IMPORTANT
• The temperature specification during operation indicates the criterion of the temperature
at the air intake of the bottom portion of modules. Do not block ventilation holes, as it may
hinder the air-cooling capabilities of the body. When installing YFGW410 in a cabinet, note
that the temperature specification is not in respect to the ambient temperature of the cabi-
net. Provide cooling fans in the cabinet if needed.
• Avoid exposing YFGW410 to direct sunlight.
• Prevent condensation under any circumstance.
• The dust level of the room should not exceed 0.3 mg/m
3 . Under any circumstance, avoid
iron flakes, carbon particles, or any other type of dust that are conductive.
• Avoid existence of corrosive gases such as hydrogen sulfide, sulfurous acid gas, chlorine,
and ammonia.
• YFGW410 should not share a ground wire with other devices.
n YFGW410 Vibration Criteria
Ensure that if the frequency of vibration at the installation location is 58 Hz or less, the total am-
plitude is maintained less than 0.15 mm. If the vibration frequency is greater than 58 Hz, find a
location that will meet the following condition:
Acceleration (m/s 2 ) = 2π 2 x A x F 2 x 10 -3 < 9.8 (=1 G)
A: Total amplitude (mm)
F: Frequency (Hz)
The range of allowable total amplitudes is shown below.
