Operating Environment Precautions

!Caution

Do not operate the Unit in the following places:

• Locations subject to direct sunlight.

• Locations subject to temperatures or humidities outside the range speci-

fied in the specifications.

• Locations subject to condensation as the result of severe changes in tem-

perature.

• Locations subject to corrosive or flammable gases.

• Locations subject to dust (especially iron dust) or salt.

• Locations subject to exposure to water, oil, or chemicals.

• Locations subject to shock or vibration.

Provide proper shielding when installing in the following locations:

• Locations subject to static electricity or other sources of noise.

• Locations subject to strong electromagnetic fields.

• Locations subject to possible exposure to radiation.

• Locations near to power supply lines.

!Caution

The operating environment of the PROFIBUS DP Gateway can have a large
effect on the longevity and reliability of the system. Unsuitable operating envi-
ronments can lead to malfunction, failure and other unforeseeable problems
with the system. Ensure that the operating environment is within the specified
conditions at installation time and remains that way during the life of the sys-
tem. Follow all installation instructions and precautions provided in the opera-
tion manuals.

Application Precautions

Observe the following precautions when using the PROFIBUS DP Gateway.

!WARNING

Failure to abide by the following precautions could lead to serious or possibly
fatal injury. Always heed these precautions.

• Always connect to a class-3 ground (100 

 or less) when installing the

Units.

!Caution

Failure to abide by the following precautions could lead to faulty operation of
the Unit or the system or could damage the Unit or Temperature Controllers
and R88A-MCW151-E. Always heed these precautions.

• Install double safety mechanisms to ensure safety against incorrect sig-

nals that may be produced by broken signal lines or momentary power
interruptions.

• When adding a new device to the network, make sure that the baud rate

is the same as other nodes.
