5.5 Rack installation
We recommend that batteries are properly installed in HOPPECKE battery racks or HOPPECKE
battery cabinets. The use of other operator-specific solutions may render the warranty for the
batteries null and void.
HOPPECKE produces different types of racks. For installation information, see the separate docu-
mentation included with each rack.
Danger!
Observe the special requirements and regulations when installing battery racks in seismic areas!
Danger!
The installation location must fulfill the conditions described in
Chap. 5.1
.
Comply with the minimum distances listed in
Tab. 5–1
.

Another sample calculation for battery room ventilation is available in Required ventilation for
hydrogen generated by batteries,
Chap. 10, „Required ventilation for hydrogen generated by bat-
teries“.
5.3 Conducting an open-circuit-voltage measurement
Before installing the batteries, conduct an open-circuit voltage measurement of the individual
cells or monobloc batteries to determine their state of charge and to make sure that they are
functioning properly. Fully-charged cells with an electrolyte temperature of 20 °C should have an
open-circuit voltage as listed in
Tab. 5–3
.
The open-circuit voltages of the individual cells of a battery must not differ more than 0.02 V
from one another.

Tab. 5–3: Open circuit voltages for different cells/block batteries
The following open-circuit voltage deviations are acceptable for monobloc batteries:
– 4 V monobloc 0.03 V/block
– 6 V monobloc 0.04 V/block
– 12 V monobloc batteries 0.05 V/block
High temperatures decrease the open-circuit voltage while lower temperatures increase it. A
deviation of 15 K from the nominal temperature changes the open-circuit voltage by 0.01 V/cell.
Please consult your local HOPPECKE representative regarding larger deviations.
5.4 Installation tools and equipment
The batteries are delivered on pallets and the required accessories are located in separate packaging units.
Observe all information from the previous sections.
Danger!
For the installation, you will require your personal safety equipment, protective clothing, safety
tools and other equipment as described in
Chap. 2.2
.
