Yaskawa A1000 6-Phase/12-Pulse Input - Manual (Page 13)

2 Mechanical Installation
This section outlines specifications, procedures, and the environment for proper mechanical installation of the drive.
u Installation Environment
Install the drive in an environment matching the specifications in Table 2 to help prolong the optimum performance life of
the drive.
Table 2 Installation Environment
Environment Conditions
Installation Area Indoors
Ambient Temperature
Flange Type Enclosure: -10 °C to +40 °C (14 °F to 104 °F)
Non-Flange Type Enclosure: -10 °C to +50 °C (14 °F to 122 °F)
Drive reliability improves in environments without wide temperature fluctuations.
When using the drive in an enclosure panel, install a cooling fan or air conditioner in the area to ensure that the air
temperature inside the enclosure does not exceed the specified levels.
Do not allow ice to develop on the drive.
Humidity 95% RH or less and free of condensation
Storage Temperature -20 °C to +60 °C
Surrounding Area
Install the drive in an area free from:
• oil mist and dust
• metal shavings, oil, water, or other foreign materials
• radioactive materials
• combustible materials (e.g., wood)
• harmful gases and liquids
• excessive vibration
• chlorides
• direct sunlight.
Altitude Up to 1000 m without derating, up to 3000 m with output current and voltage derating.
Vibration
10 Hz to 20 Hz at 9.8 m/s 2
20 Hz to 55 Hz at 5.9 m/s 2 (Models 4T0058o to 4T0165o) or 2.0 m/s 2 (Models 4T0208o to 4T0675o)
Orientation Install the drive vertically to maintain maximum cooling effects.
NOTICE: Avoid placing drive peripheral devices, transformers, or other electronics near the drive as the noise created can lead to erroneous
operation. If such devices must be used in close proximity to the drive, take proper steps to shield the drive from noise.
NOTICE: Damage to Equipment. Drive heatsink air outlet temperature may be over 80 °C. Do not install components above the air outlet
that may be damaged by 80 °C air temperature.
NOTICE: Damage to Equipment. Prevent foreign matter such as metal shavings and wire clippings from falling into the drive during
installation. Failure to comply could result in damage to the drive. Place a temporary cover over the top of the drive during installation.
Remove the temporary cover before drive start-up, as the cover will reduce ventilation and cause the drive to overheat.
