NEMA Plug-in Outlet

This section introduces how to install a NEMA outlet if you do not have one already.

WARNING Switch off the circuit breaker of the electrical outlet before installing your charger.
IMPORTANT When installing a NEMA 14-50 outlet, ensure that the ground pin is facing up as shown per the diagram.

• Ensure you have the correct permits for this electrical installation.
• The power supply cable length is limited to 11.8” (30 cm).

CAUTION To reduce the risk of fire, connect only to a circuit with a branch circuit over-current protection of 50 A by ANSI/ NFPA 70 (US) C22.2 NO.280-13 (Canada).

Installation

To find the ideal mounting height of the charger.

DANGER Risk of shock. Turn off the power to the outlet at the circuit breaker until the installation is completed.

• Find the wall stud nearest to the NEMA outlet and draw a vertical line.
• Plug the NEMA cable into the outlet, and position the charger centered on the vertical line. Ensure that the NEMA cable has a slight curve and is not stretched.
• Mark a horizontal line at the bottom of the charger.
• Unplug the charger.

Charging Station Installation

1. Place the bracket with the bottom edge aligned with the horizontal line. Mark the 4 mounting holes (M4) and remove the wall dock.
2. Drill 4 holes and insert wall anchors into the mounting holes. Attach the bracket to the mounting location by screwing 4 Type B Screws (M4 x 30 mm) into the mounting holes then tighten them.
3. Attach the charger to the bracket by inserting the mounting screws (D) on the back of the charger into the bracket mounting holes (C). Slide the charger downwards.
4. Screw the Type A Screw (M4 x 12 mm) into the hole at the side of the charger and tighten the screw to secure the charger.

Cord Holder Installation

1. Place the cord holder on the wall and keep it level, and mark the 3 mounting holes (M4), then remove the holder.
2. Drill 3 holes and insert 3 wall anchors into the mounting holes. Place the holder, then screw and tighten 3 Type B Screws (M4 x 30mm) into the mounting holes.

Charging Operation

Plug-and-Charge Mode (Default)

• When the charging station is on standby, plug in the connector to your EV, and the LED will turn blue from purple.
• The LED will be flashing green while charging.
• When your EV is fully charged, the LED will be solid green, unplug the connector and place it back into the holder.

If you need an emergency stop while charging, please press the RESET BUTTON then unplug the connector.

RFID Mode

1. How to the Enable the RFID Cards
   • A) When the charging station is on standby, press the RESET button and hold till the LED turns orange from purple.
   • B) Place the RFID card into the RFID Reader (Interrogator) within 15 seconds and wait till the LED turns back to purple.

NOTE

1. Another RFID card will automatically be enabled without any operation.
2. Once you enable the RFID mode, the plug-and-charge mode will be disabled, if you want to use the plug-and-charge mode, please contact us for tech support.

RFID Charging Mode

• When the charging station is on standby, plug in the connector to your EV, and the LED will turn blue from purple.
• Tap the RFID card on the RFID Reader.
• The LED will be flashing green while charging.
• Tap the RFID card on the RFID Reader again to stop charging.
• When your EV is fully charged, the LED will be solid green, unplug the connector and place it back into the holster.

Troubleshooting

switches in the power distribution box.

2.   Check whether the input cables are grounded correctly.

3.   After the fault is rectified, power on the device again. If the fault persists, contact us.

The red light flashes slowly twice and quickly twice, alternately cycle.| Output Overcur- rent| 1.  Immediately turn off the leakage/over- current protection switches in the power distribution box.

2.   Check whether there is low imped- ance or short circuit between the char- ger output line.

3.   Ensure the charging current to less than 35A.

4.   After the fault is rectified, power on the device again. If the fault persists, contact us.

The red light flashes slowly twice and quickly for 4 times, alternately cycle.| Over-heating| 1.  Check the charger installation envi- ronment.

2.   Check whether there are other heat- ing devices nearby.

3.   Ensure that the ambient temperature is below 50℃ .

The red light flashes slowly for 3 times and quickly for 2 times, alternately cycle.| Input Overvoltage| If the voltage exceeds 265Vac for a short time,wait for the power gird to re- store itself to the normal voltage range. Contact local power grid company if the voltage fault persists.
