Wiring
<Reference>
Use a safety relay unit or an equivalent control circuit in safety for FSD.
2-5-1 Power Supply Unit
<Reference>
A specialist who has the required electrical knowledge should perform the wiring.
The DC power supply unit must satisfy the conditions given below.
1) Power supply unit authorized in the region where this device is to be used.
2) Power supply unit conforming to EMC Directive and Low-voltage Directive (only for requiring CE marking
conformation).
3) Power supply unit conforming to the Low-voltage directive and with an output of 100VA or less.
4) The frame ground (F.G.) terminal must be connected to ground when using a commercially available
switching regulator.
5) Power supply unit with an output holding time of 20ms or more.
6) In case a surge is generated, take countermeasures such as connecting a surge absorber to the origin of
the surge.
7) Power supply unit corresponding to CLASS 2 (only for requiring UL / cUL conformation)
«Additional information» As provided in IEC 60536 (CLASS: Protection against Electric Shock), this
power supply should require no ground earth and satisfy the insulation dis-
tance called double insulation or reinforced insulation.
In case the power supply conforms to Low-voltage directive and has an output
of 100VA or less, it can be used as a suitable product.
Earth the machine or the support where the sensor is mounted on to frame ground (F.G.).
Failure to do so could cause the malfunction of the product by noise, resulting in serious
injury or death.
Furthermore, the wiring should be done in a metal box connected to the frame ground (F.G.).
Take countermeasure against the system to be applied for this device so as not to carry out
the dangerous performance caused by the earth failure. Failure to do so could cause inva-
lid for the system stop, resulting in serious body injury or death.
Make sure to insulate the ends of the unused lead wires.
Wire correctly using a power supply unit which conforms to the laws and standards of the
region where this device is to be used. If the power supply unit is non-conforming or the wiring
is improper, it can cause damage or malfunction of this device.
