•This document describes how to use the output terminal, address board, and input
terminal that are applicable to 15 kW and 20 kW chargers.
•The address board needs to be soldered to the output terminal and connected to the
output terminal of the charger.
•The input terminal is connected to the input terminal of the charger, as shown in the
following figure.
•The terminals and address board described in
this document apply to 15 kW and 20 kW
chargers.
•The terminals and address board described in
this document need to be supplied by the user,
not Huawei.

•DC output +, DC output –, hardware address line,
charger in-position detection, and control ground signals
are hazardous voltages so basic insulation is designed
between these signals and the enclosure.
•The CAN signal line is a safety extra-low voltage (SELV).
Functional insulation is designed between this signal
and the enclosure; enhanced insulation is designed
between this signal and hazardous voltages.

The charger provides the hardware address function. It interacts with an address board and different pull-down resistors to set different
addresses. The address board supports up to 36 addresses.
The resistor selection method is the same for ADDRESS_0 (row No.) and ADDRESS_1 (column No.). Install pull-down resistors R0 and R1
according to the following figure and table.

Preparing Cables
4.1
Determine the heat resistance grade of the cable insulation material based on the ambient temperature. It is recommended that the cables
resist heat of at least 105°C.

•
If a single cable is used as the output power cable, the
specifications depend on the result of temperature rise test
for cables inside the cabinet. If the maximum cable surface
temperature is lower than 90°C, the specifications meet the
requirements. Otherwise, use two cables.
•
If the AF200 high temperature-resisting cable with the same
cross-sectional area is configured (allowed long-term
temperature: 200°C), a single cable meets the requirements.

•The metal terminals are delivered together with the DC output terminal and AC input terminal.
•The recommended crimping tool is XCXY-02. The locator model is DWQ-18.
•Recommended heat-shrink tubing diameter for output power cables of the 15 kW charger: 6 mm; recommended temperature resistance:
125°C; recommended baking temperature: 110°C. Recommended heat-shrink tubing diameter for input power cables: 4 mm; recommended
temperature resistance: 125°C; recommended baking temperature: 110°C
•Recommended heat-shrink tubing diameter for the 20 kW charger: 6 mm; recommended temperature resistance: 125°C; recommended
baking temperature: 110°C
•The metal terminals must be reliably crimped. Minimum pulling-out force: 250 N for the cross-sectional area 12 AWG or 280 N for the cross-
sectional area 4 mm2; 300 N for the cross-sectional area 10 AWG or 350 N for the cross-sectional area 6 mm2.
NOTE
•A 120-ohm resistor must be connected in parallel between the cables of the first and last chargers. Otherwise, communication may be poor.
•It is recommended that twisted pairs be used as CAN communications cables.

2.Set the address DIP switch.
Hardware address = 6 x (ON switch No. of S1 –1) + ON switch No. of S2
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.
Example (Hardware Address: 3)

•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.
•If all switches of S1 or S2 are OFF, the address is invalid.
•Switches 7 and 8 of S1 and S2 are invalid so they do not need to be operated.
