Chapter3 INSTALLATION AND WIRING
This chapter describes methods and precautions for installing and wiring the
SafetyOne. Before starting installation and wiring, be sure to read “SAFETY
PRECAUTIONS” in the beginning of this manual and understand the
precautions described under WARNING and CAUTION.
Warning
● Turn off power to SafetyOne before starting installation, removing, wiring, maintenance, or
inspection of SafetyOne. Failure to turn power off may cause electrical shocks or fire hazard.
● Before operating SafetyOne, carefully read the instruction sheet and this manual, and ensure
that the environment conforms to the requirements of SafetyOne specifications. If SafetyOne is
operated in an environment that exceeds the specifications of SafetyOne, it causes impairment
of the safe operation of SafetyOne.
●. The installation, wiring, configuration, and operation of SafetyOne must be performed only by
“Safety responsible personnel”. Safety responsible personnel are personnel who have requisite
qualifications as being capable of safely carrying out each step, including designing, installation,
operation, maintenance, and disposal of SafetyOne. Personnel without the technical expertise
of the safety responsible personnel must not use SafetyOne.
● Installation of SafetyOne must be performed according to the instructions found in the instruction
sheet and this manual. Improper installation may cause the SafetyOne to fail.
● Use a power supply that meets following required specifications:
-Conforms to the power supply rating of SafetyOne
-The primary and secondary circuits are separated by double insulation or reinforced insulation.
-Has the functionality or the functional equivalent of the control voltage and current of a class 2
circuit, as defined in UL 508 or UL 1310.
-Is in compliance with safety laws and regulations relating to electrical safety, and EMC, under
the laws and regulations of the country in which it is being used.
● Ground the V-line (0V DC) for ground fault diagnosis.
● In the case of a new configuration or modified installation, be sure to perform a check for each
input and output function.
● Separate SafetyOne from devices and wires which are not according to class 2 circuit
requirements.
Caution
● SafetyOne is designed for installation in an enclosure. Do not install SafetyOne outside an
enclosure. Install SafetyOne in enclosure with a rating of IP54 or higher.
● Install SafetyOne in environments described in the catalog, instruction sheet, and user’s manual.
If SafetyOne is used in places where the SafetyOne is subjected to high temperature, high
humidity, condensation, corrosive gases, excessive vibrations, and excessive shocks, then
electrical shocks, fire hazard, or malfunction may result.
● Environment for using the SafetyOne is “Pollution degree 2”. Use SafetyOne in environments of
pollution degree 2 (according to IEC/EN 60664-1).
