Random vibration: 0.31 g RMS at 50Hz to 500Hz, 10 minutes per axial direction.
When not operating: 2.46g RMS from 5Hz to 500Hz, 10 minutes per axial direction.
Installation (overvoltage) category
This product is powered by a main power supply conforming to installation (overvoltage)
category II.
Warning:
Ensure that no over-voltage (such as lightning) reaches the product. Otherwise,
operators may be exposed to electric shock.
Definition of install (overvoltage) category
Installation (overvoltage) class I is the signal level that applies to the measuring
terminal of the device connected to the source circuit, where measures have been
taken to limit the instantaneous voltage to a correspondingly low level.
Installation (overvoltage) class II refers to the local distribution level, which is applicable
to devices connected to the mains (AC power supply).
Degree of pollution
2 class
Definition of pollution level
Pollution Level 1: No pollution, or only dry non-conductive pollution. This level of
contamination has no effect. Examples: clean rooms or office with air conditioning.
Pollution level 2: Generally only dry non-conductive pollution occurs. Temporary
conduction due to condensation may sometimes occur. Examples: general indoor
