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 in accordance with 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.

5.1 Charging Station Installation
5.1.1 Place the bracket with the bottom edge aligned with the horizontal line. Mark the 4 mounting holes (M4) and remove the bracket.

5.1.2 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.

5.1.3 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.

5.1.4 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.

5.2 Cable Holder Installation
5.2.1 Place the holder on the wall and keep it level, and mark the 3 mounting holes (M4), then remove the holder.

5.2.2 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.

4. Please note that the EV charger can still function even if its cables are not grounded. However, it is highly recom- mended to ensure that all cables are properly grounded.
The red light flashes slowly twice and quickly twice, alter- nately cycling.| 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 once, alter- nately cycling.| Relay Adhesion| Please contact us if the fault persists.
