Models
Applications
The SubMonitor Connect serves as a:
• Component motor protection relay (installed into a customer-provided NEMA 3R panel),
• Starter incorporated into a panel,
• Soft starter incorporated into a panel.
Component Models
The SubMonitor Connect component devices serve as a motor protection relay for pump systems. These
devices are installed into a customer’s existing NEMA 3R panel.
The MT1111 (American UL listed version) and MT6111 (European CE version) are each groundwater products
sold as an individual component. This Pump Protection Overload Relay monitors amperages from 1 A to
135 A. Currents up to 1000 A can be monitored with external current transformers (CTs). The Overload Relay
includes RS-485 Modbus communication, fault relay output, and PT100/PT1000 inputs. The model MT6111
Overload Relay is also compatible with SubTemp motor temperature sensors.
IMPORTANT: SubMonitor Connect is not compatible with variable frequency drives, electronic phase con-
verters, or solid state soft starters. These devices will cause nuisance tripping of the motor overheat fault, or
may cause damage to SubMonitor Connect components.
Reduced voltage starters may be used with the SubMonitor Connect if the starting time does not exceed 3
seconds. The motor must be up to full voltage in less than three seconds to prevent excessive wear on the
motor bearings, and also prevents the SubMonitor Connect from faulting. When the soft starter has the
motor up to full voltage, the soft starter must be switched out of the circuit (bypassed). Refer to, reduced
Voltage Starters in the Franklin Electric AIM manual for more information.
SMS & Soft Starter Panel Models
The SubMonitor Connect products installed in Franklin Electric Starter panels and Soft Starter panels are
advanced motor protection relays for pump systems, and have more features. There are two starter types:
one type using a Triac output, and one type using PWM output. This Pump Protection Relay monitors
amperages from 1 A to 135 A. Using external current transformers (CTs), it can monitor currents up to
1000 A.
The MT1311 is a full-featured SubMonitor Connect that is installed into the SMS and SMS-RV family of panels
rated for over 135 A.
The MT2211 is a full-featured SubMonitor Connect that is installed into the SMS and SMS-RV family of panels

Electrical Installation
Wiring Guidelines
Maintain proper clearances and verify that no possibility of an electrical short exists between the power
conductors or enclosure. Ensure that wires are not under stress and all insulation is intact.
All control wiring — sensors, switches, etc. — should be in a separate conduit routed individually, not
parallel, from high voltage wiring. Additionally, any shielded cables should be properly grounded.
High voltages capable of causing severe injury or death by electrical
shock are present in this unit.
• To reduce risk of electrical shock, disconnect power before working on or around the system. More
than one disconnect switch may be required to de-energize the equipment before servicing
• Make sure the panel’s ground terminal is connected to the motor, control enclosures, metal plumb-
ing, and other metal near the motor or cable using wire no smaller than motor cable wires.
• Install and wire in accordance with all applicable local and national electrical construction codes.

MT1111/MT6111: Route Motor Wires Through Sensors
For MT1311/MT2211, go to “Start-Up Programming” on page 15.
The SubMonitor Connect input power is connected at the terminal block on top of the device. The phase
order (relationship) to the motor must match the phase order to the power connection, i.e. connections
directly match to the phases that pass through the sensors:
L1-Phase A/T1 | L2-Phase B/T2 | L3-Phase C/T3.
Route the T1, T2, and T3 motor power leads
through the sensors in the SubMonitor Connect
from top (power side) to bottom (motor side).
IMPORTANT: The SubMonitor Connect has a
built in phase sequence meter. If upon initial
power up, the SubMonitor Connect displays a
Phase Reversal, Low Power Factor, Low Power,
or Negative Power fault, the incoming
voltages at L1, L2, and L3 terminals are in a
negative sequence (compared to the phase
sequence of the sensors), and the contactor is
locked out until the phase sequence is

High Current Installations using Current Transformers (CT)
High current installations (above 135 A) require the use of external Current Transformers (CT) for the
SubMonitor Connect to accurately monitor the motor current. Ground Fault protection is disabled when
using external current transformers.
1. Ensure that all system power is off. More than one
disconnect may be required.
2. Locate three identical turn ratio CTs. The turn ratio
(or transform ratio) is usually printed on the exterior
of each CT.
3. Run a (motor) wire from the Disconnect through the
center of a CT before connecting to the Contactor.
The arrow label on the CT points to the line side of
supplied power. Repeat for the other two wires.
NOTE: Current in the wires routed through the Sub-
Monitor Connect internal CT sensors shall not exceed
135 A. Use higher capacity CTs for motor wire current
exceeding 135 A to avoid a safety issue and/or prod-
uct damage.
4. Maintaining phase relationships, L1 to Phase A, L2 to
Phase B, and L3 to Phase C, route one of the two CT
wires through the SubMonitor Connect sensors.

5. Connect each CT wire to it’s other CT wire via the grounded terminal block (inset photo on previous
page).
CT Kits available:
• 5860015170 - SubMonitor Connect CT Kit, 120-270A
• 5860015180 - SubMonitor Connect CT Kit, 200-400A
• 5860015210 - SubMonitor Connect CT Kit, 320-720A
• 5860015190 - SubMonitor Connect CT Kit, 400-900A
When using CTs as part of the SubMonitor Connect system, be sure to program the SubMonitor Connect
appropriately. Refer to “Programming: Advanced Setup > Administration” on page 26 for External CT Ratio
setup, or make this setting using the FE Connect mobile app.
An example for CT use:
An installation is using 500:5 ratio CTs with 500 A on the power lines.
The SubMonitor Connect measures 5 A. The SubMonitor Connect resolution is 0.1 A, which equates to ±10 A
reading on the motor power lines. This means that the SubMonitor Connect reading difference can be
between 505 A and 495 A.
Refer to “Wiring Diagrams for Panels” on page 59 for schematics.
