Make sure that dust plugs are plugged on optical fiber connectors equipped with
them during transport of the device. Otherwise, recommissioning is potentially not
possible.
▶ Never touch electronic components.
The following climatic conditions apply to the storage. If required, appropriate meas‐
ures must be taken to ensure these climatic conditions (installation of heating/air condi‐
tioning systems etc.):
▶ The storage area must be clean (dust-free, if possible), dry and well-ventilated.
▶ No storage in the open.
▶ The storage temperature must be in the range of −25 °C to +55 °C (−13 °F to
+131 °F). Shortly it may be +70 °C (+158 °F).
▶ The relative humidity on the storage premises must be in the range of 5 % to 75 %
(no bedewing).
▶ Sudden changes of the temperature or the humidity should be prevented.
▶ Avoid stacking of the devices during transport and storage.
The maximum storage period is 2 years. Electrolytic capacitors produce high leakage
currents when a voltage is applied after a long storage period without applied voltage
and must be reformed. For this, the operating voltage is applied via a 1 kΩ series
resistor for one hour. Please contact the SIEB & MEYER service department for
details.
3.6 Installation
NOTICE
Damage of electrostatically sensitive components due to improper handling
Never touch electronic components.
Consider specific mounting instructions for your device.
Mechanical installation conditions for the system according to DIN EN 61800-2:
Vibrations must remain within the limit values of the IEC 60721-3-3, class 3M1,
standard for fixed equipment.
Frequency [Hz]
Amplitude [mm] Acceleration [m/s²]

Tab. 1: Vibration limits of the system
Vibrations which exceed these limits, or the use on mobile equipment, are considered
as abnormal mechanical conditions.
Operating conditions:
The following requirements are to be considered for the installation and the operation
of the device. Noncompliance with theses requirements is regarded as abnormal oper‐
ating condition:
▶ The device is conceived according to DIN EN 61800-1 / DIN EN 50178 for the dirt
level 2. That means: Ensure to avoid conductive impurities during the operation.
▶ Devices with air cooling only can be loaded to their maximum up to a height of
1000 m above MSL (3281 ft above MSL). For an operation in areas higher than
