ACTURA Flex 48330 Power System User Manual
6.4 Cover Plates
The Multi-Function Unit has a cover plate to protect the load and battery circuit
breakers and to create a neat finish. This cover plate is easy to open/remove in
order to switch on or off a circuit breaker, or to connect additional loads. The
cover plate can be opened or removed without the need of using special tools. The
DC section of the Distribution Unit is made safe for a “User” to access, which
follows the “Look and Feel” guidelines.
6.5 Battery Maintenance
6.5.1 Storage And Supplementary
During storage, the capacity of the battery decreases because of self-discharging.
When using a stored battery, always carry out supplementary charging before use.
Refer to the battery user manual or follow battery manufacturer’s advices to
perform supplementary charging.
Store the battery in a cool dry place.
6.5.2 Daily Inspection
1. Check the battery regularly. The battery needs to be replaced if any abnormal
condition occurs, such as:
Any voltage abnormalities;
Any physical defects (e.g., a cracked or deformed container cover);
Any electrolyte leakage;
Any abnormal heat generation.
2. Clean any dust contamination with a wet cloth. Never use organic solvents
(gasoline or thinners), otherwise the container or cover may crack.
3. Voltage checks.
Total voltage
The total voltage of the batteries should not deviate from the recommended 2.25 V
per cell (54V in a 48V DC power system at reference temperature). If it deviates,
check your system to see that the setting is correct and that the temperature
compensation is correct.
