each 3 shocks (in both directions of the 3 axes)
Continuous shock
IEC 60255-21-2, Class 1
IEC 60068-2-29

Standards: IEC 60255-6
Type tested (acc. to IEC 60068-2-1 and -2,
Test Bd for 16 h)
-25 °C to +85 °C or -13 °F to +185 °F
Permissible temporary operating temperature (tested for
96 h)
-20 °C to +70 °C or -4 °F to +158 °F
(legibility of display may be restricted from +131 °F (+55 °C))
Recommended for permanent operation (according to
IEC 60255-6)
-5 °C to +55 °C or 23 °F to +131 °F
when max. half of the inputs and outputs are subjected to the
max. permissible values
Limit Temperatures for Storage -25 °C to +55 °C or -13 °F to +131 °F
Limit Temperatures during Transport -25 °C to +70 °C or -13 °F to +158 °F
Storage and transport of the device with factory packaging!
1)
Limit temperature for normal operation
(i.e. output relays not energized)
-20 °C to +70 °C or -4 °F to +158 °F
1)
Limit temperature with maximum load
(max. cont. permissible input and output quantities)
-5 °C to +55 °C or -23 °F to +131
Admissible humidity Annual average ≤ 75 % relative humidity;
On 56 days of the year up to 93% relative humidity. Condensa-
tion must be avoided in operation!
It is recommended that all devices be installed so that they are not exposed to direct sunlight nor subject to large fluctua-
tions in temperature that may cause condensation to occur.
