2.4.2 Mounting YQ to NQ

(1) After confirming that there are no broken or bent YQ contact pins, fit the YQ in the NQ and fasten it using the
supplied YQGUIDE (for the fastening method, see the next step, (2)). If repeatedly inserting and removing,
be sure to inspect the YQ pins before fitting. If pins are bent, correct them using something thin and flat
such as the edge of a knife.
(2) Fasten YQ to the NQ on the target system using the supplied YQGUIDE. Fasten the screws equally in the
four corners using the supplied flat-blade screwdriver or a torque driver.
YQGUIDE is 0.054 Nm (MAX.). Too great tightening causes bad connections.
However, four screws for fitting to the NQ (M2 x 10 mm / 4 units) are included with the YQ.

2.4.3 Plugging 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 plug in.
- When plugging or unplugging, press on the NQ, YQ, and SA with a finger so that there is no force on the NQ.
- When plugging or unplugging, be careful of the direction of wiggling.
As a tool when unplugging, insert some kind of thin non-conductive material such as a wooden stick between the YQ
(SA) and EA and wiggle while slowly unplugging. Be careful since the connector will be damaged if this is done in
the wrong direction.
