10 Mounting- and Operating Instruction CEAG DualGuard-S 40071860347 January 2020 www.ceag.de4 Preparations for battery installationAs can be seen from the calculation, no complex technicalventilation (e.g. explosion-proof fan) is required even whenusing the largest battery.Furthermore, due to the low-maintenance, leak-proof leadBatterys used, no special constructional requirements suchas electrolyte-resistant floor or floor covering (tiles, door sill)etc. have to be met.Sealed lead-acid Batterys can always be operated in anyposition (except head position).Determination of the aeration and ventilation of electricaloperating rooms in accordance with DIN EN 50272-2 (Cal-culated for heavy charge!):Batterykapazität in AhC10 At 1,8 V/Z and +20°C5.5 8.5 14.0 23.3 32.0 39.8 50.4 53.7 66.2 85.7 89.4 106.0 118.0 143.1 155.6 178.8 195.4 245.0 268.2 308.0 357.6Air volume flow req. for theventilation of the place ofinstallation [m3/h]0.24 0.37 0.60 1.01 1.38 1.72 2.18 2.32 2.86 3.70 3.86 4.58 5.10 6.18 6.72 7.72 8.44 10.58 11.59 13.31 15.45Vent cross-sectionof the air inlets andoutlets of the place ofinstallation [cm2]6.65 10.28 16.93 28.18 38.71 48.14 60.96 64.96 80.08 103.66 108.14 128.22 142.73 173.09 188.21 216.28 236.36 296.35 324.41 372.56 432.554 Preparations for battery installationCheck all blocks by measuring the open-circuit voltage.6 Volt block: U ž 6.33 V12 volt block: U ž 12.66 V• When measuring the open-circuit voltage, the correctpolarity (possible incorrect installation) must be observedat the same time.• If drawings were supplied by CEAG NotlichtsystemeGmbH, 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 levelsand 3 rows, the rack should also be firmly anchored in thebattery room.• Racks and cabinets should provide adequate ventilationabove and below to allow sufficient dissipation of theheat generated by Batterys 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 BatteryBlock SensorsInsulated tools must be used for the assembly work. Wearrubber gloves, goggles and protective clothing (incl. safetyshoes). Remove metal objects such as watches or jewellery.Mount the supplied battery block sensors Typee BBS, polecovers for insulation of the battery poles with the batteryconnectors. Tighten the battery connector with an insula-ted torque wrench. The following torques apply to screwconnections:• 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 NmAfter completion of the installation work, thinly coat theconnection surfaces with the supplied pole grease.This measure prevents corrosion, but is not absolutelynecessary.Check total battery voltage. It should correspond to thenumber of blocks connected in series.The open-circuit voltage of individual cells should not varymore than 0.02V between them. The following maximumdeviations are permitted for block Batterys:• 6 V - Blocks: 0.04 V• 12 V - Blocks: 0.05 VMount the supplied terminal covers to insulate the batteryterminals.4.2 Battery sets in parallel installationsConditions and characteristics for 2 to 4 strings in parallel:To connect the battery strings in parallel, the battery connec-tion distributor Typee BAE with integrated current shunt perstring must be used for battery string monitoring.• The cable connectors for the positive and negative polesof each string must have the same length.• The minimum cable cross section for the end connectorsof a string is 25 mm2 per 100 Ah string capacity.• The end connector cables must end on a copper bar with atleast 100 mm2 per 100 Ah line capacity and at the smallestpossible distance.• Each string has a fuse.
