Introduction to Model 3722-A30XX EVSE Unit
The Model 3722 Electric Vehicle Supply Equipment (EVSE) is a 7.2 KW ceiling-mounted EVSE with cable management
retraction, capable of providing up to 30A at 208-240VAC, single phase, 50 or 60Hz. This unit complies with the SAE J1772
specifications for supplying electrical power to a J1772 compatible Electric Vehicle (EV). The Model 3722 stores the power
cable safely out of reach and off the ground, eliminating a tripping hazard and tampering. When the Model 3722 is activated
by using either the separately mounted ON switch or via a separately mounted Payment/Gateway Module transaction, the
cable and connector lower to an ADA height where it can be easily reached and extended a maximum of 20 feet to the
Electric Vehicle power inlet by pressing and holding the switch on the J1772 connector (Figure 1).
The Model 3722 is comprised of the Electric Vehicle Supply Equipment (EVSE) with a motorized cable controller and the Data
Router, which is used to activate the EVSE (turning it on or off). There are a number of operating options that are compatible
with the Model 3722, ranging from simple ON switches, to a Data Router that displays kW’s used, the price per kW, and the
total sale cost. The operating option you select is included with the shipment of the EVSE unit.

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 19) 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 3722 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 3722 EVSE, when in use, continuously monitors the current being delivered to the EV.
Should the current exceed 32A for 15 seconds, the Model 3722 EVSE will disconnect the power to the
EV before the breaker trips. After disconnecting, the 3722 will auto-reset.
Low-Line - The source voltage to the Model 3722 EVSE is continuously monitored while in use. Should the voltage
drop below 180 VAC, the EVSE will disconnect the voltage from 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 3722 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 3722 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 3722 is equipped with an internal disconnect switch for locally shutting off power in the event the
unit needs to be serviced or inspected.
Payment Options
A Payment Module is used with the 3722 EVSE in fee-based electric vehicle charging environments to facilitate commercial
transactions. The 3725-104 Payment Module can be located on a pole, nearby on a wall, or mounted remotely from EVSE.
Refer to the 3725 User Manual and Installation Guide for more information about the Payment Module.
Note: A Gateway Module (Model 3727-200) can be used in place of the Payment Module when two-way communication is
required without payment functions. . Refer to the 3727 User Manual and Installation Guide for more information
about the Gateway Module.
Communication Options
There are two communication options available for facilitating communication between the EVSE and payment or gateway
systems:
Serial Connection
A serial connection can be established between one or more 3722 EVSEs and a Payment Module or Gateway. A single serial
Payment Module or Gateway can support from one to eight EVSEs, depending upon its configuration.

3722-IG-002 Installation and User Manual February 6, 2019
3
ZigBee Connection
The 3722 EVSE will also communicate to a Gateway or Payment Module using the ZigBee Mesh protocol, allowing wireless
connections. ZigBee networks are secured by 128-bit symmetric encryption keys, so security is assured. A single ZigBee
Payment Module or Gateway can support up to 32 remote EVSEs.
Remote Connection
Remote connections between 3722 EVSEs and a Payment Module can be made, typically using a ZigBee Mesh network. This
allows the EVSEs and Payment Module to be located a greater distance from each other, and also a greater number of EVSEs
to work with a single Payment Module. (See chart below).

NOTE: Administrative data can be transmitted to a remote laptop computer (via the Gateway with a ZigBee Mesh network -
option only) without accessing an external network.
Additional Options
Data Router: The Data Router (Figure 18) in the charger is supplied with a basic ON/OFF keyboard for either free use, or use
in conjunction with an optional Payment or Gateway Module. The charger can also be equipped with a Data
Router with an optional Handbook 44-compliant display module to display Kilowatts (kW) (Figure 18A) used
and the associated cost.
EUMD: The Handbook 44-compliant Data Router displays the data collected by an EUMD Module (End-User
Measurement Device), which is an internal revenue-grade meter that measures power dispersed to the vehicle
during a session with 1% or better accuracy. The EUMD can also be installed and used by itself to send power
measurements back to the host.
Remote Fob:An external module can be purchased that receives RF signals from a remote fob to lower the EVSE J1772
power cable, operating the same as the wall-mounted ON switch.
Power: With the addition of an internal jumper plug, the 3722 can be set up for use with a 20A breaker, reducing
maximum charge current to 16A.

Site Preparation
The Model 3722 (Figure 2) is a single EVSE unit designed to be mounted to a garage ceiling in a horizontal position. Power
must be located at the charging location and supplied by an individual, dedicated 40A non-GFCI circuit breaker at the breaker
panel. A qualified electrician or installer should provide local power at the charging site, install conduit back to the main
breaker panel and make final wiring connections for power at the breaker panel.
Dimensions
Figure 2

3722-IG-002 Installation and User Manual February 6, 2019

Site Selection
The Model 3722 was designed to be mounted to the ceiling and should be positioned, if possible, so that when the J1772
power connector is lowered, it will be close to the power inlet on the electric vehicle. This location is recommended because
the cable, when extended, has a 20 ft. reach (Figure 3), easily reaching the front, rear or side of the Electric Vehicle being
serviced. It is also recommended that the cable lowers between vehicles to make it easier to access the power inlet and
prevent the power connector from hitting the vehicle(s).
Figure 3

3722-IG-002 Installation and User Manual February 6, 2019

Mounting the Unistruts to the Ceiling
The Unistruts used in this installation are not supplied in the kit. They can be purchased at any reputable building supply
source. Two pieces are required with a minimum length of 23 inches.
CAUTION:
The mounting of the two Unistrut sections must be secured to a solid structure (such as the ceiling
joists) using appropriate fasteners and must be level. Do not use hollow wall anchors. The EVSE
unit weighs 42 lbs. (plus the Unistruts and attaching hardware). Serious injury or death can result if
the EVSE unit falls onto personnel during installation or operation.
ATTENTION:
Le montage des 2 Unistrut sections doit être sécurisé une structure solide (comme les solives de
plafond) à l'aide de fixations appropriées. N'utilisez pas les ancres de mur creux. L'unité EVSE pèse
42 lbs (ainsi que le Unistruts et y attacher le matériel). Des blessures graves ou décès peut se
produire si l'unité EVSE tombe sur le personnel pendant l'installation ou de la conduite.
1. Use the 3722’s ceiling mount plate (Figure 7B), which has identification labels on it, to identify where AC power
needs to be brought in and where the J1772 connector will be lowered from. Then determine the location to install
the Unistruts.
2. Layout an appropriate hole pattern on the ceiling according to the dimensions in Figure 2. Drill pilot holes if
necessary.
3. Secure the two Unistrut sections to the ceiling using appropriate hardware (not included). The recommended
concrete fastener is a Simpson strong tie p/n DIA 375 or equivalent. Note the minimum holding force required is 500
lb. per fastener and four fasteners are required (two per unistrut minimum).
