1
External
power sup-
ply
Is the power supply voltage mea-
sured at the terminal block within
standards?
Within the power supply
voltage range
Use a voltage tester to check the power
supply at the terminals. Take necessary
steps to bring the power supply within the
power supply voltage range.
2
I/O power
supply
Is the power supply voltage mea-
sured at the I/O terminal block
within standards?
Voltages must be within
I/O specifications of each
NX Unit.
Use a voltage tester to check the power
voltage at the terminals. Take necessary
steps to bring the I/O power supply within
NX Unit standards.
3
Ambient
environ-
ment
Is the ambient operating tem-
perature within standards?
0 to 55
°
C
Use a thermometer to check the tem-
perature and ensure that the ambient
operating temperature remains within the
allowed range of 0 to 55
°
C.
Is the ambient operating humid-
ity within standards?
Relative humidity must be
10% to 95% with no con-
densation.
Use a hygrometer to check the humidity
and ensure that the ambient operating
humidity remains between 10% and
95%.
Make sure that condensation does not
occur due to rapid changes in tempera-
ture.
Is it subject to direct sunlight?
Not in direct sunlight
Protect the Controller if necessary.
Is there an accumulation of dirt,
dust, salt, metal powder, etc.?
No accumulation
Clean and protect the Controller if neces-
sary.
Is there water, oil, or chemical
sprays hitting the Controller?
No spray
Clean and protect the Controller if neces-
sary.
Are there corrosive or flammable
gases in the area of the Control-
ler?
No spray
Check by smell or use a sensor.
Is the Unit subject to shock or
vibration?
Vibration resistance and
shock resistance must be
within specifications.
Install cushioning or other vibration and
shock absorbing equipment if necessary.
Are there noise sources near the
Controller?
No significant noise
sources
Either separate the Controller and noise
source, or protect the Controller.

Installation
and wiring
Are the DIN track mounting
hooks for each NX Unit securely
locked?
No looseness
Securely lock the DIN track mounting
hooks.
Are the cable connectors fully
inserted and locked?
No looseness
Correct any improperly installed connec-
tors.
Are there any loose screws on
the track End Plates (PFP-M)?
No looseness
Tighten loose screws with a Phillips-head
screwdriver.
Are the NX Units connected to
each other along the hookup
guides and until they touch the
DIN track?
You must connect and fix
the NX Units to the DIN
track.
Connect the NX Units to each other
along the hookup guides and until they
touch the DIN track.
Are there any damaged external
wiring cables?
No visible damage
Check visually and replace cables if nec-
essary.
