All ATevos required to share load on the same dc bus must be connected to the same network. The network will consist of a twisted pair cable with ground. The Serial Communication Adapters (A13) on each ATevo must be parallel wired, point-to-point as follows:
| Wiring for Forced Load Sharing | |||||
|---|---|---|---|---|---|
| Cable | Wire | ATevo-A | ATevo-B | ATevo-C | ATevo-D |
| 1 | (-) | TA(-) | RA(-) | ||

| 2 | (-) | TA(-) | RA(-) | ||

Configuring ATevo for Forced Load Sharing
You must assign a charger ID to each ATevo connected in forced load sharing. Configure one as the Primary and all other chargers as Secondary chargers.
To configure an ATevo for Forced Load Sharing:
MENU > COMMUNICATION > Port ‘X’ setup
- ‘X’ is either ‘2’ or ‘3’ for Port 2 or Port 3. The Port configured for forced load share must be the port that the Serial Communications Adapter is plugged into that is wired to the Forced Load Sharing network.
- Select ‘loadshare P’ for the Primary ATevo, or ‘loadshare S’ for Secondary ATevos.
Press the EDIT/ENTER button to accept the new selection. The charger ID may now be changed. Press the ESC button to return to the previous screen. If a port setting was changed, the ATevo will prompt to RESET. Select YES to RESET the ATevo. The new port settings will not become active until after the ATevo is RESET.
To configure ATevo Load Share Charger ID:
MENU > COMMUNICATION > Port ‘X’ setup > Charger ID > select (A, B, C, or D)
- Typically assign Primary charger as ‘A’ and Secondary chargers as ‘B’, ‘C’, and ‘D’
- Example below shows Secondary charger that’s assigned ID ‘B’.
Press the EDIT/ENTER button to accept the new selection. Press the ESC button to return to the previous screen. If a port setting was changes, the ATevo will prompt to RESET. Select YES to RESET the ATevo. The new port settings will not become active until after the ATevo is RESET.
