2. Before operating the unit
Precautions when installing the unit
12. Handling of a power cord
Never use electrical power cords bundled. When these are used bundled, they might
overheat causing a fire.
Do not convert, forcibly bend, twist or pull the power cord. Otherwise, a fire or an electrical
shock may result.
Do not place the power cord under a desk or a chair, or sand between objects to avoid it
from being damaged. Otherwise, a fire or an electrical shock may result.
Do not place the power cord close to a stove or other heat generating device. Sheath of the
cord may burn and result in a fire or an electrical shock.
If the power cord should be damaged (exposure of core wire or disconnection), immediately
turn the main unit off, pull out the power cord (plug) out of the power supply and ask your
dealer to replace the cord. Otherwise, a fire or an electrical shock may result.
Connect the power cord to an appropriate wall outlet.
13. Be sure to connect the ground wire.
・ When there is no ground terminal available, class D grounding work is necessary and
please consult your dealer or our nearest sales office.
・ Be sure to connect the ground wire to the wall outlet securely.
We recommend use of a ground type outlet
tap.
When there is no ground terminal.
In this case, class D grounding work is
necessary and please consult your dealer or
our nearest sales office.
When a bipolar type outlet tap is used
Insert the ground adaptor included as an
option, into a power plug confirming the
polarity of the outlet. Connect the grounding
wire (green) of the ground adaptor to the
ground terminal on the power supply
equipment.
Never connect the ground wire to anything other than the ground terminal such as gas pipe,
water pipe, or telephone line. Otherwise, an accident or a malfunction may result.
14. When you operate the unit for the first time
When you operate the unit for the first time at a higher temperature, the unit may generate
an odor. This is due to decomposed bonding material contained in heat-insulation material
and is not a malfunction of the unit. We recommend operating the unit at the highest
temperature once before starting its regular operation.
