1.The information in this document is subject to change due to version upgrades or other reasons. Every effort has been made in the
preparation of this document to ensure accuracy of the contents, but all statements, information, and recommendations in this document do
not constitute a warranty of any kind, express or implied.
2.Before installing the device, carefully read the user manual to get familiar with product information and safety precautions. You can log in to
http://support.huawei.com/enterprise/ and search for the device model on the Product Support tab page to view or obtain the user manual.
3.Only qualified and trained electrical technicians are allowed to operate the device. Operation personnel must wear proper personal protective
equipment (PPE) all the time.
4.The charger module does not have the battery reverse-connection prevention function. The charging machine (pile) needs to detect battery
reverse-connection prevention. The module failure caused by battery reverse-connection is not covered under the warranty.
5.When operating Huawei equipment, follow the precautions and special safety instructions provided by Huawei. Huawei will not be liable for
any consequences that are caused by the violation of safety regulations and design, production, and usage standards.
6.Do not remove the warranty label or barcode from the charger. Otherwise, product warranty will be forfeited.

2Installing the Charger
Checking Before Installation
2.1
Before unpacking the charger, check the outer packing materials for damage, such as holes and cracks, and check the charger model. If any
damage is found or the charger model is not what you require, do not unpack the charger but contact the supplier as soon as possible.
Mounting Hole Sizes (unit: mm)
Checking Outer Packing Materials
Checking Deliverables
After unpacking the charger, check whether the deliverables are
intact and complete. If any damage is found or any component is
missing, contact your supplier.

Tools
Installing the Charger
2.2
The charger can be installed horizontally, sidewards, or vertically (with the panel at the bottom). If side or vertical installation is adopted,
ensure that mechanical parts are designed to avoid interference. The installation mode can be selected according to the actual situation.
Horizontal installation is recommended and vertical installation is not recommended.
Horizontal Installation (Recommended)
1. (Optional) Determine whether to
install the mounting ear based on the
site requirement.
2. Slowly push the charger into the slot.
3. Tighten the charger.
4. After the installation is complete,
seal the cable holes of the cabinet.
Side Installation
Vertical Installation
(Not Recommended)
Vertical installation is
not recommended
because doing so
will cause
maintenance
difficulty as you will
be unable to locally
check whether the
charger is running
(the indicators are
invisible because the
panel faces
downwards).

3. Install CAN communications cables.
1. Install DC output power cables.
•The metal terminals are delivered together with the DC output terminal.
•The recommended crimping tool is XCXY-02. The locator model is DWQ-18.
•Recommended heat-shrink tubing diameter: 6 mm; recommended temperature resistance: 125°C; recommended baking temperature:
110°C
•The metal terminals must be reliably crimped. Minimum pulling-out force: 300 N for the cross-sectional area 5.26 mm2or 350 N for the
cross-sectional area 6 mm2.
NOTE
The DC output terminal can be installed in the following two scenarios. Install it based on the site requirement.
•Used with an address board (DC output terminal and address board supplied by the user)
•Not used with an address board (DC output terminal supplied by the user)
A 120-ohm resistor must be connected in parallel between the cables of the first and last chargers. Otherwise, communication may be poor.
Keep a distance of 3–5 mm between the front end of the heat shrink tubing and the metal terminal buckle.

Power-On Check
3.5
After installation and power-on, the green indicator on the charger blinks slowly
(the charger is in sleep state by default after being powered on). After the
monitoring module delivers a startup command, use a multimeter to check
whether the voltage at the cabinet copper bar connected to the output terminal
of the charger is within the normal range (200–950 V DC). Check that the
green indicator on the charger is steady on, indicating that the charger is
running properly.

4. Set the address DIP switch.
•Hardware address = 6 x (ON switch No. of S1 –1) + ON switch No. of
S2
•Switches 1–6 of S1 correspond to row addresses 1–6. Switches 1–6 of
S2 correspond to column addresses 1–6.Switch 8 of S1 and switches 7
and 8 of S2 are invalid so they do not need to be operated.
Example: Assume the first switch of S1 is ON and the third switch of S2
is ON. Then, hardware address = 6 x (1 –1) + 3 = 3.
•The mapping between DIP switch settings and addresses see the user
manual.
•Module addresses in the same system cannot be duplicate.
•Ensure that only one switch in S1 or S2 is ON when setting an
address. If multiple switches are ON, an error will occur during
hardware address calculation.
Example (Hardware Address: 3)
Keep a distance of 3–5 mm between the front end of the heat shrink tubing and the metal terminal buckle.
