2) Set the multimeter to the voltage scale. Connect the negative pole of the probe to
the positive pole (in red) of the battery group, and the positive pole of the probe to
the negative (in black) of the battery group.
3) Perform different operations according different measured values as described in
Table 6-3.

4) Switch off the AC power supply and check whether the BTS3606A works normally.
5) Check the statuses of the board indicators to see whether the BTS3606A is
running properly.
If not, switch off the BAT switch. After the fault is cleared, power on the BTS3606A
again until it works normally.

6.2.4 Power-on Check of Integrated Equipment

Proceed as follows to conduct the power-on check of the integrated equipment:
1) Switch off all the power supplies on the AC power distribution box of the main
equipment.
2) Check that all the boards are inserted into slots.
3) Switch on the power supplies on the AC power distribution box sequentially and
power on the boards and modules sequentially.
4) Check whether the indicators of the boards and modules are normal.
If PWR indicator is on, the power supply is normal. If it is off, the power supply is
faulty or the indicator is damaged.
Indicates that the –48 V power cable and GND cable of
the battery are not connected properly. Connect them
properly and measure again.
Indicates that the cable connection is incorrect or the
battery is faulty. Connect cables correctly, clear battery
faults, and measure again.
Check whether long-term storage of the battery results
in self-discharge and low voltage. If yes, switch off the
BAT switch on the AC power distribution box and
perform the next step. If no, check whether the battery is
faulty. After the fault is cleared, measure again.
Indicates connections are correct. Switch off the BAT
switch on the AC power distribution box and perform the
next step.
