Introduction to Model 3704-A04XX EVSE Unit
The Model 3704 Electric Vehicle Supply Equipment (EVSE) is a 7.2 KW pole-mounted EVSE with Auto CoilTM cable
management retraction, capable of providing up to 30A at 208-240VAC, single phase, 50 or 60 Hz. This unit complies with the
SAE J1772 specifications for supplying electrical power to a J1772-compatible Electric Vehicle (EV). The Model 3704
conveniently coils the 25-foot cable internally when not in use. The model 3704 is capable of being controlled remotely to
apply, reduce or disconnect power to the electric vehicle, and can, with an optional EUMD installed, measure both voltage
and current being supplied to the EV. The 3704 can be equipped with an optional internal Gateway Module with a cellularhost connection and an optional Zigbee Module. Five status lights clearly indicate the state of the charging operation.
Safety Features
Tamper Resistent - The J1772 power cord and connector are locked mechanically in the storage position.
Extension - The cable initially lowers to an ADA height, and by pressing the switch on the J1772 connector, the
cable to driven out to the desired length.
Jam Resistent - If you pull the charging cable while it is retracting or if the cable gets caught on anything, cable
retraction will stop. The cable will make one additional attempt to retract. Thereafter, pressing and
releasing the switch on the J1772 connector (Figure 18) will restart the cable retraction process.
Spark Resistent - Electrical power is not applied to the power connector until the J1772 connector is fully inserted into
the power inlet on the Electric Vehicle and communication between the vehicle and charger has been
established. When the switch is pressed on the J1772 connector, voltage is removed.
Shock Resistent - The Model 3704 EVSE is equipped with a Ground Fault Circuit Interrupter (GFCI) which will disconnect
the electrical voltage from the power cord and connector, should current leakage to ground exceed
20 mA. The GFCI circuit is automatically tested at the start of each charge sequence. The GFCI will
attempt three re-closures to see the ground fault cleared before reporting a problem.
Over Current - The Model 3704 EVSE, when in use, continuously monitors the current being delivered to the EV.
Should the current exceed 32A for 15 seconds, the Model 3704 EVSE will disconnect the power to the
EV before the breaker trips. After disconnecting, the 3704 will auto-reset.
Low-Line - The source voltage to the Model 3704 EVSE is continuously monitored while in use. Should the voltage
drop below 180 VAC, the EVSE will disconnect the voltage to the EV to prevent damage to the EV’s
electronic circuits. When the voltage returns to above 200 VAC, the power will be restored to the EV.
Cold Load Start – If power fails while the Model 3704 EVSE is connected and charging an EV, charging will automatically
resume when power is restored. No user intervention is required. The charging will however, be
randomly delayed from 2 to 5 minutes to prevent the power grid from incurring a large power surge.
Plug-Out Detection - The model 3704 EVSE is equipped with a Plug Out Detection circuit that identifies when the connector
is attached to the electric vehicle. This allows the EVSE to immediately remove electric power from the
electric vehicle before the connector is totally removed from the vehicle inlet.
Disconnect Switch - The 5068-050 Mounting Frame, used to mount the 3704, is equipped with a disconnect switch for
locally shutting off power in the event the unit needs to be serviced or inspected.
Communication Options
An optional Gateway Module with a cellular-host connection is installed internally to facilitate two-way communication with
the host network. The 3704 communicates to the internal Gateway directly, or multiple chargers can use Zigbee to talk to
one charger/Gateway. ZigBee networks are secured by 128-bit symmetric encryption keys, so security is assured.
3704-IG-A04xx Installation and User Manual May 20, 2019 Page 1
Page 8
The Gateway Module then connects to an external network via a Cellular modem. The Cellular modem securely transmits
encrypted payment data to and receives authorizations from external PCI-compliant processors. Communication can also link
the EVSE network with third-party network management providers for reporting and call center support.
Additional Options
The Data Router (Figure 8) in the charger can be used in conjunction with a 3790-005 remote RFID reader, and can
accommodate a Fob or club-type card. Operation can also be initiated with an optional QR Code application on a cellphone.

Dip Switch Settings
The Model 3704 is equipped with an 8-position dip switch on the Data Router (Figure 15), to personalize each installation.
Switch 1 allows selectable pull-in force: SW1 OFF = ~15lbs., SW1 ON (Default) = ~25lbs.
Switch 2 is not currently used and is reserved for future applications.
Switch 3 puts the EVSE into Test Mode for connecting to a Payment Module via a ZigBee network. See the 3725-UG-002
Payment Module User Guide for information about adding the 3704 to the network. OFF = Not in Test Mode; ON = In Test
Mode
Switch 4 provides an interface for Control Access Security Systems (CASS).
Switch 5 is not currently used and is reserved for future applications.
Switch 6 puts the 3704 into learning mode to determine the initial lowering height of the J1772 cable for ADA compliance (48
inches). When ON, press the switch on the J1772 to extend the cable to the proper height, then set the switch back to OFF.
The initial lowered height is locked into the 3704.
Switch 7 sets the amount of time the user has to engage the J1772 connector after authorization. In the case where a
payment module is not used and the 3704 ON button is the actuation mechanism, the default OFF setting of this switch
allows the user one minute to engage the J1772 connector in the vehicle. In the situation where authorization via a payment
module is required prior to the initiation of charging, the ON position for Switch 7 allows a 15 minutes timeout for the
authorization. In other words, if the J1772 plug is not engaged in 15 minutes, a new authorization must be obtained. This
allows the user time to walk from the payment module, which might located some distance from the 3704, to the vehicle to
plug in the connector.
Switch 8 is used to select the breaker size when two 3704s share a circuit breaker. When the switch is OFF to select an
installed 40A breaker, the maximum current delivered to each vehicle is limited to 16A. If only one vehicle is connected, it
can draw up to the full 30A. When the switch is ON to select an installed 50A breaker, the maximum current delivered to
each vehicle is limited to 20A. Again, if only one vehicle is charging, it can draw up to the full 30A.

Operation
1. Open the lid to your electric vehicle’s (EV) charging receptacle.
2. Look up and observe the Data Router on the bottom of the EVSE (Figure 16). The blue Power LED is on.
Figure 16
3. Click your Fob, or if you are using the QR Reader, place the QR Code on your cellphone over the QR code on the
placard (Figure 17) on the utility pole. If you are using the RFID Reader, place your card/badge over the symbol on
the RFID Reader. The yellow Connect LED will start blinking and the cable will lower to the 48-inch ADA height.
(QR Code) (RFID)
Figure 17
4. Press and hold the switch on the J1772 connector (Figure 18), walk the charging cable to your EV, and plug the
J1772 connector into the charging receptacle. The yellow Connected LED turns off and the green Charging LED
begins flashing. Your EV’s battery is now charging.
5. The green Charging LED turns solid when the EV’s battery is fully charged. When charging is complete, disconnect
the J1772 connector from the EV’s charging receptacle by pressing the switch on top of the charging connector and
pulling it out. The green Charging LED turns off. The yellow Connect LED blinks until the cable is fully retracted and
then turns off. Only the blue Power LED remains on.
6. The cable will retract automatically when removed from the EV’s charging receptacle. If you pull the charging cable
while it is retracting or if the cable gets caught on anything, cable retraction will stop for safety reasons. The cable
will make one additional attempt to retract. Thereafter, pressing and releasing the switch on the J1772 connector
(Figure 18) will restart the cable retraction process. If this is the one hundredth time the cable has been extended
for charging, the built-in Cable Maintenance Program will automatically extend the cable to its full 25-foot length
and then fully retract it back up into the EVSE when the cable is unplugged from the EV.
NOTE: If you remove the charging cable from the EV’s receptacle before the battery is fully charged, the charging process
terminates, and the cable begins to retract. (Power is removed from the connector prior to its full removal from the
receptacle as a safety precaution.) Let the cable fully retract and restart the process. Retraction will take up to 20
seconds.
Built-in Safety: When power is applied to the EV, the EVSE monitors the current being drawn. Should the current exceed the
3704-IG-A04xx Installation and User Manual Page 16
maximum levels set by the breaker switches, the EVSE will disconnect the power from the EV and the red
Problem LED will turn on. If there was a ground fault, the EVSE will attempt three closures after a short
delay. There is no re-closure with an over-current trip.

Testing and Fault Modes
With the communications required between the EVSE and the electric vehicle, it is recommended that the installer use a
Control Module Inc. Model 3840-001 hand-held tester. This will thoroughly check out the EVSE, before using an Electric
Vehicle.
The primary function of the Data Router (Figure 19) is to display its operational status. The unit is equipped with five status
LEDs:
Blue (Power): Indicates primary power is applied.
Yellow (Connect): When EVSE is ready to charge the car, it starts blinking, indicating the cable is ready to be connected.
Once plugged into the car, it shuts off.
Green (Charging): After plugging the J1772 connector into the car it starts blinking, indicating the car is charging. Once
the car is fully charged, it turns on solid.
Red (Problem): Indicates a problem has occurred. (Refer to the Status Indicator Chart, on page 18).
Orange (Reserved): When lit, the EVSE has been reserved for use by another vehicle.
See the Status Indicator chart on the following page for complete status details.
