Power-On Commissioning

12.1 Measuring Voltages
Mains Scenario (Lead-Acid Battery)
1. Use a multimeter to measure the voltages at both battery
terminals and ensure that the values are in the range of 43.2 V
DC to 56.4 V DC.
2. Use a multimeter to check that the voltage of the AC input circuit
breaker is in the range of 85 V AC to 300 V AC.
3. Switch on the battery circuit breaker and AC input circuit breaker.
Solar Scenario (Lead-Acid Battery)
1. Use a multimeter to measure the voltages at both battery
terminals and ensure that the values are in the range of 43.2 V
DC to 56.4 V DC.
2. Switch the battery circuit breakers to ON.
3. Insert the PV input connector into the SSU to connect the solar
power supply.
Mains Scenario (Lithium Battery)
1. Use a multimeter to check that the voltage of the AC input circuit
breaker is in the range of 85 V AC to 300 V AC.
2. Switch on the battery circuit breaker and AC input circuit breaker.
3. If the lithium battery model is ESU-A2400Wh/D, flip the ESMU
power switches to ON.
12.2 Setting the Display Language
After powering on the SMU, select the display language by pressing
enter the system information screen.
To change the language that you have set, remove and then reinsert the SMU. Restart the SMU, and select a language again.
12.3 Setting Parameters
NOTE
The LCD screen becomes dark if no button is pressed for 30 seconds.

You need to log in again if no button is pressed for 1 minute.

 The preset password is 000001.
The other end of the activation cables are connected before
delivery.
Switch off the battery circuit breaker, load

circuit breaker, AC input circuit breaker,
and M48300N1 circuit breaker.
Verify the battery cable connections.

Solar+Mains Scenario (Lead-Acid Battery)
1. Use a multimeter to measure the voltages at both battery
terminals and ensure that the values are in the range of 43.2 V
DC to 56.4 V DC.
2. Use a multimeter to check that the voltage of the AC input circuit
breaker is in the range of 85 V AC to 300 V AC.
3. Switch on the battery circuit breaker and AC input circuit breaker.
4. Insert the PV input cable connector into the SSU to connect the
solar power supply.
For the preparation of the PV input cable connector, see the
appendix.
Solar+Mains Scenario (Lithium Battery)
1. Use a multimeter to check that the voltage of the AC input circuit
breaker is in the range of 85 V AC to 300 V AC.
2. Switch on the battery circuit breaker and AC input circuit breaker.
3. If the lithium battery model is ESU-A2400Wh/D, flip the ESMU
power switches to ON and wait for the initial power-on.
4. Insert the PV input connector into the SSU to connect the solar
power supply.
When there is no AC input in a solar+mains scenario (lithium
battery), remove the PSU, connect the battery supply, and then
reinstall the PSU.
