When commencing installation make
sure that the specifications for the power
supply for the installation correspond with
those required by the device.
Do not power the product using auto-
transformers.
Check that the power supply socket and
cable are adequately dimensioned.
Nominal section of the cables used:

In the case of a direct current power
supply, the polarity of the voltage applied
to the power supply terminal is irrelevant.
To power the unit, use the power supply units
indicated in the technical data sheet of the product
on the website: www.videotec.com, or use a toroidal
transformer with nominal power of at least 200VA.
Connect the power supply cable to the relative
connector (J4, Fig. 19, page 24).
