Tests prior to switching on voltage
Attention!
Prior to commissioning, all tests as indicated by the national regula-
tions have to be executed. In addition, it is mandatory that the proper
functioning of the operating device in accordance with this user man-
ual and all other applicable regulation has been executed.
Attention!
Incorrect installation and operation of the camera may lead to a loss of
warranty!
Attention!
When powering the camera on in ambient temperatures less then 0°C
(storage temperature) make sure to heat up the enclosure before
switching on the camera circuit. For non-continuous systems please
use an adequate time relay to switch on the heater, before the camera
circuit is switched on!
