Installing the CU(s) in a rack
Rack requirements for the CU
• EIA standard compatible 19-inch rack
• 1U-size rack mounting
• Rack equipped with safety guardrails to support the CU and a
board on which the CU is to be placed
When installing the CU(s) in a rack, keep the temperature within
the rack below 45°C (113°F). High temperature may damage the
internal components, causing a malfunction.
Leave a space of 10cm or more on each side (top, right and left,
rear) between the CU and other devices or the rack.
Rack mounting angles are fixed to the CU using the following
screws. When using screws other than those listed here, check the
specifications.
• S TIGHT tapping screws with nominal diameter 4×6mm*
* Substitutable for M4×6mm machine screws
Unbalanced connection
Since induction noises tend to occur due to difference in electric
potential of chassis:
• Keep the chassis between each device at the same electric
potential.
• Use the same power system.
• Connect to the GND (ground) terminal or chassis ground of each
device.
AC power cord connection
Be sure to connect the AC power cord into a properly grounded wall
outlet. Improper grounding can cause electrical shock.
When cleaning the units
Do not use any solvents or chemicals such as benzine, thinner,
alcohol or electrical contact cleaner and protector. Doing so may
cause deformation, damage and malfunction of the units.
