DC charging equipment user manual

Copyright Notice Thank you for using Growatt THOR EV
chargings equipment
THOR series intelligent DC charging equipment is a device that provides high-
efficiency, safe and stable DC power supply for electric vehicles, which has a
friendly man-machine interface and integrates corresponding functions of control,
billing, communication and security protection. The mode charging equipment
uses OCPP 1.6JSON open protocol for communication with back-office server,
thus to realize functions such as reservation and network payment via mobile APP.
Diversified communication options, including wired Ethernet, WIFI, 4G wireless,
are provided for customers to conveniently connect the device to a charging
network.
We sincerely hope that this product can meet your needs, and we welcome
andvalue your feedback and suggestions on the performance and function of the
product. We will continuously improve the quality of our products and services.

III. Installation and wiring
1. Firstly, according to the specific installation height requirement of the user,
determine the installation height of the charging equipment and the installation
height of the cable holder. According to the dimensions in the following drawings,
drill 4 holes for bracket mounting and 3 holes for cable holder mounting on the
wall. Take out the expansion bolts in thepacking accessory bag, hammer the
expansion bolts into the holes. Remove the nuts and washers for later use.
2. Loosen the 2 screws at the bottom of the charging equipment that fixes the
mounting bracket, keep them properly for later use. Place the mounting bracket
onto the bolts just installed and screw the nuts and washers. Take out the cable
holder and fix it using the same procedure.
3. After the mounting bracket and cable holder are fixed, place the charging
equipment onto the mounting bracket, with the outward bent part inserted to the
slot on the rear side of the charging equipment. Lock the charging equipment onto
the bracket at the bottom using the 2 screws. The installation is done.

4. Now prepare for wiring. Use 4 power cables and 1 PE cable, it is suggested to
use a 5-core cable(with PE included) for the convenience of using the water-proof
cable gland. The live wires shall be at least 6mm², PE shall be greater than 6mm².
Open the 2 locks at the right,Connect the AC input cables into the corresponding
terminals through the cable gland on the bottom right side and fasten them(Refer
to the Internal view and terminal definition part for wire connection), Connect the
network cable through the hole in front of the AC input cable gland to the RJ45
socket and fasten the water-proof gland. Close and lock the upper cover after
checking internal wiring and breaker position. The wiring is then finished.
Notice
1. Only professional person can do the wiring. Please connect the AC input wires
according to the correct phase order which is marked on the terminal block.
2. The PE terminal shall be connected to the Earth firmly and reliably!
3. Turn off the upstream breaker in the distribution panel before repairing or
maintaining.
4. Please do no disassemble the unit unless authorized!
