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).

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.
