Important Notes
• Solid state equipment has operational characteristics differing from those of electromechanical
equipment.
• Safety Guidelines for the Application, Installation and Maintenance of Solid-State Controls
describes some important differences between solid state equipment and hard-wired
electromechanical devices.
• Because of this difference, and also because of the wide variety of uses for solid state
equipment, all persons responsible for applying this equipment must satisfy themselves that
each intended application of this equipment is acceptable.
• In no event will Beijer Electronics be responsible or liable for indirect or consequential
damages resulting from the use or application of this equipment.
• The examples and diagrams in this manual are included solely for illustrative purposes.
Because of the many variables and requirements associated with any particular installation,
Beijer Electronics cannot assume responsibility or liability for actual use based on the
examples and diagrams.
✓ A Caution symbol indicates a potentially hazardous situation which, if not avoided, may
result in minor or moderate injury and or damage to the device.
Read the following Instructions:
•Keep vibrations away from it.
•Products should be used in environments with a pollution index of less than 2.
•Ensure that the installation environment does not exceed 85% humidity.

JetNet 3905 Series Installation Guide
✓ A Warning symbol indicates a hazardous situation which, if not avoided, could result in
damage to the device, death or serious injury.
Read the following Instructions:
•In order to prevent electric arcs, never assemble or wire the products with power applied.
Otherwise, it may result in unexpected and potentially dangerous actions by field devices.
Arching poses an explosion risk in hazardous locations. Before assembling or wiring the
modules, ensure that the area is non-hazardous or that the system power has been removed
accordingly.
•Check the rated voltage and terminal array before wiring. Avoid environments over 50℃of
temperature. Avoid placing it directly in the sunlight.
•Ensure that inputs and outputs are made according to the module specification. Wire the
system using standard cables.
•In order to avoid an electric shock or malfunction, do not touch any terminal blocks or IO
modules while the system is running.
•Keep away from the strange metallic materials not related to the unit and wiring works
should be controlled by the electric expert engineer. Else it may cause the unit to a fire,
electric shock or malfunction.
•Modules should not be placed near inflammable materials. A fire may result if it is not
handled properly.
