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.
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
• Worst-case design of all circuits
• Systematic and computer-aided testing of all
components
• Burn-in of all large-scale integrated circuits (e.g.
processors, memory, etc.)
• Measures preventing static charge when handling MOS
ICs
• 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.)
!
Warning
Death, serious bodily injury or considerable damage to property
can occur.
Modules of an IDEC SmartRelay are open facilities. This means
that you must install IDEC SmartRelay only in a housing or cabinet.
Allow access to the housings or cabinets only with the use of a key
or a tool and only allow access to authorized or approved
personnel.
It is permissible to operate IDEC SmartRelay from the front at any
