Safety Instructions
Indicates a potentially hazardous situation
which if not avoided, may result in minor
injury or moderate injury.
Do not apply voltages exceeding 250V between a lead
wire and a metal fitting.
Pay attention to perform an insulation test because it could
damage the insulation of the lead wire and cause failure.
These instructions must be followed when using the
product in an interlocking circuit:
.Provide double interlocking through another system
such as mechanical protection.
.Check the product regularly to ensure proper operation.
Otherwise malfunction can cause an accident.
These instructions must be followed when performing
maintenance work:
.Turn off the power supply
.Stop the air supply, exhaust the residual pressure and verify
that the air is released before performing maintenance work.
Otherwise it can cause injury.
Perform a proper functional check after completing
maintenance work.
Stop operation when an abnormality is observed or the product is
not working properly.
Safety cannot be assured due to unexpected malfunctions.
NOTE
The direct-current power supply should be a UL authorized power
supply.
