Compact Hardware Manual
•
Input power supply should be rated to at least 360 Watts of continuous power. Failure to use a properly rated
power supply may result in any or all of the following:
•
Power Supply damage
•
NT24k unit damage or sporadic operation
•
PoE ports powering down due to under voltage condition.
•
The NT24k can be configured to fault when either of the two supplies goes below a minimum voltage threshold.

Grounding
the
Unit
The grounding of any control system is an integral part of the design. The optimum noise immunity and emissions
are obtained when the NT24k chassis is connected to earth ground via a 12-14 gauge wire for the POE models
and 14-18 gauge drain wire for all other units. The NT24k units provide a ground lug or grounding point (see
illustrations) that is used to provide a safe grounding path of the device.
Compact Models
Note:
The NT24k power input (V-) pins are isolated from chassis ground. Do not attempt to ground
the switch to earth ground via the power input pins (V-).
Remarque:
La NT24k puissance d'entrée (V-) broches sont isolés de la masse du châssis. Ne pas
essayer pour mettre le commutateur à la terre via les broches d'entrée d'alimentation (V-).
