Wiring
Section 3-2
IMPORTANT
• Properly apply the specified voltage to the NE1A-series Controllerís
inputs. Applying an inappropriate DC voltage or any AC voltage may
cause reduced safety functions, damage to the NE1A-series Controller, or
a fire.
• Be sure to separate I/O cables from high-voltage/current lines.
• Use I/O cables of 30 m or less.
• Do not apply the power supply to the test output terminals. Doing so may
result in product damage or burning.
Wiring Output Devices
Refer to the following diagram for selection and wiring of output devices.
Relay with forcibly guided contacts
Use approved devices with forcibly guided contacts compliant with EN 50205.
For feedback, use devices with contacts capable of switching
micro-loads of 4 mA at 24 VDC.
Contactor
Use contactors with a forcibly guided mechanism and monitor the auxiliary NC
contact to detect contactor failures.
For feedback, use devices with contacts capable of switching micro-loads of 4
mA at 24 VDC.
Other devices
Evaluate whether devices used are appropriate to satisfy the requirements of
the safety category level.

WARNING
Serious injury may possibly occur due to breakdown of outputs. Do not connect loads
beyond the rated value to the safety outputs and the test outputs.
Serious injury may possibly occur due to loss of required safety functions. Wire the
NE1A-series Controller properly so that 24-VDC lines do NOT touch the safety outputs
and the test outputs accidentally or unintentionally.
Serious injury may possibly occur due to loss of required safety functions. Ground the 0-
V line of the power supply for external output devices so that the devices do NOT turn
ON when the safety output line or the test output line is grounded.
Serious injury may possibly occur due to loss of required safety functions. Use appropri-
ate components or devices according to the requirements given in the following table.
