1. Install DC output power cables.
User-supplied; recommended model: AVIC Jonhon CZ36E-4Z-04
•
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

•
The metal terminals must be reliably crimped. Minimum pulling-out force: 300 N for the cross-sectional area
10 AWG or 350 N for the cross-sectional area 6 mm

.
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 Huawei)
•
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.
The user needs to supply a terminal for connecting to the CAN communications cable port. You are advised to use the Weidmüller terminal model BCZ
3.81/02/180 SN GN BX.
NOTICE
3. Set the address DIP switch.
•
The address extension function is disabled: Two address setting switches are used on the address
board to set the address. Up to 36 addresses can be set. Hardware address = (Row address
– 1) x 6 +
Column address
•
The address extension function is enabled: One extension switch and two address setting switches are
used on the address board to set the address. Up to 64 addresses can be set. Hardware address =
Extended address x 36 + (Row address
– 1) x 6 + Column address
•
Switch 7 of S1 indicates the extended address. When switch 7 of S1 is OFF, the extended address is 0.
When switch 7 of S1 is ON, the extended address is 1.
•
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 that the address extension function is enabled, switch 7 of S1 is OFF, switch 1 of S1 is
ON, and switch 3 of S2 is ON. Then, hardware address = 0 x 36 + (1
– 1) x 6 + 3 = 3.
•
The address extension function is disabled by default. To enable the function, send a configuration
command from the monitoring module through the CAN protocol. The configuration can be saved
upon a power failure.
•
Module addresses in the same system cannot be duplicate.
•
The address extension function is disabled: 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.
•
The address extension function is enabled: Ensure that only one switch in S1 or S2 except switch 7
of S1 is ON when setting an address. If multiple switches are ON, an error will occur during
hardware address calculation.
