2. Safety Precautions on Wiring
WARNING
Mandatory
Connect the cables while the power
is off.
Otherwise, it may cause an electric
shock or failure.
Mandatory
When wiring the module, use crimp
contacts with sheath, or cover it
with tape.
Otherwise, exposed conductors may
cause an electric shock.
Mandatory
Install the terminal block cover
securely to the terminal block.
Exposed conducting parts may cause an
electric shock.
CAUTION
Mandatory
Connect an external power supply
that matches the rating.
Otherwise, it may cause an explosion or
fire.
Mandatory
Wiring work must be done by
qualified experts.
Wrong wiring may cause a fire, electric
shock, or failure.
Mandatory
Install a fuse that matches the
current capacity to the external
circuit for overload protection of the
relay output module.
Otherwise, a load short-circuit may
cause an accident or damage to the
machine.
Mandatory
When using the contact relay used
for relay output, check the contact
life.
If the contact life of the relay is expired,
an output error may occur due to a
defective contact, resulting in an
accident or damage to the machine.
Contact relays have a life due to wearing
of the contact. If the life is expired,
replace it with a new one.
Mandatory
Install the battery before use.
If the RAM is operated without any
battery, memory data or programs may
be lost, causing an accident or damage
to the machine due to malfunction.
Replace the battery according to the
battery replacement cycle guideline.

Unified Controller nv series TC-net I/O system 8ch-Pulse Input Module PI918 Functional Manual
v
Mandatory
Turn on the power in the following
order:
Turn on the power of the nv series, and
then turn on the I/O module supply
external power and external load power.
If this order is not followed, it may cause
an accident or damage to the machine
due to malfunction.
Mandatory
For system safety, turn off the load
power before the power of the nv
series.
If this order is not followed, it may cause
an accident or damage to the machine.
Share the external power supply for the
I/O module with the load power supply
whenever possible. If this is not
possible, construct the system so that
the external power supply and load
power supply are turned off
simultaneously.
Mandatory
Construct the emergency stop
circuit and interlock circuit outside
the nv series.
Otherwise, it may cause an injury
accident or damage to the machine if
failure or malfunction occurs in the nv
series.

6. Checking the Warning Label on the Main Body
Check that warning label is attached on the main body.
If the label is missing or hard to read due to stain, contact our service department.
[Warning symbols on the nv series main body]
This symbol is a warning symbol for dangerous parts. It is attached on plac
es
where there is a risk of an electric shock or a risk of damage to the main body
due to wrong wiring.
Note the following where this symbol is present.
●Touching the power input terminal of the power supply module while the power is on
causes an electric shock and is very dangerous.
Do not touch the power input terminal.
●For safety, turn off the power before wiring or performing maintenance and
inspection.
●Wire the power input terminal correctly, and avoid applying any voltage exceeding
the specified voltage range. It may cause failure or damage.
●Perform connector connection of the nV-Tool port after turning off the power of the
nV-Tool (such as the PC).
Turn on the power of the nV-Tool after connection.
Be careful not to short-circuit the connector pins with the connector cover.
[Warning stickers]
The warning sticker as shown in the
left figure is attached to the power
terminal of the nv series (except for
power supplies below 24V).
Remove the sticker from the mount,
and attach it on the main body of the
nv series, or on a location near the nv
series where it can be seen easily.
There are stickers in both Japanese
and English. Use the one that suits
your need.
When wiring, remove the sticker
mount.
If the sticker is damaged, contact
you
r distributor.

●Use of sample programs
•Use the sample programs described in the operation manual after performing an
operation check.
Make sure to perform an operation check before actual operation to avoid an accident
due to malfunction.
•Do not drop, bump, or apply strong shocks to the device or module.It may cause
failure.
●Battery replacement
•Battery replacement can be done while the unit is energized or not energized. When
replacing the battery while the unit is not energized, complete the replacement within
3 minutes. If the unit is left without a battery for a long time, the content of the RAM
memory may be lost.
•The Battery Normal LED (BAT) may illuminate during battery replacement. This is not
an error.
If the voltage decreases with the battery installed, the state will be detected normally
and the LED goes off.
•The battery voltage is not compatible with manganese batteries or alkaline batteries.
Do not mix them.
•Do not use a battery when 3 years or more have passed since the production date.
●Maintenance
•Place a module removed from the unit on a conductive mat or conductive bag (used for
a backup board) on a grounded table.
Otherwise, parts may be damaged due to static electricity.
•Before touching the device or module, touch a grounded metal to discharge the static
electricity of your body. Otherwise, it may cause malfunction or failure due to static
electricity.
