3 Safety Precautions
Read these safety precautions carefully and make sure you understand them
before using the Programmable Terminal so that you can use it safely and cor-
rectly.
WARNING
SNever attempt repairs, modification or disassembly. You could sustain an elec-
tric shock.
SSwitch OFF the PT power before changing the backlight. You could sustain an
electric shock if you attempt to change the backlight while power is being sup-
plied.
Caution
SWhen disposing of a used backlight, comply with all local restrictions that apply
to its disposal.
SWhen replacing the battery, do not allow the battery terminals to touch the
board in the PT.
SIf not backed up by the built-in battery, the memory switch settings will be initial-
ized to the values set with the NT-series Support Tool when the power is turned
OFF. If a message indicating that the battery is low is displayed while the PT is
being used, replace the built-in battery immediately. For details on how to re-
place the battery, refer to Replacing the Battery (page 253).
SSwitch OFF the power supply to both the PT and the B7A Interface Unit before
installing the B7A Interface Unit, otherwise the PT or the B7A Interface Unit
may be damaged.
SSwitch OFF the power supply to both the PT and the B7A Interface Unit before
changing DIP switch settings.
SDo not use input functions, such as PT touch switches, for applications where
danger to human life or serious property damage is possible or for emergency
switch applications.
SDo not use the expanded I/O functions of the B7A Unit for applications where
danger to human life or serious property damage is possible or for emergency
switch applications.
SOn unpacking the PT, check its external appearance and confirm that there is
no damage. Also confirm that there is no abnormal noise on shaking the PT
lightly. The PT may malfunction if it is damaged.
SDuring work at the panel, be sure that no metal scraps enter the PT. Otherwise,
the PT may malfunction.
SThe thickness of applicable operation panel is 1.6 mm to 4.8 mm. All fittings
must be tightened uniformly to a torque of 0.5 to 0.6 N⋅m in order to ensure
water- and dust- resistance. The panel must not be soiled or warped, and must
be able to support an installation that will remain secure and strong.
SCarefully check wiring before switching ON the power.

3Safety Precautions
xiv
SDo not apply an AC power supply across the power supply terminals.
SUse a DC power supply with a low voltage fluctuation.
SWhen complying with EC low voltage directives use a power supply with rein-
forced insulation.
SFor the connection to the power supply terminal block, twisted-pair wires with a
2mm
2or greater cross sectional area and M 3.5 size crimp terminals must be
used. Tighten the screws on the terminal block to a torque of 0.8 N⋅cm. Other-
wise fire may occur.
SIf the DIP switch settings have been changed while power was supplied to the
PT, reset the power to the PT. The changes with the DIP switch become effec-
tive only after the power supply is reset.
SBefore switching ON the power for the first time, set pin 6 of DIP switch SW2 on
the PT to ON (it is set to OFF on shipping). If it is left OFF, messages will not be
displayed normally.
SPress the Abort touch switch on the PT when screen data transmission has
been completed. Unless this touch switch is pressed, the screen data will not
be correctly registered. If the Abort touch switch is pressed during transmis-
sion, the screen data will not be correctly registered.
SCheck the operation of screen data and ladder program thoroughly before ac-
tually using them.
SPress touch switches with a force of no greater than 30 N. Applying higher force
may cause glass to break, resulting in injuries or preventing operation.
SDo not press touch switches carelessly while the backlight is OFF or while
nothing is displayed on the screen. The system may operate unpredictably.
Press touch switches only after confirming system safety.
SAs far as possible, disconnect all devices connected to the output terminals be-
fore executing the output check. Otherwise, each time an output terminal
comes ON during the check operation, the outputs to the devices may be acti-
vated.
