Post-installation inspection

Upon the completion of installation of instrumentation, before turning on the power inspect the 

following items in the list below to avoid system contamination by dust and moisture dust and 

condensation.

Table  Inspection before power on

Inspection items (daily inspection/maintenance items) 

Environment 

No water intrusion from cable ducts. 

No wind/rain blow-in 

Enclosure bottoms covered to prevent entry of wind, dust, moisture

Enclosures and surroundings cleaned

No dust entering

Free of salty, ferrous, corrosive gas

No direct sunlight on equipment

Equipment 

No condensation or traces on enclosure interior/exterior

No discoloration or rust on enclosure interior/exterior

No condensation or traces on cards (disconnect cards on the upper, middle, and lower 

stands, and left and right sides of the enclosure to check that there is no condensation on 

the cards or defects anywhere in the enclosure.)

No dust remaining inside cabinet 

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

first.

Post-installation environment preservation

The following precautions should be taken to preserve the proper operating environment after the 

system has been installed:

•  Monitor and record ambient temperature and humidity. To maintain the reliability of the 

equipment be sure to remove the cause if they fluctuate violently.

•  Note that leaving the door of the enclosure open during installation, or leaving open cable 

ducts whiles pulling cables, may result in condensation.
