
Do not pull on the cables or bend the cables beyond their natural limit.
Before touching a Unit, be sure to first touch a grounded metallic object in order to
discharge any static built-up.
Be sure that all the mounting screws, terminal screws, and cable connector screws
are tightened to the torque specified in the operation manual. For DIN track mount-
ing, push the Cam Positioner forward until the lock snaps into place.
