PANELS & INSTALLATION
2.5 Power & Alarm
IFS/IGS
Series uses a removable terminal block for connection of DC power and Alarm. This device supports dual
input from two different DC power sources so that in the event of a single source failure, the
IFS/IGS
device will
continue to function normally.

The two power connections are shown in the above graphic. The device has clearly printed on the case the
locations of the two power inputs, their DC polarity as well as the alarm connection. The single electrical relay can be
wired into an alarm circuit and under normal condition it is connected as Normally Closed (will open upon alarm
condition). The alarm conditions include power failure and port link up/down and are user programmable through
Web user interface. See
in SNMP for more information on configuring alarm relay and triggering
fault events. Please note that the alarm relay contact can only support 1A current at 24VDC. Do not apply voltage and
current that exceed these specifications.
2.6 Earth Ground Connection
A separate 'Earth' grounding terminal is provided on the top mental palate for safety grounding of the
IFS/IGS
Series
. It is highly recommended that a stable ground be attached to this device so that any surges on power or via
LAN ports can be properly and safely shunted to ground. Follow steps below to install ground wire:
Step 1.
Prepare one suitable ground screw and one grounding cable.
Step 2.
Attach the grounding screw to the ring terminal of the grounding cable. Make sure that the grounding cable is
long enough to reach the earth.
Step 3.
Use a screwdriver (or other tools) to fasten the grounding screw on the earth ground hole securely.
