1 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 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 HITACHI 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 installation, HITACHI cannot assume responsibility or liability
for actual use based on the examples and diagrams.
Warning!
✓If you don't follow the directions, it could cause a personal injury, damage to the equipment or
explosion
✓Do not assemble the products and wire with power applied to the system. Else it may cause an electric arc,
which can result into unexpected and potentially dangerous action by field devices. Arching is explosion
risk in hazardous locations. Be sure that the area is non-hazardous or remove system power
appropriately before assembling or wiring the modules.
✓Do not touch any terminal blocks or IO modules when system is running. Else it may cause the unit to an
electric shock or malfunction.
✓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.
Caution!
✓If you disobey the instructions, there may be possibility of personal injury, damage to equipment
or explosion. Please follow below Instructions.
✓Check the rated voltage and terminal array before wiring. Avoid the circumstances over 50℃of
temperature. Avoid placing it directly in the sunlight.
✓Avoid the place under circumstances over 85% of humidity.
✓Do not place Modules near by the inflammable material. Else it may cause a fire.
✓Do not permit any vibration approaching it directly.
✓Go through module specification carefully, ensure inputs, Output connections are made with the
specifications. Use standard cables for wiring.
✓Use Product under pollution degree 2 environment.
