Requirements for Installation
Be sure to fulll the following requirements for safety purposes.
•
Overvoltage Category : Category
III
•
Pollution Degree : 3
•
Altitude : 1,000 m or less above the sea level
Overvoltage Categories refer to the level of Impulse Withstand Voltage protection
provided at the specied Pollution Degree.
Category III : Primary circuits of a device to which power is directly supplied from the
power distribution panel, and circuits from the distribution panel to outlets.
Note
The term was changed from "Installation Category" to "Overvoltage Category".
"Pollution Degree" is a degree of pollution severity.
Pollution Degree 3 : Conductive pollution or dry nonconductive pollution that becomes conduc-
tive due to condensation occurs. To be found in industrial environment or
construction sites (harsh environments).
Altitude means the height above sea level of the place where the machine is to be used.
Note
When the machine is used in a place that has an altitude of 1,000 meters or more,
consult with the Marketing Dept of Yamaha Motor Co., Ltd. or a sales agent.

Precautionary Measures before Installation
If the machine is installed in unsatisfactory environmental conditions, it may malfunction
due to damage or breakdown.
To avoid this, make preparations to install the machine as follows.
When the machine is scheduled to be transferred to another place, please contact the
marketing department or sales agency of Yamaha Motor Co., Ltd. beforehand.
Select a place solid enough to support the mass of the machine.
Note
It is recommended that the machine should be installed on the rst oor.
When the machine has to be installed on a oor other than the rst one, please contact
the marketing department or sales agency of Yamaha Motor Co., Ltd. for details.
Avoid any place that vibrates severely.
The ambient temperatures must be 20 ± 10°C and humidity 30 to 80%. Any dew
condensation must be avoided.
When the machine is transferred to another place and the ambient temperature rises more
than the surface of the machine, dew may condense under the condition described below.
Note that dew condensation may cause the machine to break down.
Condition of Dew Condensation
Dew may condense when the dierence (based on "Humidity (%)") between the ambient
temperature of the destination (the place where the machine was transferred) and the surface
temperature of the machine reaches the values or more in the table below.
Humidity (%) of Destination
Dierences between Ambient Temperature of
Destination and Surface Temperature of
Machine
80 3 °C or more
70 6 °C or more
60 8 °C or more
50 10 °C or more
40 14 °C or more
30 18 °C or more
Ensure that the selected place is free of electric noise, etc.
Precautionary measures (prevention of noise generation, etc.,) must be taken for other
equipment to prevent the machine from malfunctioning.
Do not expose the machine to combustible or corrosive gas.
