Mounting and Operating Manual
Central Battery System EURO ZB.1
17
CEAG Notlichtsysteme GmbH
Fig. 14: Charging characteristic
Remarks:
No gas will escape under normal charging conditions. Distilled water
for make-up purposes cannot be filled in since the batteries are perma-
nently sealed. Higher temperatures will shorten the battery service life
(cf. „Battery operating temperature“ on the preceding page).
Attention!
Batteries for emergency operation must only be stored for a period
not exceeding three months without being charged!
If the mains power to the EURO ZB.1 central battery system is in-
terrupted for more than three days the battery circuits must be
disconnected (remove battery fuse). This work must exclusively be
performed by skilled electrical personnel (cf. „12.5 Testing / Replacing
Fuses“).

Tending and Checking Batteries

Inspection
The following minimum inspection instructions must be observed to ensure the full
service life of the batteries. In case of records being incomplete and/or failure to
carry out battery inspections the warranty may become void or legally ineffective.
The following shall be measured and recorded at least every 6 months:
1. Voltage of individual battery blocks with charger being switched off.
2. Floating operation voltage of the individual battery blocks.
3. Floating operation voltage of the battery system.
Annual checks:
1. Semi-annual inspections must be repeated.
2. All connections must be checked for cleanliness, continuity and resistance.
3. All connections must be retightened as recommended using a torque wrench.
4. Checking the set-up and accommodation of the batteries.
5. Checking ventilation effectiveness.
6. The batteries must be discharged and their condition inspected as prescribed
by VDE 0108.
Please only use leak proof batteries!
Battery charging
The low-maintenance batteries offered by CEAG are properly charged to suit tem-
perature requirements and according to the adjacent I/U charging characteristics.
To suit the respective battery charging condition high-rate charging (via charging
modules) is carried out so that the batteries are quickly charged without the gassing
voltage being exceeded.
The charging supervision process serves to permanently check the charging opera-
tion and immediately report faults such as battery circuit interruption, defect charger
unit or high-resistance cells.
Note:
When battery is taken into operation make sure that the float charge voltage
is according to manufacturers information.
