Warning
Calculate respective safety distances, taking into consideration the response time of the
SG-ONE, safety devices to be connected to the SG-ONE, and each other device that forms a
part of the system configuration.
Applicable safety performance is dependent on each system configuration.
Use a power supply that meets following required specifications:
-Conforms to the power supply rating of SG-ONE
-Has the functionality or the functional equivalent of the control voltage and current of class 2
circuit, as defined in UL508 or UL1310.
-Is in compliance with safety laws and regulations relating to electrical safety, EMC, and like under
the laws and regulations of the country in which it is being used.
Ground the V- line (0V DC) for ground diagnosis.
In the case of a new configuration or modified installation, be sure to perform a check for each
input and output function.
Implement protective measures that personal, other than safety responsible persons operating
the SG-ONE, are unable to modify the configuration.
Separate SG-ONE from devices and wires which are not according to class 2 circuit
requirements.
The following sentence is added in power supply requirments instead of a insulation condition.
- Complies with the SELV/ PELV circuit specified by EN 50178 or EN60950.
The following new sentence is added in the above "SAFETY PRECAUTIONS".
- The start switch has to be placed outside the danger zone and in a safe position from which there
is good visibility for checking that no person is within the danger zone.
