SensorMate Overview
The OutSmart SensorMate is an accessory of the OutSmart Monitoring System. It allows off-theshelf sensors such as current transformers to be used in the system. SensorMates connect to the
system through the OutSmart LoadRunner. Multiple SensorMates can be daisy-chained together.
For each SensorMate added to a LoadRunner the max number of EnergyMates that can be
connected to that LoadRunner is reduced by one.

Safety
DANGER — HIGH VOLTAGE HAZARD
WARNING - These installation/servicing instructions are for use by
qualified personnel only. To avoid electrical shock, do not perform any
servicing unless you are qualified to do so.
Only qualified personnel or electricians should install the OutSmart
SensorMate.
The OutSmart SensorMate is intended to be used in accordance with this
manual and all safety instructions must be followed.
All wiring in the United States must be installed in accordance with the latest adopted edition
of the National Electrical Code (ANSI/NFPA 70, NEC) and state or local requirements.
It is recommended that a licensed electrician install the OutSmart SensorMate.
It is recommended that the OutSmart SensorMate be installed either in an electrical enclosure
(panel or junction box) or in a limited access electrical room.
Ensure that the line voltage inputs to the OutSmart SensorMate have either fuses or circuit
breakers on each phase (not the neutral or ground wires). To disconnect the OutSmart
monitoring system remove fuses or shut off breakers that the line voltage inputs are connected
to. Equipment must be disconnected from the HAZARDOUS LIVE voltage before access. In case
“I” to “O”) the breakers or remove the fuses the line
of hazard turn off (switch from
voltage inputs are connected to.

General description
The SensorMate is a device that allows off-the-shelf current transformers to be added to the
OutSmart energy monitoring system. It can accept up to three current transformer inputs and 3
voltages with a neutral reference. Multiple SensorMates can be connected in series. A
maximum of 32 SensorMates can be connected to one OutSmart LoadRunner, or any
combination of SensorMates and EnergyMates up to a total of 32 devices.

SensorMate installation
The base housing of the SensorMate is a standard 4” X 4” X 2” work box. Remove the two
screws holding the top of the SensorMate to the base housing. Mount the base housing as you
would a typical 4X4 work box. It can be screwed directly to a rigid surface such as a concrete
or ¾” plywood. The SensorMate housing should be mounted in accordance with local and
national electrical codes.
The SensorMate is connected to the OutSmart LoadRunner by a 4 conductor phone cable. The
cable is to be run in conduit.
Current transformers are to be mounted in accordance with the instructions supplied by the
current transformer manufacturer. Leads from the current transformers to the SensorMate
should not be accessible to users or operators, and if necessary should be run in conduit.
Line voltage is brought to the SensorMate for each of the lines being monitored. A neutral or
ground reference voltage is brought to the SensorMate. The Wires are to be installed and run in
accordance with local and national electrical codes.
Ground is to be attached to the work box. Ground is then brought to the ground terminal on
the PCB ONLY when attached to a delta wired circuit (no neutral present). DO NOT bring
ground to the PCB when neutral is present. Ground is used as a voltage reference for delta
wired circuits. The SensorMate cover is to be installed with a #8 washer and #8 lock-washer.
The washer goes under the head of the screw, the lock-washer goes between the washer and
the SensorMate cover. This is needed to maintain the ground connection between the
SensorMate cover and the work box.
Tightening torque for field connections: 4.5 to 6 inch-lbs
System functionality check
To determine system functionality you must first reenergize the circuits that are being
monitored. Turn the breakers back on that were shut off during installation. If the breakers
remain on and don’t trip the first level of functionality has been achieved. The final functional
check is done by the system software. The system setup procedure is run. During this setup
procedure all devices that have been added to the system will be identified. If a SensorMate, is
not located by the system software then it is either a non-functioning unit or it was not
properly installed.

Current Transformer installation:

Current transformers (CT) to be mounted in accordance with local and national electric
codes.

CT to be installed in accordance with the installation instructions supplied with the CT.

The current rating of the CT to equal or exceed the rating of the breaker /fuse on the line
to be monitored by that CT.

CT to be secured to line with appropriate wire tie device.

CT should always to be mounted on a wire, inside of a metal box with appropriate UL
ratings.

Lead wires from CT to be run to SensorMate inside appropriate enclosure or UL recognized
conduit.

Label side of CT should face towards the expected source of power. (Not a safety issue)

White lead from CT connects to positive CT terminal in SensorMate. (Not a safety issue)

Black lead from CT connects to negative CT terminal in SensorMate. (Not a safety issue)

CT leads to be secured with wire ties away from high voltage wires where possible and to
prevent the possibility of pinching wires when the box cover is installed.
