• When using any of the PS-A’s optional devices, be sure to check that device’s speci-
fications 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 Win-
dows
®
2000 or XP (classic) [Control panel]-[Power Options]- [Power Options Proper-
ties]-[Power Schemes]- [Turn off hard disks] selection to turn the hard disk off when the
unit is not being operated. A setting of 5 minutes is recommended.

Installations
1. Installation Requirements
• For easier maintenance, operation, and
improved ventilation, be sure to install the
PS-A at least 50mm [1.97 in.] away from
adjacent structures and other equipment.
• Be sure that the surrounding air tempera-
ture and the ambient humidity are within
their designated ranges. (Surrounding air
temperature: with HDD 5 to 50°C without
HDD 0 to 50°C, Ambient humidity: 10 to
90%RH, Wet bulb temperature: 29°C or
less, )
When installing the PS-A 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 PS-A to exceed its
standard operating temperature.
2. PS-A Installation
(1) Create a Panel Cut following the dimen-
sions in the table below.
(2) Confirm that the installation gasket is
attached to the PS-A unit and then place
the PS-A unit into the Panel from the front.
• It is strongly recommended that you
use the installation gasket, since it
absorbs vibration in addition to repel-
ling water.
For the procedure for replacing the
installation gasket, refer to “PS-3710A/
PS-3711A Series Hardware Manual”.
(3) Insert each fastener’s hook into the slot
and tighten it with a screwdriver. Insert
the installation fasteners securely into
the insertion slot recess. There are eight
insertion slots.

ply is completely turned OFF, via a
breaker, or similar unit.
• Supplying a power voltage other than
that specified can damage the PS-A
and the power supply.
• Since the PS3710A-T42-24V 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.
• When the FG terminal is connected, be
sure the wire is grounded. Not
grounding the PS-A 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 cord, use the fol-
lowing items when performing wiring.
(Items are made by Phoenix Contact.)
• Accompanying AC type power supply
plug is CA7-ACCNL-01 from Pro-face or
FKC2.5/3-STF-5.08 is manufactured by
Phoenix Contact.
• Accompanying DC type power supply
plug is CA7-DCCNL-01 from Pro-face or
GFKC2.5/3-STF-7.62 is manufactured by
Phoenix Contact.
Connecting the Power Cord
(1) Confirm that the power is not supplied to
the PS-A unit.
(2) Push the Opening button with 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 in place.
(4) After inserting all three pins, insert the
Power Plug into the Power Connector at
PS-A. Fix the plug with two (2) slot
screws.

1. 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 Plug.
• The PS-A 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 PS-A
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.
• Connect a surge absorber to handle power
surges.
• Be sure to ground the surge absorber
(E1) separately from the PS-A unit
(E2). Select a surge absorber that has
a maximum circuit voltage greater than
that of the peak voltage of the power
supply.
2. 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 applica-
ble standard.
• The SG (signal ground) and FG (frame
ground) terminals are connected internally
in the PS-A unit.
When connecting the SG line to another
device, be sure that the design of the sys-
tem/connection does not produce a short-
ing loop.
• The grounding wire should have a cross
sectional area greater than 2mm2. Create
the connection point as close to the PS-A
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.
3. Input/Output Signal Line Cautions
• All PS-A Input and Output signal lines
must be separated from all operating cir-
cuit (power) cables.
• If this is not possible, use a shielded cable
and ground the shield.

mended to attach a ferrite core to the
power cord.
Attaching the Power Switch cover
For the AC type to conform to ANSI/ISA
standards, the Power Switch cover needs to
be attached to the main unit.
To prevent the USB cable
from coming off
Attaching the USB Cable Clamp
(1) Place the PS-A unit face-down on a flat
surface as shown below. Your PS-A 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
second 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.
(2) As shown, insert the USB Cable Clamp’s
band through the Bridge. Pass the USB
cables through the Cable Clamp’s band
and securely tighten the clamp band
around the cables.
• 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 interfering 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.

• The PS-A unit’s rear face is not approved as an
enclosure. When building the PS-A unit into an
end-use product, be sure to use an enclosure that
satisfies standards as the end-use product’s overall
enclosure.
• The PS-A unit must be used indoors only.
• Install and operate the PS-A with its front panel
facing outwards.
• If the PS-A is mounted so as to cool itself naturally,
be sure to install it in a vertical panel. Also, it’s rec-
ommended that the PS-A should be mounted at
least 50mm [1.97in.] away from any other adjacent
structures or machine parts. The temperature must
be checked on the final product in which the PS-A
is installed.
• For use on a flat surface of a Type 4X (Indoor Use
Only) and/or Type 12 Enclosure.
• Type 4X (Indoor Use Only) and/or 12 Enclosure,
when the hatch for Front USB Port is secured with a
screw.
