7.3 Concluding work

1. Finally, check the proper fit of the connectors and the PVC piping.
2. Install the covers of the connection section of the isolator switch and insert the appropriate
fuse inserts in the isolator switch handle.
3. Make sure that the battery inverter or the battery charger is deactivated. Quickly close the
isolator switch handle.
4. Place the cover on the carrier.
5. Fix the cover and carrier with the help of M4x10 flat-head screws supplied along with the battery
system on the left side (see Figure 9).

6. Affix the multi-lingual danger sticker on the left side of the battery carrier.
7. Affix the safety signs "Danger - Batteries" and "Smoking prohibited" outside on the door of
the battery room.

8 Operating the battery system

8.1 Impact of temperature

The recommended operating temperature range for lead-acid batteries is between 10 °C and 30 °C.
The technical specification applies for the nominal temperature of 20 °C. The ideal operating
temperature range is 20 °C ± 5 K. Higher temperatures decrease the service life (a temperature
increase of 10 °C halves the calendar service life). Lower temperatures reduce the available capa-
city. The limit temperature of 55°C must not be exceeded. Continuous operating temperatures of
45 °C or more must be avoided.

8.2 Configuration of the battery inverter

Follow the current specifications of the inverter manufacturer and the following parameter values
specified by HOPPECKE for the general configuration.
