6.3.1 How to draw sub unit out
(1) Removing the cover
(2) Drawing the sub unit
Hold the lock levers, which are located at both
sides of the cover, on their front sections. Take off
the cover straight toward you while pushing the
levers inwards.
Grip the draw-out handles (located at both sides of
the front of the sub unit). Press the locking pieces
installed in the upper portion of the draw-out
handles with your thumbs to pull the sub unit
towards you.
Note) The sub unit is so designed that it can not be
removed unless it is pulled out with a
relatively strong force, in consideration of
quake-proof measures. When the relay unit
is to be removed independently, it is
recommended to draw it out with the case
held by other operator.
When about a half portion of the sub unit is pulled
out of the case, just stop the drawing motion. Then,
hold the top and bottom of the sub unit to pull it
out completely, in order to prevent the unit from
falling.
Note) Be careful not to touch the printed circuit
board and parts inside the sub unit.
