It is recommended that you turn on the power in the presence of Yokogawa when turning it on

Post-installation Environment Preservation
The following precautions should be taken to preserve the proper operating environment after the
system has been installed:
• Seal the pits if they are shared by equipment in other rooms, preventing entry of dust and
moisture from the other rooms.
• Seal all cable ducts of equipment and building with putty upon completion of cabling.
• Always turn on air conditioner. Turning it on/off may cause condensation inside equipment.
If you turn on the power of an air conditioner after a long stop, turn on the air conditioner first
and the system. Otherwise condensation may occur.
• Monitor and record the room ambient temperature and humidity. To maintain the reliability of
the equipment, be sure to remove the cause if they fluctuate violently.
• Note that leaving exits and entrances open during installation, or leaving open cable ducts
whiles pulling cables, may result in condensation.
