5.9 Installing Built-in Batteries

Caution:
Before connecting the battery cable, turn off the BAT switch in the DC power
distribution subrack of the BTS3606A cabinet.
Disconnect the fuse before connecting the batteries. Avoid the occurrence of short
circuit when connecting the cables. Connect the –48 V cables first and then the
GND cables.
Before powering on the cabinet, check whether the batteries are well connected. If
not, use the heat-shrinkable tubes to protect the naked terminals between the PMU
to the –48 V GND and between the fuse to the –48 V power cable of the battery.
Otherwise, short circuit might result.
BTS3606A built-in batteries are four 48V, 65 Ah batteries.
To install the built-in batteries in the battery cabin, proceed as follows:
1) Loose the screws on the cover of the built-in battery cabin.
2) Remove the cover and save the screws for later installation.
Now, you can see that the temperature monitoring cable, the GND cable, and
–48V cables with OT terminals are pre-installed inside the cabin, as shown in
Figure 5-46.
