Mounting method
Mounting pitch
Panel cutout dimensions: 92 0
＋0．8×45 0 ＋0．6mm
Panel thickness: 0.6 to 3.5mm（Degree of protection IP65)
3.6 to 10mm（Degree of protection IP20）
If the material of the panel is aluminum, it may
be deformed due to its weak strength. So, it is
recommended to use the thickness of
aluminum panel sheet with at least 1.5mm.
Mounting pitch（Refer to the Right figure）
Mounting method to panel
1Insert the main unit fitted with the waterproof packing into the hole, from the panel
front, and insert the attached bracket to the ditch on both sides of the main unit.
Press the bracket as shown by arrow ①until the main unit is stably stays and fix the
bracket. Do not remove it as the packing acts as stopper too. Refer to the side view
drawing of the bracket mounting shown below.
2To fix the main unit more firm, press the back part (center part) of the bracket
indicated by arrow ②by screwdriver, which enhances the stopper strength.
! Caution
 When the bracket is pressed by minus screwdriver, press it to the
direction as shown in arrow ②.
The pressing of other part may cause the damage of bracket.

Dismounting
1The lever lock of bracket can be released by extending the lever outward about 1 mm
by fingers as shown in figure below.
2Keep extending the lever outward, slide the bracket backward of the main unit and
remove it from the ditch.
! Caution
The extension of the lever or the stress to it by metallic piece like
screwdriver for a long time may damage the lever.

Wiring method
Remove the terminal base cover of the rear side terminal and conduct the wiring. Make sure
that the terminal base cover is attached after wiring. If both options of comparison output and
analog output are used, first complete the wiring of the comparison output and then start the
wiring of analog output.
Notes for wiring
! Warning
 To avoid an electrical shock, turn the power off when wiring.
 Do not conduct wiring at moistened place or by wetted hands. There may
be risk of electric shock.
 Do not touch the terminals when turning the power on. There may be risk
of electric shock.
! Caution
 Power supply and load should be within the suitable range as prescribed
in specification. Negligence may cause the damage of products.
 Power supply should reach the rated power within a second.
 After the power is OFF, pause more than 10 seconds before the power ON
again.
 Do not use the product with wrong wiring. It may be the cause of product
damage.
◆
Others caution during wiring
 Always use input line and power line independently. If input line and power line are wired in
parallel, it may cause an in stability of the display.
 When the auxiliary relay is operated by the relay output to run the electro- magnetic switch
or big size relay, take the noise preventive measures.
In case that the noise is frequently occurred, it will be effective to store the product in the
shielded housing or to insert the power source line filter or insulated transformer.

About the crimp terminal
Direction of crimp terminal
Recommended crimp terminal：V1.25-FS3
（Made of Fuji Terminal Industry Co., Ltd）
Ext. diameter of covered cable：Max.φ3.3
Terminal screw：M3
Crimp terminal: Refer figure at the right
! Caution
 For the column B (RS-232C and RS-485), column C and D terminal blocks,
apply just one crimp terminal per terminal location.
 Do not wire the parallel connection, using two crimp terminals
(overlaying) at the same terminal location. It stresses the internal PCB
and may cause the failure or trouble. As for the A column and E column
terminal blocks, up to two crimp terminals per terminal location are
acceptable.

Power supply connection
Connect the power supply at terminal No. E1-E3.
Power supply voltage is mentioned on the
terminal nameplate at the time of shipment.
○AC power supply
AC100 to 240V 50/60Hz
Permissible range AC 90 to 250V
○DC power supply
DC 24V
Permissible range DC24V±10%
! Caution
 Do not use the voltage out of permissible range. It may be the cause of
equipment damage.
 Power on / off, power supply should reach up to rated voltage or shut
down within 1 second.
 After the power is OFF, pause more than 10 seconds before the power ON
again.
 GND (ground) terminal
In case of frequent noise generation on the power source line, it is
effective to earth the ground terminal directly to the ground. If the
instrument is not affected by environmental noise, the grounding can be
omitted. In this case, take care for the ground terminal not to touch
other input terminals, as it is charged with neutral electric potential of
power source voltage.
