Setting up the PF-JT48

Step 1: Planning

What’s in the box

PF-JT48 chargers are shipped with the following components. Carefully remove from the shipping box.

PF-JT48 Charger (with the

connection and charging

cables)

Mounting bracket and 2x M5

teeth screws (to be mounted on

back of charger)

4x M6 hexagonal expansion

anchor screws

What you’ll need

You can install the PF-JT48 charger to a wall or pedestal. Check your site plan and before installing the

wall-mounted charger, gather the following tools and equipment:

▪Phillips screwdriver

▪Drill and drill-bit (¼") for expansion anchor screws for wall installation

▪Drill and 1 1/8" (29 mm) drill-bit for pedestal installation

▪Drill and 3/8" drill bit for cable retractor

▪Voltmeter or digital multimeter for measuring AC voltage at the installation site

▪AWG #6 wire nuts for connecting wiring in the junction box

▪Level (any 9-inch torpedo level will do) to make sure that brackets are installed correctly

▪Pencil (or magic marker) to mark where drilling should occur

▪Wrench (or wrench socket) that can work with 3/8" bolt (for cable retractor)

Step 2: Installation

To install the PF-JT48, you’ll do the following:

▪Mount the EV charger to a concrete wall

▪Mount the EV charger to a pedestal

▪Install cable management

Before continuing with any installation, practice this safety measure:

Make sure that electrical breakers are switched off so that no electricity is flowing during installation.

Mounting the PF-JT48 on a wall

This picture shows how the EV charger would look like once installed on the wall (with a junction box):

1. Identify where the charger is to be installed on the wall.

Installation notes:

▪PowerFlex recommends that the base of the station should be between 48" and 58" (1.219 m

to 1.473 m) from the ground.

▪For ADA compliance, the station’s QR code should be no higher than 48" (1.2 m), which means

that the bottom of the station should be no higher than 45" (1.14 m) from the ground.

▪Make sure that the location of the charger is compatible with the location (or expected

location) of a mounted junction box where the wires from the electrical panel will terminate.

2. Remove the mounting bracket from the back of the charger by removing the two screws on the side

of the charger.

3. Place the mounting bracket on the wall at a location no higher than 45" from the ground.

4. Use a level to ensure the plate is level (L) and mark the positions for the four screws on the wall (R):

5. Place the mounting bracket to the side and pre-drill four ¼"holes into the wall:

6. Using the provided anchors and screws, attach the mounting bracket onto the wall:

7. Remove the two screws on the side of the charger. Carefully slide the charger onto the mounting

bracket (L) and lock it into place with the screws (R). Verify that the charger is securely fastened on

the wall.

8. Connect the chargers’ wires to the circuit branch wires in a junction box, using AWG #6 wire nuts:

Use cable gland waterproof connectors,

if necessary.

You can use a single junction box with

two PF-JT48 chargers.

For safety reasons, make sure that the front opening of the junction box is covered.

The PF-JT48 is now mounted on the wall. To complete the installation, you’ll need to spend a few more

minutes doing cable management.

Mounting the PF-JT48 on a pedestal

Note: The initial mounting instructions for the PF-JT48 charger on a pedestal is similar to mounting

the charger onto a wall.

1. Identify where the charger is to be installed on a pedestal.

Installation notes:

▪PowerFlex recommends that the base of the station should be between 48" and 58" (1.219 m

to 1.473 m) from the ground.

▪For ADA compliance, the station’s QR code should be no higher than 48" (1.2 m), which means

that the bottom of the station should be no higher than 45" (1.14 m) from the ground.

▪Make sure that the location of the charger is compatible with the location (or expected

location) of a mounted junction box where the wires from the electrical panel will terminate.

2. Remove the mounting bracket from the back of the charger by removing the two screws on the side

of the charger.

3. Place the mounting bracket on the pedestal at a location no higher than 45" from the ground.

4. Use a level to ensure the plate is level and mark the positions for the four screws on the pedestal.

5. Place the mounting bracket to the side and pre-drill four ¼"holes into the pedestal.

6. Attach the mounting bracket onto the pedestal using M6 screws (not provided).

7. If no wire management hole exists in the pedestal, use a 1 1/8" (29 mm) drill-bit to drill a hole

between 6-12 inches under the location of the charger, directly under the left cable. Use a 1" cable

gland to waterproof the cable opening:

8. Pass the charger wiring cable through the hole and connect to the circuit branch opening in the

pedestal. Connect the cables with wire nuts inside the pedestal to the junction box:

For safety reasons, make sure that the wiring opening is covered. To complete the installation, you’ll

spend a few more minutes to perform cable management (in the next section).

Finishing up with cable management

Cable management is important to complete for every EV charger installation. This includes the

installation of the following:

▪A charging connector holster

▪A cable retractor or a high-point anchor

Install a charging connector holster

At the end of a charging cable is a charging connector that is inserted into a vehicle for charging. For

safety reasons, the charging connector should be hung up when not in use. Two holsters are offered:

Direct holster

Z holster

Both holsters come with two sets of screws to be used depending on where it will be installed. For

pedestal installation, install the holster underneath the station using the four screws. For wall

installation, install the holster on a nearby wall using the four anchor screws.

Install a cable retractor or a high-point anchor

Another key cable management feature improves safety by keeping the charging cable off the ground,

avoiding the risk of tripping, and reduces cable wear.

PowerFlex offers a cable retractor provides spring-loaded tethered support and suspends a charging

cable above the mounted charger when not in use. A cable retractor releases the charging cable when a

vehicle is being charged.

A cable retractor can be installed for either wall or pedestal installations with two simple steps:

1. Mount the retractor to the wall or pedestal

2. Mount the charging cable to the cable retractor

The cable retractor provided by PowerFlex has the following components:

Item

Description

Mounting holes on the cable retractor

Cable retractor rope (on the cable retractor)

Cable clamp (on the cable retractor)

4x 3/8" wall anchor bolt for mounting on the wall (with washer and nut)

4x 3/8" short bolts for mounting on a pedestal (with washer and nut)

To mount the retractor to the wall or pedestal:

1. Identify the best location for the cable retractor. We recommend 2-3 FT above the mounted

charger.

2. Place the retractor on the surface, use a level to make sure it is straight, and mark the four screw

locations on the wall or pedestal.

3. Place the retractor to the side. Using a 3/8" drill bit, drill holes at the four marked screw locations.

4. Remove the nut and washer from the wall-mounting nuts and bolts.

5. Insert each bolt with a wall anchor in the drilled holes.

6. Place the retractor and the washers on the bolts and secure by tightening the nuts with a wrench

socket.

Note: If mounting on a pedestal, use the four short bolts to secure the cable retractor.

To mount the cable to the retractor:

1. Pull the cable retractor rope so that the cable

clamp touches the floor and ls firmly in

position. The cable clamp is shown below:

2. Unscrew the two screws on the retractor’s

cable clamp:

3. Insert the charging cable in the cable clamp

(both front and back view shown):

4. Put the cable clamp pieces back together and

then reinsert the nuts and bolts (back view

shown):

Installation notes:

▪Place the cable clamp along the charging cable, at least 2 feet to the top of the charger. Also,

Give the cable slack to the bottom of the charger as shown in the picture:

Ensure the cable is not twisted between the

charger and the cable clamp.

The high-point anchor is an alternative to the cable retractor that is not provided by PowerFlex. This

simple assembly can be mounted on a wall or onto a pedestal.

1. Using a ¾" metal cable clamp with

rubberized cushions, route the charging cable

2-3 FT above the charger. Make sure there

are no twists in the cable.

2. Install a cable clamp to hold the cable.

3. Use a ¼" diameter screw with a wall anchor

as appropriate for the wall material to secure

the cable clamp to the wall.

Before proceeding to the next step …

1. Confirm that the PF-JT48 charger is securely mounted to a wall or pedestal.

2. Perform a quick verification that all cables to the charger enclosure are fully connected.

Step 3: Inspection

Inspection is performed once the entire PowerFlex system is ready to be energized, commissioned, and

validated. Inspection is where installation information is recorded and a request for commissioning with

PowerFlex is initiated.

PowerFlex uses a customized mobile app, available from either the Google Play store or the Apple

Store, called FastField Forms (FFF). This app enables installers to gather important installation

information and photographs for each PF-JT48 charger being installed:

More about using the FFF app …

▪Nexus Core Installation Guide —includes download and instructions for how to use the FastField

Forms (FFF) app and how to energize and commission the PowerFlex system.

Step 4: Validation

Once the PF-JT48 charger information is entered and the rest of the PowerFlex stations are recorded in

the app, the installer submits the forms to PowerFlex for review and commissioning. After the go-ahead

from PowerFlex, the final validation step is performed.

To perform an end-to-end validation, you’ll energize with power and confirm each PF-JT48 works as

expected. There are three LED light indicators on the front of the charger that indicate its status:
