Unit Handling Precautions

94
• Always turn OFF the CPU Unit before mounting or removing a Serial
Communications Unit or connecting or disconnecting cables to/from the
Serial Communications Unit.
• Place the port connecting cables in a different duct from those for high-
voltage lines or power lines to prevent the effects of electrical noise from
these lines.
• Do not remove the protective label from the top of the Unit until wiring has
been completed. This label prevents wire strands and other foreign matter
from entering the Unit during wiring. Remove the label after wiring has
been completed to allow air circulation needed for cooling.
• If a serial port is not being used, leave the cover on the port to prevent
dust from entering.
