Mitsubishi Electric MELIPC MI5000 Series User Manual page 4

[Design Precautions]
CAUTION
● Do not install the control lines or communication cables together with the main circuit lines or power
cables. Keep a distance of 100 mm or more between them. Failure to do so may result in malfunction
due to noise.
● When selecting fuses and breakers for external circuits, consider the specification values of fusing/
detection characteristics and inrush current.
● When using an uninterruptible power supply (UPS), do not use the one that outputs square waves.
[Installation Precautions]
CAUTION
● Use the product in an environment that meets the general specifications described in MELIPC MI5000
Series User's Manual (Startup). Failure to do so may result in electric shock, fire, malfunction, or
damage to or deterioration of the product.
● To mount a power supply module, place the concave parts located at the bottom onto the guides of
the main module, and push in the power supply module until the hooks located at the top snaps into
place. Incorrect interconnection may cause malfunction, failure, or drop of the module.
● When using the product in an environment of frequent vibrations, fix the power supply module with a
screw.
● Tighten the screws within the specified torque range. Undertightening can cause drop of the screw,
short circuit, or malfunction. Overtightening can damage the screw and/or module, resulting in drop,
short circuit, or malfunction.
● To connect a fan module, set the fan module at the correct position of the main module, and push in
the fan module until the fan module fixing hook snaps into place. Check that the fan module fixing
hook is fixed to the main module securely. If the fan module is not connected properly, the fan may not
rotate or it may cause malfunction due to rise in temperature of the main module.
● To disconnect a fan module, securely press the fan module fixing hook with your finger. Then, pull the
module forward while pressing the hook.
● Do not touch the exposed heatsink after removing the fan module. The heatsink is very hot
immediately after the power is switched off and may cause burns. Additionally, touching the heat sink
may deform it and decrease cooling efficiency.
● Do not apply shock such as falling and dropping to the fan module during transportation. Doing so
may result in damage to the product or deterioration in performance.
● When using a CFast card, fully insert it into the CFast card slot. Check that it is inserted completely.
Poor contact may cause malfunction.
● Place hands to hold a CFast card when removing it from the slot because the card may be jumped
out. If not placing hands, the card may fall, resulting in damage or failure.
● Do not directly touch any conductive parts and electronic components of the module or CFast card.
Doing so can cause malfunction or failure of the module.
● Do not remove the protective sheets attached to the plate of the base part. The plate of the base part
also acts as a heat sink and may be very hot during operation. To prevent a burn, do not remove these
sheets or touch them during operation or immediately after the power supply is switched off.
