1.0 Introduction
The Power Meter from Setra is a networked revenue grade power meter built on a versatile
and powerful platform designed to meet the high demands for any submetering application.
Available in a 3, 12 or 48 load congurations, the meter enclosure & intuitive web portal
interface signicantly reduce installation time and cost per metering point. The Power
Meter 12 & 48 load meters come standard with dual voltage inputs, and all versions are eld
congurable for use of standard or Rogowski style current transformers, enabling safe and
accurate measurement of both low and high amperage services.
The Setra Power Meter can be ordered in the following congurations, which are identiable
on the part number label.

1.1 Web Portal meter setup & conguration
Setup is both intuitive and time-saving through the Setra Power Meter Web Portal. The software
can be easily accessed through the meter itself, either through simple USB connection to your
PC or through Ethernet connection over a shared network.
1.2 Field selectable communication
Integration with building automation systems is made easy through eld selectable BACnet
and Modbus communication protocols. The meter’s communications interface is enabled
through either an EIA-485 serial connection (BACnet MS/TP or Modbus RTU) or over
Ethernet (BACnet/IP of or Modbus TCP). Along with these advanced network communication
protocols, the Setra Power Meter offers a connection interface with adjacent equipment
through one congurable pulse output and two congurable pulse inputs, enabling even more
data collection through the meter.
1.3 Intended use
Setra Power Meter is designed to closely monitor and provide detailed information of the
building and/or equipment. The meter can be used in varying capacities, measuring varying
loads with up to two different voltage reference points. Typical applications include measuring
power of buildings, leased building space, large machinery or equipment, lighting loads, and
more.
The meter will monitor and provide visual indicators on the Backlit Display, Error Indication
LED and Power Indication LED.
Each Power Meter comes standard with eld selectable BACnet and Modbus communication
protocols. The communications interface is through either an EIA-485 serial connection
(BACnet MS/TP or Modbus RTU) or over Ethernet (BACnet/IP or Modbus TCP). Along with
these advanced network communication protocols, the Power Meter offers one congurable
pulse output and two congurable pulse inputs, enabling more data collection at the meter.

of the meter, found on the main assembly. Simultaneously, lift the front housing off the stillassembled main assembly and back housing.
2. Next, remove the main assembly from back housing by flexing the rear housing away from
the main assembly using a flat screwdriver where indicated on the rear housing. This will
release the locking mechanism. Now, pull delete out the main assembly, rotating from the top.

3. To reassemble, rst, insert the bottom of the Main Assembly into the Back Housing and
rotate the top of the main assembly into position, connecting high voltage and accompanied
by a "click" to ensure the assembly is in place.

48 Load Meter shown below:
4. Attach the front housing by tilting the cover such that the bottom makes contact with the
Main Assembly rst, locking in the two securement tabs. Once the tabs are resting in their
respective securement slots, rotate and push the top of the cover onto the Back Housing and
Main assembly.

4.0 Planning for installation
Meter installation often includes coordination between individuals or groups of people with
different responsibilities. Spend a few minutes considering who will be executing each portion
of the installation and what tools are needed at each stage. Things to consider include
determining how to communicate with the meter, setting address conguration, access to
passwords, etc. The more tasks completed before installation means less time in the eld. The
following section gives an overview of these activities followed by details in the next section.
4.1 Meter conguration overview
Work performed ahead of the installation saves time in the eld and allows
a more streamlined installation. Typically performed at the workstation with
a computer.

5.0 Changing Conduit Position
The Setra power meter can support various applications via rotatable display to allow the user
to mount in any conguration, without impacting the user interface experience.
To rotate the orientation of the display, remove the front housing cover and slide the display
module along the main assembly, toward the bottom of the meter. Once it becomes dislodged,
simply rotate the display to the desired orientation and slide again toward the top of the meter.
Ensure the meter is de-energized prior to changing orientation.

6.0 Meter conguration
The following section illustrates the recommended installation of 12-load Power Meter. The
3-load and 48-load meter are slightly different but can follow the same procedure.
1. Remove all packaging material and separate the housing from the other components.
2. Locate a flat, clean portion of wall space for mounting. Decide meter orientation.
3. Remove main assembly for back housing by depressing the tab on the top of the meter, to
release the locking mechanism.
4. Locate, mark, level, and drill wall mounting points. The plastic back cover can be used as
a template for marking the drill locations on the wall. Using the four #8-15 x 5/8 screws
provided, fasten the housing to the wall.
Notes
1
If mounting on masonry wall, use the four blue Topcon screws provided. The
correct masonry drill size for these screws is 5/32 inch diameter
2
If mounting on drywall, use the four plastic drywall anchors in addition to the
#8-15 x 5/8 screws provided.
3
To avoid damage to the housing desired knockouts should be removed prior
to mounting on the wall

7.0 Connecting high voltage inputs
DANGER- Failure to follow these instructions will result in death or serious injury.
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
• Apply appropriate personal protective equipment (PPE) and follow safe electrical work
practices. See NFPA 70E.
• This equipment must only be installed and serviced by qualied electrical personnel.
• Turn off all power supplying this equipment before working on or inside equipment.
• The meters voltage leads (L1, L2, L3, and N, as necessary) must be connected to a
dedicated disconnect or a properly rated (15A) breaker.
• A voltage lead of 14 AWG THHN minimum 600VAC rating or equivalent is required.
• Wiring to these terminal blocks shall be tightened to 3.54 lb.-in torque.
• DO NOT EXCEED 347V Line to Neutral or 600V line to line. This meter is equipped to
monitor loads up to 347V L-N. Exceeding this voltage will cause damage to the meter
and danger to the user. Always use a Potential Transformer (PT) for voltages in excess of
347V L-N or 600V line to line. The Setra Power Meters are 600V Over Voltage Category
III device.
• When using rigid conduit, connect the hub to the conduit before connecting to power
meter enclosure.
• All unused conduit openings need to be closed using Setra provided conduit plug.
IMPORTANT- Verify the circuit breaker is marked as the disconnected breaker for the meter.
Setra Power Meter’s high voltage inputs must be connected through properly rated (15 Amp)
disconnects or breakers that disconnect all line wires so that they can be powered down. Each
disconnect or breaker must be located within easy reach of the meter operator and must be
labeled to indicate which set of device inputs it supplies power to. One disconnects is required
for each voltage input. The disconnect device or devices must meet IEC 60947-1, IEC 609473 and/or comply with the local electrical code.
Connection to the mains terminals shall be made with 14 AWG (1.63 mm) minimal wire gauge
THHN 600VAC rating. All high voltage input wires shall be routed through the high voltage
conduit entry and do not mix with other low voltage wiring. Any unused high voltage conduit
holes shall be plugged securely with supplied “safety cap”. Wiring to these terminal blocks
shall be tightened to 3.54 lb.-in torque.
Please note that there are two voltage inputs (Vin1 and Vin2) for 12-load and 48-load power
meter but only one voltage input (Vin1) for 3-load power meter. Each voltage inputs contain
up to four leads, namely L1, L2, L3, and N (neutral) which can be congured by software to
measure up to three phases voltage signal with respect to N (neutral). Vin1 L1 and L2 are also
connected to meter’s 80-600V wide input power supply to power the meter. When installing
a 12 or 48 load power meter, Vin 1 must be used to power the unit. The meter will not power
off of Vin 2.
