“WARNING”: Make sure this equipment is correctly grounded. Failure to do so can cause
injury or damage equipment.
“CAUTION”: Electronic components are static sensitive. Use proper static precautions
(static straps) before working on the equipment.
“WARNING”: Failure to properly ground all equipment can cause injury or damage
equipment.
“WARNING”: Installation must comply with National Code (NFPA #70), Automotive and
Marine Service Code (NFPA #30A), Federal, State and local codes.
“CAUTION”: This equipment generates and uses radio frequency energy. If not installed
and used properly, i.e., in strict accordance with the instructions in this manual, it may cause
interference to radio communications. The console was tested and found to comply with the
limits for a Class-A computing device in accordance with Sub-part J of Part 15 of the FCC
Rules. A Class-A computing device is designed to provide reasonable protection against
interference when operated in commercial environment.
“CAUTION”: Follow proper grounding procedures to reduce radio frequency interference
(RFI). Ground each piece of equipment connected to, or controlled by, the console to the
electrical service panel ground.
“CAUTION”: Each dispenser must have a 12 gauge or larger green stranded ground wire
connected from the grounding lug of the junction box to the main electrical service panel
ground. (National Electrical Code, Article 514-7). It is unacceptable to rely on the conduit for
this grounding requirement.

System Requirements
In developing the Triangle MicroSystems control system for Bennett dispensers, Bennett provided the
communication protocols that required separate data wires for each dispenser. This is Bennett standard policy for
“third party” control systems. Secondly, the TMS control system does not require the Bennett interface box to
interface with the dispensers. The dispenser control data wires connect directly from the 3K-dispenser junction box
to the EZ 85 IC box. The data wires from the dispensers to the IC Box should be a shielded, single twisted pair
conductor to avoid electrical noise interfering with communication.
Installations will vary from site to site in terms of the electrical interference induced into the dispenser data wires. The
cable shield when connected to the ground screw on the TMS PetroSmart interface power supply will significantly
reduce the electrical interference.

Power Requirements
CONNECTION INSTRUCTIONS FOR THE SYSTEM POWER SUPPLY,
DISPENSER, MOTOR, AND ELECTRICAL GROUND CIRCUITS
A.C. POWER REQUIREMENTS
1. Breaker Panel: A 125 Amp breaker is the minimal allowable electrical service for the pump motor and
interface boxes, dispensers, canopy lights and advertising signs.
2. IC boxes: Both the dispenser IC box and the DPT credit card module IC box require a 115VAC, 15 Amp
DEDICATED breaker (with no other devices or outlets connected to it) for connection to the EZ TM85 board, and
to the MPC-TM85 board. Make sure the correct voltage and frequency are present. All AC wires must be 14
gauge (min.), and in conduit. Do not put wiring from other sources in this conduit.
3. PETROSMART EZ Console: a standard plug-in AC Adaptor power module powers the console. The Adaptor
can be inserted into a standard electrical outlet that supplies, 115VAC, 60Hz, and 15W power. The Adaptor
converts the input to 15 VDC, 600mA that it supplies to the EZ console. A UPS is supplied with then system to
minimize disruption in the event of a general power failure.
4. Dispensers: The dispensers' installation guide shows all requirements including, but not limited to breakers,
wires to supply data signals to the electronics, green wire for Earth Ground, and wires to power the dispenser and
fluorescent lighting. Refer to the installation manual for the dispenser being installed for complete installation
requirements.
Pump Motor: Use auxiliary relays, correct gauge wires, and 115/230VAC breakers to supply power to the pump
motors. Refer to the installation manual of the equipment being used for complete installation requirements,
drawings, and special notes for proper installation.
Pump Requirements
The Bennett 3K dispensers must have firmware equal to or better than 210 – 044.
It must be set to 485 communication, and each fueling point must be addressed in the pump’s CPU.
It DOES NOT need a pulser interface option to communicate with the console. The firmware at or above 210
allows the pump and console to “talk” back and forth about current pricing, preset / prepay sale amounts, handle
and sale status.
You may wish to connect only one set of data wires at a time to the EZ system. All of the dispensers will talk
basically over the same two wires. Polarity or other wiring issues at one pump may cause a system wide
communication failure.
Also, if two fueling points are set to the same address position, say # 2, the console will show communication with
fueling point 2, but will not be able to control the pump properly. Prices may be sent to one dispenser, but the
handle switch or grade select button may have no effect at the console as we will be receiving mixed messages.
One pump will reply that its handle switch is lifted while the other with the same fueling point # will reply that its
handle switch is hung up etc.

INSTALLING THE PETROSMART EZ CONSOLE
1. Mount all in Make sure that all system component connections and cables are properly assembled
before turning on the power to any of the components.
2. Interconnect boxes near the wire trough, or where the conduit from the pumps/dispensers enters
the building.
3. Place the console in a location that allows an unobstructed view of all fueling positions at the site.
Fig. 7. Back View of the PetroSmart EZ Console
Cable Connections
The connection between the PETROSMART EZ console and the interconnect box marked “DISPENSER
CONTROL” is made via a 25 foot round cable having 15-conductors and DB-15 type connectors. Connect this
cable at the connector marked PUMP CONTROL on the back of the EZ console to the connector labeled “2” on
the front pan of the dispenser IC Box.
Longer cables are available to fit the particular needs of the installation site. The maximum recommended
distance between the PETROSMART EZ Console and the PETROSMART EZ, “DISPENSER CONTROL”
interconnect box is 500 feet. Consult TMS for prices and availability.
A connection is made between the IC Box back pan to the front pan is made via a 3 foot round cable having 15-
conductors and DB-15 type connectors to the right most connection labeled “3” or the right most connection when
the door is closed.
Refer to the PetroSmart EZ console, programming/operators guide on how to program the console.

Important Notes:
1. TURNING THE SYSTEM OFF: It is not recommended or necessary to turn OFF the dedicated system breaker
that supplies power to the PETROSMART EZ IC boxes during the time the store/station is closed. Simply turning
the console OFF/ON key to the OFF position after all hoses have been de-authorized, along with following the
dispenser power down sequence, will prevent fuel from being dispensed.
2. All + and – data wire connections between the PETROSMART EZ IC boxes and the dispensers must be 18
gauge or larger.
3. All AC wires must be 14 gauge or larger.
4. Use cable ties to keep the data cable in place from the console to the interconnect box if conduit is not used.
5. If the PETROSMART EZ cable is put through a conduit, use 2" minimum to allow room for the connectors on the
cable. Do not cut connectors from the PETROSMART EZ cable to use smaller conduit. Do not put PETROSMART
EZ cable conduit underground. PETROSMART EZ data cables are not designed to operate under these conditions
and will not be covered under warranty.
6. Do not use wire nuts on any grounding connections. Make all connections with compression connectors (crimp
or split lug).
7. If the console or dispenser power comes from a sub-panel, all ground wires must end at the main electrical
service panel ground.
8. There must be no more than 1-ohm resistance between Neutral and Earth Ground.
9. Do not use old or used wire for dispenser wire connections.
10. Use rigid metal conduit only. Do not use PVC conduit.
1. 11. Do not route mercury vapor, canopy light wiring, or other unrelated wiring through the dispenser-wiring
conduit.
2. 12. Auxiliary relays or contactors MUST BE used in the motor circuit! Refer to the installation manual of the
dispenser for complete installation requirements, drawings, and special notes.
13. Wiring for dispensers, PETROSMART EZ for BENNETT IC box, and other control boxes should all be on the
same phase from the service panel, or erratic operation/communication could result.
14. In the interest of everyone's safety, all persons involved in the operation of this system should be made aware of
a proper power-down sequence for all components used to dispense flammable products.
