6. Wiring
● Earth the machine or the support where the device is mounted on to frame ground (F.G.).
Failure to do so could cause the malfunction of the product by noise, resulting in death
or serious injury. 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 invalid for the system stop, resulting in death or serious injury.
● In order that the output is not turned ON due to earth fault of the control output (OSSD 1
/ 2) wires, be sure to ground to 0V side (PNP output type) / +V side (NPN output type).
● When the synchronization cable is extended with a cable other than exclusive cable,
2
use a 0.2mm or more shielded twisted pare cable.
Make sure to insulate the ends of the unused lead wires.
<Reference>
Use a safety relay unit or an equivalent control circuit in safety for FSD.
● Power supply unit
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 not match or the wiring is improper, it may cause damage or
malfunction of this device.
<Reference>
A specialist who has the required electrical knowledge should perform the wiring.
The 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 SELV (safety extra low voltage) / PELV (protected extra low voltage) 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 the ground when using a commercially avail-
able 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 ori-
gin of the surge.
7) Power supply unit corresponding to CLASS 2 (only for requiring
