Note
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 purpose, the operating voltage is applied via a 1 kΩ se-
ries resistor for one hour. Please contact the SIEB & MEYER service department for de-
tails.
5.6.2
Installation and Operation
NOTICE
Damage of electrostatically sensitive components due to improper handling
→ Never touch electronic components..
The following requirements are to be considered for the installation and the operation
of the device. Noncompliance with theses requirements is regarded as
abnormal op-
erating condition
