• Always turn OFF the CPU Unit's power supply before connecting or dis-
connecting cables or the Unit itself.
• To minimize the effects of noise, place I/O wiring in a separate duct from
high-voltage lines and power lines.
• Wire strands may be scattered around during wiring, so leave the protec-
tive label on top of the PCU to prevent any wire strands from getting inside
the PCU. Once the wiring has been completed, be sure to remove the
label to allow ventilation.
