2.3 Transport and Storage
Avoid improper mechanical load of the device. The following points must especially be
taken into consideration:
▶ Protect the device against mechanical damage (max. acceleration = 40 m/s²).
▶ Protect the device against dirt and humidity.
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.
▶ Storage in the open is not permitted.
▶ 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.
2.4 Installation
NOTICE
Damage of electrostatically sensitive components due to improper handling
Never touch electronic components.
Consider specific mounting instructions for your device.
Mechanic conditions for the system installation:
Vibrations must be within the following limits, if the CNC chassis is mounted in or to the
machine.
Frequency [Hz] Limits
2 Hz to 9 Hz max. 6 mm amplitude deflection
9 Hz to 25 Hz max. acceleration 10 m/s²
25 Hz to 150 Hz max. acceleration 5 m/s²
Tab. 1: Vibration limits of the system
The above data are related to horizontal movements by the servo amplifiers of the
series mounted in a 72 WU chassis. Depending on the device type and size of the
chassis smaller values are possible.
