Limit Temperatures for Storage
Limit Temperatures during Transport
Storage and transport of the device with factory packaging!
1)
Limit temperature for normal operation
(i.e. output relays not energized)
1)
Limit temperature with maximum load
(max. cont. permissible input and output quantities)
1)
UL–certified according to standard 508 (Industrial Control Equipment)
Humidity
Admissible humidity
It is recommended that all devices be installed so that they are not exposed to direct sunlight nor subject to large fluc-
tuations in temperature that may cause condensation to occur.
