XIII.3.D. BATTERY CONNECTION
Since TW200 racks are used in the DS200L systems, battery connections are similar to the
ones in the DS200 systems. Feeding the system with sufficient amount of batteries is
essential, because the system capacity is higher.
Since the battery has been connected in parallel with the 48 VDC output of the external
power block, a battery group that has completely been exhausted may adversely affect
system performance. In that case, the battery group should be charged and then re-
connected to the system.
XIII.4. CABLING AND MAINTENANCE OF BATTERIES
Use of the 48V 24 Ah dry battery set (12V x 4), which needs no maintenance is strongly
recommended for the systems. The battery units that form the set are connected to one
another in series.
The cables that are to be used in all connections should be multi-core with 4mm
2
cross-
section. If the current rating of the battery to be employed is higher, then the cross-section of
the cable to be used is supposed to be proportionally larger. For instance, it is recommended
that the cross-section of the cable to be used be 16 mm
2
for the 200 Ah batteries. Tags in
appropriate sizes should be used at all the cable ends that are to be connected to the
batteries and those tags should be squeezed so tightly that is enough to eliminate any void
underneath.
The environmental temperature where the batteries stand should not be higher than 20-25
o
C.
Following the installation of batteries, a thin film of grease should be applied to battery
terminals.
