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 cellular-
host 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 Page 2
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.

Site Preparation
The 5068-050 Mounting Frame must first be installed on the utility pole. Power from the utility pole is wired into the Power
Disconnect Box. Existing wires from the 5068-050 are then connected to the EVSE via the nipple on the top of the Power
Disconnect Box. If the 3704 charger will not be installed right away, the top nipple should be sealed to prevent water
(rain/snow) from entering the Disconnect Box. If an optional RFID Reader is being installed, conduit needs to be run from the
Reader to the Reader Access Tab on the bottom of the 5068-050.
