At start-up, the power supply must be capable of momentarily
sourcing at least twice the operating current. The Gateway may
draw significantly more current momentarily at start-up if not
limited by the power supply.
Power over Ethernet (PoE)
Gateway supports IEEE 802.11 PoE as a Powered Device (PD) on
either port.
Input and output connections
In: DC power (2-wire)
I/O: RS-485 (2-wire)
The Gateway is designed to be powered by 24 VDC (nominal) Class 2 supply and requires
350 mA of current per network.
The wiring should include an external power shut-off switch or circuit breaker positioned
near the Gateway.
The terminals on this connector can accommodate wires from 24 AWG to 12 AWG; 18
AWG wire is recommended. Tighten screws to 4.4 to 5.3 l bf-in (0.5 to 0.6 Nm).
In ambient temperatures greater than +60 °C, use wire rated for at least 5 °K above the
maximum ambient temperature.
Note
Using an uninterruptible power supply (UPS) is recommended to ensure availability during
power failure.
