IMPORTANT
• The temperature specication 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 unit. When installing YFGW610 in a cabinet, note
that the temperature specication is not in respect to the ambient temperature of the cabi-
net. Provide cooling fans in the cabinet if needed.
• Avoid exposing YFGW610 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 akes, carbon particles, or any other type of dust that are conductive.
• Avoid existence of corrosive gases such as hydrogen sulde, sulfurous acid gas, chlorine,
and ammonia.
n YFGW610 Vibration Criteria
Ensure that if the frequency of vibration at the installation location is 58 Hz or less, the total
amplitude is maintained less than 0.15 mm. If the vibration frequency is greater than 58 Hz, nd
alocation that will meet the following condition:

n Radio Device Noise to YFGW610
The following shows general requirements when using a radio device such as transceivers; how-
ever, as a general rule, close the cabinet door when using a radio device:
• Transceivers that have 3 W of output power or less should be at least 1 m away. Transceiv-
ers that have 10 W of output power or less should be at least 2 m away.
• Radio devices that have 1 W of output power or less including cellular phones and cordless
phones should be at least 1 m away.
• The eld wireless device radio output is about 10 mW. There is no impact for YFGW610, but
keep to 1m than the same way as the 1 W output radio device.
