4.1 Overview of operation planning
SICLOCK TC 400 has been designed for weather-protected, stationary operation
in an industrial environment.
The operating conditions surpass the requirements according to DIN IEC 60721-
3-3:
• Class 3M3 (mechanical requirements)
• Class 3K3 (climatic requirements)
General information about operation
Avoid extreme ambient conditions. Protect your device against dust, moisture and
heat. For further information, see Chapter Technical Data (Section 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 forms
on or in the device. This also applies if the device is subjected to extreme changes
in temperature.
Commissioning
Allow the device to slowly adjust to room temperature before commissioning. Do
not place the device near heat radiation. With large differences in temperature,
harmful condensation can be avoided by leaving the device in the transport pack-
aging.
If condensation occurs, wait at least about 12 hours before you switch on the
device (for 20° C temperature difference). The waiting period is extended accord-
ingly for greater temperature differences.
