NTI ENTERPRISE ENVIRONMENT MONITORING SYSTEM
22
The E-5D-48V is available with connections for a 18~72VDC (24 or 48VDC nominal) user-supplied power supply. This is
typically used when the ENVIROMUX is installed in a Telecom environment. The E-5D-48V will accept a DC power source with
positive or negative polarity. A removable 3-pole screw terminal is provided for easy connection. The image below shows an E-
5D-48VDP, which has dual 18-72VDC power connections for a dual power supply option.
For your convenience, the power jacks for connecting and AC adapter are also provided, and may be used as well. These jacks
will accept 9-12VDC (9VDC 3A power supply may be purchased separately-order PWR-SPLY-9V3A). All power connections can
be used simultaneously without damage to the ENVIROMUX.

Note: The power supply monitor on the sensor summary page will only display the status of the 18-72VDC connections.
The 9-12VDC power connections will be ignored on the E-5D-48V(DP) models.
