About Panels

All panels have guide tabs that align with corresponding slots on the product’s frame. When removing a panel, lift the panel upward to release these tabs from their slots.

Power Off the Station

Power off at the breaker panel and lock out/tag out before continuing work.

Remove the Area Light Bar

1. Using a T25 Security screwdriver, loosen the two captive screws on the area light bar.

   

2. Disconnect the power cable that connects the area light bar to the LED display assembly. Remove the area light bar.

   When reinstalling, ensure the gasket on each end of the area light bar is properly seated around the plastic tab.

   

Remove the LED Display

1. Push the LED display upward to release its guide tabs from their corresponding slots on the Express 250’s frame.

   

2. When the LED display assembly is released, disconnect the five cables from the back.

   When reinstalling, connect the five cables to their corresponding connectors on the back of the display. Leave the area light bar cable (e) loose.

   

   (a) Communications cable (USB Universal Serial Bus-A)

   (b) Holster light cable

   (c) Area light cable x 2 (interchangeable)

   (d) Power cable (24 V)

   Do not allow the LED display to hang from its cables.

Remove the Top Front Panel

1. Using two hands, pull the top panel upward to release its guide tabs from their corresponding slots on the Express 250’s frame.

2. Place a protective cover, such as a lint-free cloth, over the touchscreen to prevent damage during service.

If you are replacing a charging cable, be sure to visit Replace a Holster for information on replacing the holster BEFORE reinstalling the panels.
When reinstalling, push the bottom edge inward to position it inside the groove in the middle vent panel and engage the edge of the sign. Carefully push the panel down until it is firmly seated.
When reinstalling, ensure all five cables at the top of the panel are not captured by the front upper panel, and are easily accessible for reinstalling the LED display.

Remove the Touchscreen

1. Use a T25 Torx driver to remove the M5 screw and washer attaching each touchscreen ground strap to the frame. Keep the screws and washers for reuse.

   

2. Loosen both retention knobs (b), allowing the touchscreen beam (c) to slide up vertically and the touchscreen’s bottom edge to clear the middle vent panel’s slot (d).

3. With hand pressure, tilt the touchscreen upward at a 45-degree angle.

   

4. Allow the touchscreen to return to its lowest position vertically. Rotate the retention knobs clockwise to re-tighten.

   The bottom edge and corners of the touchscreen are sharp. Take care when moving underneath the raised screen.
5. Disconnect all cables from the connectors on the bottom of the touchscreen and remove them from the wire management rings.

   

6. While supporting the touchscreen, continuously rotate the touchscreen’s knobs counterclockwise until they are completely removed. Remove the touchscreen from the station.

Replace the Touchscreen

1. Align the hooks of the new touchscreen’s mounting bracket over the retention knob supports. Tighten the knobs enough to secure the touchscreen.

2. Connect all cables to the underside of the touchscreen:

   1. Proximity sensor cables x 2 (connect left wire to left port, right wire to right port)

   2. Speaker cable

   3. Europe only: meter cable (if applicable)

   4. 24 V DC cable

   5. CAT CPNK ChargePoint Networking Kit Board to DCC Dispenser Charge Controller (Station Management Unit)

   6. LED Display cable (USB Universal Serial Bus-A)

   Perform a pull-push test to ensure that each cable is correctly seated. Failure to connect these correctly could prevent the system from powering on.

3. Connect the proximity sensor wires on the middle vent panel to the corresponding connectors on the bottom of the touchscreen: left wire to left port and right wire to right port.

4. Route any excess wiring through the right-side wire management ring under the touchscreen, to prevent it being pinched in the panels.

5. Route all other cables through the wire management rings on the underside of the touchscreen.

   Ensure all wires are neatly organized and pressed toward the back of the Express 250 to allow the touchscreen to be easily lowered into the slot on the middle vent panel. Ensure the wires are not pinched between the touchscreen and the vent panel.

6. With hand pressure, swing the touchscreen down. Loosen both retention knobs (b), allowing the touchscreen beam (c) to slide up vertically. Re-tighten the knobs at the highest position. Tilt the bottom of the touchscreen inside the slot in the middle vent panel, aligning the notch in the center of the bottom edge (d) to the guide ridge inside the panel slot.



7. Keeping pressure on the edge of the touchscreen to properly seat it inside the panel, loosen the knobs to lower the screen again.

8. With both hands, hold the beam (c) and rotate the top of the bar away from you to relieve stress at the retention knobs. Re- tighten the knobs to secure it.

9. Use a T25 Torx driver to replace the M5 screw and washer (a) attaching each touchscreen ground strap to the frame. Torque to 4 Nm (35 in-lb).

Power On the Station

Once all cover panels are installed, power on the station. The on-screen Installation Wizard steps you through any required tasks to set up the station and verify that it can operate properly.

An Installation Wizard test checks that all cover panels are correctly installed and fully seated. Check the lower right corner of the screen for any error messages. If panel errors appear, match the panel letters to this illustration.

(a) Front bottom panel

(b) Middle vent panel

(c) Front top panel

(d) LED display

(e) Area light bar

(f) Rear bottom panel

(g) Rear middle panel

(h) Rear top panel

(i) Left extrusion

(j) Right extrusion

If any panel needs re-installation, review the procedures above to double-check that all panels are fully seated and that the edges of all signs are captured fully by the panels around them. For further details, refer to Introduction.
