2 SITE LOCATION AND PROVIDING POWER
2.1 Mounting the Enclosure
2.1.1 Mount the enclosure in a location according to and compliant with local
electric code.
2.1.2 Mounting Tabs and screws are provided with the enclosure. The provided
screws are intended to be used to mount the tabs to the enclosure. User to
provide additional mounting hardware as needed.
2.1.3 Create knockout holes for any necessary power, current transformer and
communications lines in the bottom of the enclosure.
2.1.3.1 To maintain the warranty and integrity of the panel, all holes/punch
outs for conduit and wires should only be drilled in the bottom of the
enclosure and properly sealed to prevent exposure to moisture.
2.1.3.2 To prevent interference, it is recommended that sense voltage and CT
wiring are separated and run through different knock outs.
2.1.4 The enclosure does have the ability to be padlocked externally. This is
recommended to maintain security and device integrity.

2 SITE LOCATION AND PROVIDING POWER
2.2 Connecting Input Power
2.2.1 Per local electrical code and site specifications connect power to voltage
sense input and panel power input.
2.2.2 There are separate power inputs for meter reference voltage and panel power
to allow the hub and meter to remain powered if the circuits being monitored
need to be off.
2.3 Connecting Current Transformers
2.3.1 CT inputs are located next to the power input section on the lower DIN rail.
2.3.2 CT should be wired per manufacturer directions indicated below. CT terminals
are clearly labeled CT1 (X1/X2), CT2 (X1/X2), and CT3 (X1/X2).

The following describes these components and outlines basic installation instructions.
3.2 Phoenix Contact Power Supply
Description: The Phoenix Power Supply provides DC power to the components within
the cabinet, and, if needed, external devices that you may wish to power. There are no
installation steps required, however the following are some product details.
3.2.1 Model Number: STEP-PS/277AC/24DC/3.5 - 2904945
3.2.2 Nominal Input Voltage Range: 100 VAC – 277 VAC
3.2.3 Nominal Output Voltage: 24 VDC
3.2.4 Nominal Output Current: 3.5A
3.3 Leviton 4DUMR Power Meter
Description: The Leviton 4DUMR is a revenue grade, bi-directional, power meter that
provides information about the electrical performance of the monitored circuit.
Configuration of the meter assumes that the meter has arrived with factory default
settings. In the steps below you will: Set up communication parameters, voltage and
current information, and system information. All of this can be done with the push buttons
on the meter.
Important: Note now whether you have Split Core or Rogowski “Rope” CT as it will
alter the steps that follow.
