Safety Precautions
1. Safety Precautions for Installation
WARNING
Grounding required:
Ground the transmission path at each segment with 100Ω or less ground resistance.
Grounding should be made at one point.
Otherwise，this can cause a transmission error or this can result in electric shock or fire.
Prohibit excessive voltage:
Do not apply voltages higher than the rated voltage (such as 100VAC) to connectors or terminal blocks or do
not mistake the polarity of voltages.
CAUTION
Choose proper environment for installation:
Avoid installing and storing the equipment in the following environments:
 Location with considerable dust
 Location in which flammable or corrosive gases (such as SO2 and H2S) are present
 Location where vibration or shock exceeds allowable limits
 Location where condensation may occur due to rapid change in temperature
 Location where the temperature is not within the specified range for installation
 Location where the humidity exceeds the specified limits for installation
 Location in the direct sunlight
 Location near a device that generates strong radio waves or magnetic fields
Considerations for maintenance and inspection:
Install the equipment in a place that facilitates maintenance and inspection. If not, in case of malfunctioning, it
may hinder the recovery of the system and result in serious accident.
Ensure proper ventilation:
Do not block vents, intake or exhaust openings of the equipment. Blocking them may cause mulfunctioning or
overheating which may result in fire.
Check specifications:
Follow the installation conditions written in this manual when mounting and wiring the system.
Otherwise，the original performance cannot be achieved，and it may cause the malfunction or system failure.
Turn off power before installing modules:
Turn off the power before installing modules. Otherwise，it may result in electric shock or module failure.
Emergency stop circuit and interlock circuit:
Construct the emergency stop circuit and interlock circuit outside the equipment.
Otherwise, it may cause an injury accident or damage to the machine if failure or malfunction occurs in the
equipment.
