Environmental Specifications
• When using any of the PL’s optional devices, be sure to check that device’s specifica-
tions for any special conditions or cautions that may apply to its use.
• Be aware that not only does the Hard Disk have a fixed lifetime, but that accidents
can always occur. Therefore, be sure to back up your Hard Disk’s data regularly, or
prepare another Hard Disk unit that can be used for backup.
• The Hard Disk lifetime given here may be reduced due to unforeseen environmental
factors, however, generally speaking, the disk should last for 20,000 hours (of opera-
tion) or approximately 5 years, whichever comes first at an operating temperature of
20°C and 333 hours of operation per month. (HDD access frequency of 20% or less)
• Using the Hard Disk in an environment that is excessively hot and/or humid will
shorten the disk’s usage lifetime. A wet bulb temperature of 29°C or less is recom-
mended. This is equivalent to the following data.
• In order to extend the lifetime of the hard disk, Pro-face recommends you set the
Windows®2000’s [Control panel]-[Power Management option]-[Turn off hard disks]
selection or the Windows®XP’s [Control panel]-[Performance and Maintenance]-
*1 When the total of the expansion slot power and theexternal load power exceeds 15W, the length of
the allowable voltage drop will be 20ms or less. For details, refer to the chart below.

• Be sure to use only the rated voltage
level when using pin #1 (+12V) for
external power output. Failure to do so
can lead to a unit malfunction or acci-
dent.
• For the circuit diagram, refer to “PL3000
Series Reference Manual”.
Installations
• Before installing the PL unit on the
panel, detach the control box from the
front module to configure the settings
of the internal switches.
1. Installation Requirements
• For easier maintenance, operation, and
improved ventilation, be sure to install the
PL at least 50mm [1.97 in.] away from
adjacent structures and other equipment.
For the face to which the cable is con-
nected, however, a space of 120 mm [4.72
in.] or more is necessary for cable curve.
• Be sure that the surrounding air temperature
and the ambient humidity are within their
specified ranges.
When installing the PL on the panel of a
cabinet or enclosure, “Surrounding air tem-
perature” indicates both the panel face and
cabinet or enclosure’s internal temperature.
• Be sure that heat from surrounding equip-
ment does not cause the PL to exceed its
standard operating temperature.
2. PL Installation
(1) Create a Panel Cut following the dimen-
sions in the following table. Also, deter-
mine the panel thickness according to the
panel thickness range with due consider-
ation of panel strength.

Wiring
• To avoid an electric shock, prior to con-
necting the PL unit’s power cord terminals
to the power terminal block, confirm that
the PL unit’s power supply is completely
turned OFF, via a breaker, or similar unit.
• Any other power level can damage
both the PL and the power supply.
• Since DC type has no power ON/OFF
switch, be sure to attach a breaker-
type switch to its power cord.
• When the FG terminal is connected, be
sure the wire is grounded.
1. Wiring the AC type power supply cable
• When the FG terminal is connected, be
sure the wire is grounded. Not
grounding the PL unit will result in
excessive noise. Use your country’s
applicable standard for grounding.
Power Cord Specifications
Use copper conductors only.
Wiring
When connecting the power code, use the
following items when performing wiring.
(Items are made by Phoenix Contact.)
• Accompanying power supply connector is
a CA7-ACCNL-01 of Pro-face or FKC2,5/
3-STF-5,08 of Phoenix Contact.
Connecting the Power Cord
(1) Confirm that the power is not supplied to
the PL unit.
(2) Push the Opening button by a small and flat
screw driver to open the desired pin hole.
(3) Insert each pin terminal into its each
hole. Release the Opening button to
clamp the pin place.
(4) After inserting all three pins, insert the
Power Plug into the Power Connector at
PL. Fix the plug with two minus screws.
• Confirm that all wires are connected
correctly.
• The torque required to tighten these
screws is 0.5 to 0.6 N•m [5-7Lb•In].
• To prevent the possibility of a terminal
short, use a pin terminal that has an
insulating sleeve.
2. Wiring the DC type power supply cable
• When the FG terminal is connected, be
sure the wire is grounded. Not ground-
ing the PL unit will result in excessive
noise. Use your country’s applicable
standard for grounding.

Contact.
When connecting the power code, use the
following items when performing wiring.
(Items are made by Phoenix Contact.)
Connecting the PL Power Cord
(1) Confirm that the power is not supplied to
the PL unit.
(2) Loosen three screws in the center of the
Power Connector (plug).
(3) Strip the power cord, twist the conductor’s
wire ends, insert them into the pin terminal
and crimp the terminal. Attach the terminal
to the Power Connector.
• Use a flat-blade screwdriver (Size 0.6 x
3.5) to tighten the terminal screws.
The torque required to tighten these
screws is 0.5 to 0.6 N•m [5-7Lb•In.].
• Do not solder the cable connection.
(4) Attach the Power Connector (plug) to the
PL and fix it to the PL main unit with
right/left tightening screws.
3. Power Supply Cautions
• Input and Output signal lines must be sepa-
rated from the power control cables for
operational circuits.
• To improve the noise resistance, be sure to
twist the ends of the power cord wires
before connecting them to the Power con-
nector (Plug).
• The PL unit’s power supply cord should
not be bundled with or kept close to main
circuit lines (high voltage, high current), or
input/output signal lines.
• To reduce noise, make the power cord as
short as possible.
• If the supplied voltage exceeds the PL
unit’s range, connect a voltage transformer.
• Between the line and the ground, be sure to
use a low noise power supply. If there is an
excess amount of noise, connect a noise
reducing transformer.

• The temperature rating of field installed
conductors: 75°C only.
• Use voltage and noise reducing trans-
formers with capacities exceeding
Power Consumption value.
• Branch Circuit Protective device shall be
use for rating 20A for DC24V input device.
• Connect a surge absorber to handle
power surges.
• Be sure to ground the surge absorber
(E1) separately from the PL unit (E2).
Select a surge absorber that has a maxi-
mum circuit voltage greater than that of
the peak voltage of the power supply.
4. Grounding Cautions
• Be sure to create an exclusive ground for the
Power Cord’s FG terminal. Use a grounding
resistance of 100Ω, a wire of 2mm2or thicker,
or your country’s applicable standard.
• The SG (signal ground) and FG (frame
ground) terminals are connected internally
in the PL unit.
When connecting the SG line to another
device, be sure that the design of the system/
connection does not produce a shorting loop.
• The grounding wire should have a cross
sectional area greater than 2mm2. Create
the connection point as close to the PL unit
as possible, and make the wire as short as
possible. When using a long grounding
wire, replace the thin wire with a thicker
wire, and place it in a duct.
5. Input/Output Signal Line Cautions
• All PL Input and Output signal lines must
be separated from all operating circuit
(power) cables.
• If this is not possible, use a shielded cable
and ground the shield.

To prevent the USB cable
from coming off
Attaching the USB Cable Clamp
(1) Place the PL unit face-down on a flat sur-
face as shown below. Your PL unit has
four USB connectors.
• When using two or more USB ports, be sure
to first connect one USB cable to the lower
USB connector, and then connect the sec-
ond USB cable to the upper USB connector.
• When using only one of the USB ports, be
sure to use the lower USB connector. This
allows you to securely clamp the USB
cable in the cable clamp.
• The USB cable clamp is not compatible
with the USB connector on the front face.
(2) Fix the USB holder with two screws.
The torque required to tighten these
screws is 0.5 to 0.6 N•m.
(3) As the figure shows, pass the USB Cable
Clamp’s band around the depressed sur-
face of the holder, twist the USB Cable
Clamp’s band around the USB cable, pull
the band in the direction of the arrow,and
then fasten the band using the clamp.
• Be sure the clamp is securely holding the
USB cable’s plug and collar.
• Be sure the clamp is positioned as shown
below, with the clamp pointing upwards - not to
the side. This is to keep the clamp from interfer-
ing with nearby connectors and their cables.
Removing the USB Cable Clamp
(1) To remove the clamp from the USB cables,
push down on the clamp strap’s clip to
release it while pulling up on the clamp.
