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
become open until fault is remedied
Power input wiring
There are two independent and redundant power inputs,
marked PWR1 and PWR2. Please observe voltage polarity
when wiring power to the screw block connector. Please
complete wiring without hot wires and with screw block
connector disconnected from switch.
Installation Warning
Please make sure of proper electrical grounding availability before powering
up device. The unit should be grounded using either the M3 grounding screw
or making sure the DIN rail installation or wall mount brackets are correctly
grounded. Make sure power wires have adequate gauge for the power required by
the unit to avoid risk of wires overheating and any risk of fire. This is especially
important for the PoE PSE equipment. As general rule, please 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.
