Configuration of the control panel
Warning
Be careful when the control panel is powered on because a high
voltage is running through the parts inside the control panel and it is
very dangerous.
Do not allow any persons other than qualified personnel to open the
cover of the control panel. Otherwise, it may lead to an electric shock.
Caution
Be sure to open or close the cover with both hands to apply roughly the
same amount of force to the right and left sides.
For example, when the cover is opened or closed by using only the
handle on one side, uneven force applied to the right and left sides of
the cover may twist and distort the cover, resulting in disconnection or
damage of the cover.
Caution
When opening the cover, do not let go of the cover until it reaches the
stop position. Otherwise, a resulting impact may damage the cover
and/or other parts.
(1) Opening/closing the cover (for models with a
motor output of up to 3.7 kW)
c
Open the cover.
Put your hands on the handles on the right
and left sides of the cover, and pull the
cover toward you with both hands. At that
time, ensure that roughly the same amount
of force is applied to the right and left sides.
Do not let go of the cover until it reaches
the stop position
d
Close the cover.
Put your hands on the areas around the
right and left handles of the cover, and lift
the cover with both hands to close it.
Firmly press the cover until the latch is
securely locked in place.
