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

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

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.
