If installing block batteries with L-connectors you should consider, that L- connectors have to be
mounted before positioning the battery block in the battery cabinet.
Note:
The L-connectors are not intended for high current applications (e.g. UPS). Please contact
your local HOPPECKE representative in case of questions.
5.7 Handling the batteries
Be very careful when lifting and moving the batteries as a falling battery could cause personal injury or material
damage. Always wear protective shoes and safety goggles.
Install the battery in accordance with VDE 0510 Part 2: 2001-12 (in accordance with IEC 62485-2).
For example, you must cover conductive parts using insulating mats.
Make sure that all terminals are covered with insulating caps.
5.8 General information on connecting the batteries
Attention!
If connecting the batteries, always establish the serial connections first followed by the parallel
connection. Do not reverse this procedure.
Before connecting, check to make sure that the batteries have the correct polarity.
To establish the serial connection, arrange the batteries so that the positive terminal of one bat-
tery is positioned as near as possible to the negative terminal of the next battery.
If sealed stationary batteries are connected in parallel, observe the following:
1. Only battery strings with the same length and voltage may be connected with one another. Cross connecting
the individual strings between the cells should be avoided because strings could be very long. Cross connec-
tions mask bad cells and blocks and could cause individual battery strings to overload.
2. Only batteries of the same type and same state of charge should be connected (same battery type, plate
size and plate design).
3. The environmental conditions should be the same for each string connected in parallel. In particular, avoid
temperature discrepancies between the individual strings/batteries.
4. In order to ensure consistent current distribution, make sure that the connectors and end connections are set
up so that the individual supply lines connected to the consumer have the same electrical resistance ratio.
5. The commissioning date of the batteries should be the same (batteries of the same age, identical storage
time and same state of charge).
If the installation does not comply with all of the above mentioned guidelines, you have to charge each string
separately and connect them in parallel afterwards.
1. If the installation drawing is available, mark the outlines of the racks on the installation surface using chalk.
2. The installation surface must be level and rigid. If backing elements are used, make sure that the thickness
does not exceed 6 mm.
3. Carefully set up the racks and arrange them horizontally.
4. The distances of the support profiles must correspond to the dimensions of the cell or monobloc battery.
5. Check rack stability and ensure that all screwed and clamp connectors are firmly secured.
6. If necessary, ground the racks or rack parts.
If using wooden racks: you must fit a flexible connector between each rack joint.
Attention!
5.6 Cabinet installation
Alternatively, you may choose to install the batteries in HOPPECKE cabinets.
The cabinets can be delivered with batteries already installed or battery installation can take
place on-site.
HOPPECKE provides different types of cabinets.
Danger!
The installation location must fulfill the conditions described in
Chap. 5.1
.
Comply with the minimum distances listed in
Tab. 5–1
.
