Installation

Step 2: Check the battery(ies)

↻ Battery(ies) fitted.
1. Insert the DC breaker(s) into the DC breaker socket on the battery(ies).

2. Check the idle voltage using suitable measuring equipment.
3. Measure for any possible deviation of the idle voltage between the batter-

ies.

In the event of a deviation below or at 0.5 V, carry out the next step and

proceed with Step 3.

4. Remove DC breaker(s).

Figure 2: Connection of a suitable DC source ensuring the correct polarity

In the event of a deviation over 0.5 V, other steps are necessary:
1. Connect a suitable DC source to the relevant battery module.

(Observe the correct polarity!) (See figure 2)

2. The specified voltage of the DC source must correspond to the maximum

voltage of one of the battery modules installed.

(Maximum permissible charging voltage: 52 V)

3. Restrict the specified current of the DC source to 5 A.
4. Start the charging process.
5. Switch off the DC source when the charge current is at 1 A to 2 A.
6. Repeat steps 2 - 4 for all batteries until the relevant idle voltage deviation

of the individual modules reaches 0.5 V in relation to one another.

7. Remove DC breakers after the idle voltages have been equalised.

Connect battery(ies) to the Battery Management System (BMS).
