4 Preparations for battery installation
As can be seen from the calculation, no complex technical
ventilation (e.g. explosion-proof fan) is required even when
using the largest battery.
Furthermore, due to the low-maintenance, leak-proof lead
batteries used, no special constructional requirements such
as electrolyte-resistant floor or floor covering (tiles, door sill)
etc. have to be met.
Sealed lead-acid batteries can always be operated in any
position (except head position).
Determination of the aeration and ventilation of electrical
operating rooms in accordance with DIN EN IEC 62485-2

4 Preparations for battery installation
Check all blocks by measuring the open-circuit voltage.
6 Volt block: U 6.33 V
12 volt block: U 12.66 V
• When measuring the open-circuit voltage, the correct
polarity (possible incorrect installation) must be observed
at the same time.
• If drawings were supplied by CEAG Notlichtsysteme
GmbH, these must be observed during installation.
• The frames must be horizontally aligned and load-bearing.
For rack mounting from 4 levels and 2 rows or 5 levels
and 3 rows, the rack should also be firmly anchored in the
battery room.
• Racks and cabinets should provide adequate ventilation
above and below to allow sufficient dissipation of the
heat generated by batteries and their charging system.
The distance between cells or blocks should be 10 mm,
but at least 5 mm.
4.1 Mounting Battery Blocks and Battery
Block Sensors
Insulated tools must be used for the assembly work. Wear
rubber gloves, goggles and protective clothing (incl. safety
shoes). Remove metal objects such as watches or jewellery.
Mount the supplied battery block sensors type BBS, pole
covers for insulation of the battery poles with the battery
connectors. Tighten the battery connector with an insula-
ted torque wrench. The following torques apply to screw
connections:
• G-M5 flat terminal: 5 ± 1 Nm
• M6 threaded bolt: 6 ± 1 Nm
• M6 threaded hole: 11 ± 1 Nm
• M8 threaded bolt: 8 ± 1 Nm

• M8 threaded hole: 20 ± 1 Nm
• M12 threaded bolt: 25 ± 1 Nm
• Inch 10-32x0.425: 6 ± 1 Nm
After completion of the installation work, thinly coat the
connection surfaces with the supplied pole grease.
This measure prevents corrosion, but is not absolutely
necessary.
Check total battery voltage. It should correspond to the
number of blocks connected in series.
The open-circuit voltage of individual cells should not vary
more than 0.02V between them. The following maximum
deviations are permitted for block batteries:
• 6 V - Blocks: 0.04 V
• 12 V - Blocks: 0.05 V
Mount the supplied terminal covers to insulate the battery
terminals.
4.2 Battery sets in parallel installations
Conditions and characteristics for 2 to 4 strings in parallel:
To connect the battery strings in parallel, the battery connec-
tion distributor type BAE with integrated current shunt per
string must be used for battery string monitoring.
• The cable connectors for the positive and negative poles
of each string must have the same length.
• The minimum cable cross section for the end connectors
of a string is 25 mm
per 100 Ah string capacity.
2
• The end connector cables must end on a copper bar with at
least 100 mm
per 100 Ah line capacity and at the smallest
2
possible distance.
• Each string has a fuse.
