6.3. Power connection
PSW-11 is connected to an AC source of 220V. The supply cable is brought
into the unit through the cable gland, where it is connected to the terminal block
of the power supply unit.
IMPORTANT!
Grounding of the device is required. The ground resistance
must be no more than 4 ohms.
IMPORTANT!
Do not allow circuit boards touching high voltage live wires.
Failure in this case entails a loss of product warranty.
IMPORTANT!
Since the switch contains switch-mode power supplies, it is a reactive load.
During start-up, when charging input capacitors, a starting current appears and
it exceeds the nominal value. In order to avoid false alarms of the protection
devices, it is recommended to choose models with the characteristic C for a
current of at least 4A.
6.4. Connection of video cameras
The camera is connected to the switch using a twisted pair. It is recommended
to use a 4-pair shielded cable no worse than Category 5. When using the
TFortis TH camera housings, data transfer, powering video camera and
camera housing will be carried out by one cable, which eliminates the need to
use additional power cables.
