It is not advisable to instal the device in the following cases: if any device part is missing or the device is damaged or de- formed. In case of improper functioning Relay output terminals of the device contact the producer. (11, 12, 14) ver. 0.4.2 2006.06.20 11:00MOUNTING, FUNCTIONING CONNECTING WARNING 1.
