5.2. Power supply connection
PSW-1-45-WiFi switch is connected to 220V AC power supply. Power
supply cable is pulled into the unit trough a cable gland and is connected to
the power supply terminal block either directly or via a circuit breaker
assembly.
WARNING!
Grounding of the switch is required. Grounding resistance
should not exceed 4 Ohm.
WARNING!
Energized high-voltage conductors should never be in contact
with circuit boards. The resulting failure will lead to loss of product
warranty.
WARNING!
The switch contains static power supply units and, therefore, is a reactive
load. Inrush currents that occur during charging of the input capacitors will
exceed nominal current values. To prevent false tripping of the circuit
breakers, it is recommended to choose models with characteristic C and at
least 4A current.
5.3. Connecting the cameras and access point
It is recommended to use a 4-pair shielded cable, at least category 5.
Ethernet cable is pulled into the switch through a cable gland, clamped and
connected to RJ45 ports. For more convenient clamping, a cable gland
may be removed and then re-installed. Unused cable glands should be
sealed off.
