z
SafetyOne is designed for installation within an enclosure. Do not install SafetyOne outside an
enclosure. Install SafetyOne in enclosure rated IP54 or higher.
z
Install SafetyOne in environments described in the catalog, instruction sheet, and user’s manual.
If SafetyOne is used in places where it is subjected to high temperature, high humidity,
condensation, corrosive gases, excessive vibrations, and excessive shocks then electrical shocks,
fire hazard, or malfunction may result.
z
Environment for using the SafetyOne is “Pollution degree 2”. Use SafetyOne in environments of
pollution degree 2 (according to IEC/EN60664-1).
z
Prevent SafetyOne from falling while moving or transporting otherwise damage or malfunction of
the SafetyOne may result.
z
Prevent metal fragments and pieces of wire from dropping inside the SafetyOne housing. Put a
cover on the SafetyOne during installation and wiring. Ingress of such fragments and chips may
cause fire hazard, damage or malfunction.
z
Install SafetyOne, so that there is adequate distance from the walls, heat generating bodies, and
peripherals, taking into consideration space requirements for maintenance and ventilation.
z
Install SafetyOne on 35mm DIN rails with BNL6 mounting clips (sold separately) on both sides of
SafetyOne.
z
Wire the connectors with conforming cables or ferrules.
z
Ground FE terminal to assure electromagnetic compatibility.
z
Use common 0V DC, if different power supplies are used for SafetyOne and other devices (ex.
safety light curtain.
z
Wire the inputs and outputs so that they are separated from power lines.
z
When overcurrent flows into output terminals, the protective function turns off the output. However,
when overcurrent status lasts long, internal protective elements will fuse. To protect the internal
elements, insert fuses of double the rated value to each terminal.
z
Use IEC60127 approved fuses on the power line of SafetyOne. (This is required for equipment
incorporating SafetyOne that is destined for Europe.)
z
When disposing of SafetyOne, handle it under the laws and regulations of the country in which it
is disposed.
