Periodic Inspection
If the current stops flowing to either the GS1 or GS2 terminal while the safety function is
operating, the Inverter cuts off output. Accordingly, absence of defect in GS1 and GS2 wirings
must be inspected periodically. Be sure to conduct a periodic inspection once a year.
The wiring inspection method for GS1/GS2/EDM is shown below.
Precautions
 To make sure the safety function operates normally, evaluate the overall safety system against all
risk factors.
 The safety function does not mean the input is cut off or output is electrically insulated. Before
installation or maintenance work, turn off the Inverter input power supply.
 The wires used for the safety function must be 30 m or shorter.
 If common GS1 and GS2 are used for two or more Inverters, be sure to install a diode according
to "Note on Use of Multiple Inverters" on page 2-24. GS1 and GS2 may turn ON, thus causing the
Inverter to produce output even in the safety mode.
