====== Safety and Installation Precautions ======

Because ILOGICS products are used in industrial equipment, safe operation requires consideration of power, wiring, protective circuits, and risk assessment of the entire machine, as well as correct program operation.

===== Essential Rules =====

  * Turn off the power before wiring, connecting modules, or changing DIP switches.
  * Distinguish supply voltage, input voltage, load voltage, current per point, and total COM current.
  * Do not infer electrical ratings from other models when they are not specified in the product manual.
  * Provide separate back-EMF and inrush-current protection for inductive loads.
  * Implement emergency stops, overcurrent protection, interlocks, and any required redundant safety circuits independently of the MCU.
  * Design the circuit and program so the equipment enters a safe state when outputs are OFF.

===== Relay and Transistor Outputs =====

The relay contact component's maximum rating is not a product rating valid for every load. Transistor outputs use an N-CH FET SINK configuration and require an external load supply and COM wiring.

===== Analog Signals =====

Confusing the DIP-switch settings or wiring for voltage and current inputs can damage the product and connected equipment. Before connecting a signal, verify its actual type and range with a multimeter.

===== Unspecified Items =====

Ask ILOGICS about any explosion protection, ingress-protection rating, dielectric strength, operating temperature/humidity, certification, wire size, or tightening torque not specified in the current product documentation.
