Top panel has terminal screw block for PWR1 and PWR2 input as well as Alarm
Relay output, alternate DC5V power jack and M3 grounding screw.
Alarm Relay Wiring
The alarm relay is closed during normal operation. If a fault is
encountered (like power supply input lost) then relay contacts
open until fault is remedied
Power input wiring
There are two independent and redundant power inputs,
marked PWR1 and PWR2. Observe voltage polarity when
wiring power to the screw block connector. Complete
wiring without hot wires and with screw block connector
disconnected from switch.
Installation Warning
Ensure proper electrical grounding availability before powering up device. The
unit should be grounded using either the M3 grounding screw or with the DIN rail
installation or wall mount brackets correctly grounded. Make sure power wires
have adequate gauge for the power required by the unit to avoid risk of wires
overheating and/or fire. This is especially important for the PoE PSE equipment.
As general rule, keep power wiring on a different path from data cables and avoid
crossing wires. This will reduce the risk of power surges on data ports.
