QB-V850ESFJ3 Preliminary User’s Manual ZUD-CD-05-0149 29/57
2.6.3 Inserting EA into YQ
Match the pin 1 position of the YQ or SA (corner cuts match in both) to the pin 1 position of the EA and insert it.
•
When inserting or removing, press on the TC, YQ, and SA with a finger so that there is no force on the TC.
•
When inserting or removing, be careful of the direction of wiggling.
As a tool when removing, insert some kind of thin non-conductive material such as a wooden stick between the
YQ (SA) and EA and wiggle it while slowly removing. Be careful since the connector will be damaged if this is done
in the wrong direction.
2.6.4 Precautions for handling TC, YQ, SA, and CA
(1) When taking the TC from the box, press down on the body and take out the sponge first.
(2) Since the pins of the YQ are thin and easily bent, be careful. When inserting it in the TC, confirm that there
are no bent pins.
(3) When screwing a YQ soldered to a board to the TC, fasten the screws in four places in turn using a #0 or #1
Phillips precision screwdriver or torque driver after tentatively tightening them. Fix the torque at 0.054 Nm
(MAX.). If just one place is overtightened, it may cause poor contact. Moreover, a board being connected to
the YQ must have accessory holes in prescribed positions (4 places:
φ
2.3 mm or
φ
3.3 mm). The
φ
3.8 mm or
φ
4.3 mm that is the screw head size is an area where wiring is prohibited.
(4) In YQ and SA removal, since there is a danger of YQ pins being bent or broken when prying and wiggling,
remove them gradually using a flatbladed screwdriver from four directions. Moreover, to connect and use
the YQ and SA, screw the YQ to the TC according to the YQGUIDE (sold separately) using a 2.3 mm
flatbladed screwdriver and then connect it to the SA. Fix the torque at 0.054 Nm (MAX.). If even one place
is overtightened, it may cause poor contact.
(5) For the TC, YQ, and SA, since there is a danger that cleaning fluid on the structure will remain in the
connector, do not perform cleaning.
(6) TC, IC, and YQ cannot be used in combination.
(7) An TC/YQ system cannot be used in an environment of vibrations or shocks.
(8) It is assumed that this product will be used in system development and evaluation. Moreover, when used in
Japan, Electrical Appliance and Material Control Law and electromagnetic disturbance countermeasures
have not been applied.
(9) Since there are rare cases of shape change if the box is left for a long time in a place where it is 50
°
C or
higher, for safekeeping, store it in a place where it is no higher than 40
°
C and direct sunlight does not hit it.
(10) For details about handling the TC, YQ, and SA, see the NQPACK series technical materials at the website of
Tokyo Eletech Corporation.

(11) Check pin adapter QB-144-CA-01
The check pin adapter QB-144-CA-01 is an optional product for IECUBE, and can be used to measure the
waveform between IECUBE and the target system.
Since the pins on the QB-144-CA-01 do not correspond to the pin layout in each device, the pin header
cover must be mounted according to the device to be used.
For mounting methods of the pin header cover, refer to
