4.1 Overview of operation planning
SICLOCK TC100 is designed for stationary use in weather-proof locations in an
industrial environment.
The operating conditions surpass the requirements of DIN IEC 60721-3-3.
• Class 3M3 (mechanical requirements)
• Class 3K3 (climatic requirements)
General notes on operation
Avoid extreme ambient conditions. Protect your device against dust, moisture and
heat. Refer to Technical data (Chapter 13).
Do not place the device in direct sunlight.
Caution
The device is approved for operation in closed rooms only. The guarantee is void
if this stipulation is ignored.
Condensation
When transporting the device at low temperatures, ensure that no moisture gets
on or into the device. This also applies if the device is subjected to extreme chan-
ges in temperature.
Commissioning
Allow the device to slowly adjust to room temperature before commissioning the
device. However, do not expose the device to direct heat radiation. In the event
of greater temperature differences, harmful condensation can be avoided by lea-
ving the device in its transport packaging.
If condensation develops, wait 12 hours before you switch on the device (for a
temperature difference of 20°C). For greater temperature differences, the waiting
time is correspondingly longer.
