!WARNING
Failure to abide by the following precautions could lead to serious or possibly
fatal injury. Always heed these precautions.
• Always ground the system to 100
Ω
or less when installing the system to
protect against electrical shock.
• Always turn OFF the power supply to the system before attempting any of
the following. Performing any of the following with the power supply turned
ON may lead to electrical shock:
• Mounting or removing any Units (e.g., Power Supply Unit, I/O Units,
CPU Unit, etc.) or memory cassettes.

Units.
• Take measures to stabilize the power supply to conform to the rated sup-
ply if it is not stable.
• Provide circuit breakers and other safety measures to provide protection
against shorts in external wiring.
• Do not apply voltages exceeding the rated input voltage to Input Units.
The Input Units may be destroyed.
• Do not apply voltages exceeding the maximum switching capacity to Out-
put Units. The Output Units may be destroyed.
• Always disconnect the LG terminal when performing withstand voltage
tests.
• Install all Units according to instructions in the operation manuals.
Improper installation may cause faulty operation.
• Be sure to tighten Backplane screws, terminal screws, and cable connec-
