Check Manual Equalize (if configured). Click the Start Manual Equalize button on the
Charge page to initiate a battery equalization. Click the Stop button at the top of the
Charge page to end.
A Battery MCB Fail alarm is generated from the voltage measured across the battery MCB.
Therefore, to check a Battery MCB Fail alarm, simply open one of the battery MCB's. If batteries
are connected to the system at this time, the alarm may take a few moments to activate. Once
test is complete, turn breaker back on.
Battery MCB Fail (urgent)
Temperature Compensation
Check Temperature Compensation is enabled.
Web UI Battery>Battery Settings>Rectifier Compensation>On.
Apply heat or cold to the Battery Temperature Sensor/s. Check the float voltage
moves up or down as expected.
If actual measurement is required, apply a known heat or cold to the sensor. Allow it
to fully come to temperature and record the amount of voltage movement.
Check Alarm Relay Contacts
To generate these alarms, refer to the procedures described earlier in the Commissioning
Checklist.
Spare relays will not be able to be tested unless an alarm is mapped to them. As these are tested
in the factory, it is not essential to test them at time of commissioning.
Relay 1 (Monitor Fail) (pull out the RJ45 lead connecting the monitor to the system
rectifier shelf – this simply de-powers the monitor)
Relay 2 (Summary Non-urgent)
Relay 3 (Summary Urgent)
Relay 4 (Spare)
Relay 5 (Spare)
Relay 6 (Spare)
NOTE: Prior to leaving the system after it has been commissioned, check all AC, DC and battery circuits
are off. If it is required that the system is to be left on (to power load equipment, ensure
rectifiers are left in their powered-up state, and batteries are in circuit. This will prevent anyone
leaving the batteries only powering the load (in which case the batteries go flat).

Systems with Lithium Batteries
The term lithium batteries include a wide range of chemistry types. Regardless of the chemistry used
the energy manager differentiates lithium (and other non-lead acid batteries) by whether the battery
BMS can be communicated to via Modbus RTU or not. These 'smart' batteries are termed modular,
where the energy manager is receiving information on alarms and status from the battery internal
electronics.
Failure to correctly follow the items below may cause incorrect system functionality and, in some
cases, ruin your battery (without the ability to claim battery replacement under warranty).
NOTE: Any values shown below are indicative only. If the values in your system differ from those
shown here, write in the values relevant to your system. Refer to the EM4x energy manager
manual for more details.
