IDEC SmartRelay is designed for fixed and enclosed installation in the housing or the control
cabinet.
Safety of electronic control equipment
Introduction
The notes below apply regardless of the type or manufacturer of the electronic control.
Approach for reliability
Maximum reliability of IDEC SmartRelay devices and components is achieved by
implementing extensive and cost-effective measures during development and manufacture.
This includes the following:
• Use of high-quality components
• Design of all circuits for worst-case scenarios
• Systematic and computer-aided testing of all components
• Burn-in of all large-scale integrated circuits (for example, processors and memory)
• Prevention of static charge when handling MOS ICs (Metal Oxide Semiconducor
Integrated Circuits)
• Visual checks at different stages of manufacture
• Continuous heat-run test at elevated ambient temperature over a period of several days
• Careful computer-controlled final testing
• Statistical evaluation of all returned systems and components to enable the immediate
initiation of suitable corrective measures
• Monitoring of major control components, using online tests (cyclic interrupt for the CPU, etc.)
These measures are referred to as basic measures.
WARNING
IDEC SmartRelay is designed for installation in a cabinet. Do not install IDEC SmartRelay
outside a cabinet. If IDEC SmartRelay is installed outside a cabinet, severe personal injury or
death or damage to equipment may be caused due to unexpected operations.
You can operate IDEC SmartRelay from the front panel at any time.
