B-iii
WARNING
DC power supply units must satisfy all of the conditions below so that the F3SN-B can comply with the applicable
standards IEC 61496-1, and UL 508.
•
The power supply voltage must be within specified ratings (24 VDC ± 10 %).
•
The power supply is connected only to the F3SN-B and to the devices related to the electro-sensitive protective
function of the F3SN-B, such as a safety controller and muting sensors, and it has enough rated current for all the
devices. The power supply must not be connected to other devices or machines.
•
The power supply uses double or reinforced insulation between the primary and secondary circuits
•
The power supply automatically resets overcurrent protection characteristics (voltage drop).
•
The power supply maintains an output holding time of at least 20 ms.
•
The power supply must have output characteristics of Class 2 Circuit of Limited Voltage-Current Circuit as defined in
UL508 (see “2-4-1 Remark”).
•
The power supply must conform to regulatory requirements and standards, regarding EMC and electrical equipment
safety, of the country where the F3SN-B is installed and where machinery will be operated. Example: The EMC
Directive (industrial environment) and the Low Voltage Directive in EU.
FG (frame ground terminal) must be connected to PE (protective earth) when using a commercially available switching
regulator.
A qualified person must confirm that installation, inspection and maintenance of the F3SN-B are implemented correctly as
determined by local regulations where the equipment is installed and used.
Do not disassemble, repair or modify the F3SN-B.
Do not use the F3SN-B in a reflective configuration, otherwise detection may fail. (Chapter 2-1)
