ATTENTION
!
• Do not use the Bulletin 900 Controller in the following
places which might exceed its specifications:
– Places subject to dust or corrosive gases (in
particular, sulfide gas, and ammonia gas)
– Places subject to high humidity, condensation, or
freezing
– Places subject to direct sunlight
– Places subject to vibration and large shocks
– Places subject to splashing liquid or oily atmosphere
– Places directly subject to heat radiated from heating
equipment
– Places subject to intense temperature changes
• To allow heat to escape, do not block the area around
the Bulletin 900 Controller. Ensure that enough space
is left for the heat to escape. Do not block the
ventilation holes on the casing.
• Cleaning: Do not use paint thinner or the equivalent.
Use standard grade alcohol to clean the Bulletin 900
Controller.
• Use within the following temperature and humidity
ranges:
Temperature: –10…+55
°C
Humidity: 25…85% (with no icing or condensation)
If the Bulletin 900 Controller is installed inside a
control panel, the ambient temperature must be kept to
under 55
°C, including the temperature around the
controller.
If the Bulletin 900 Controller is subjected to heat
radiation, use a fan to cool the surface of the controller
to under 55
°C.
• Never place heavy objects on, or apply pressure to the
Bulletin 900 Controller as it may cause it to deform and
deteriorate during use or storage.
