Vibration Criteria of DTSXL System
Ensure that if the frequency of vibration at the installation location is 58 Hz or less, the
total amplitude is kept below 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
) = 2 π
2
x A x F
2
x 10
-3
< 9.8 (=1G)
where
A: Total amplitude (mm)
F: Frequency (Hz)
The allowable range for total amplitude is shown below.


Radio Device Interference to DTSXL System
The following shows general requirements when using radio devices such as
transceivers. As a general rule, close the cabinet door when a radio device is used:
- Transceivers that have 3 W of output power or less should be at least 1 m away.
Transceivers 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.
IMPORTANT
To comply with EMC standards, mount three ferrite cores (A1190MN or A1193MN) on
each of the FG, power, network and RS-232C cables.
