Preliminary test of DC distribution and battery connection
Please connect the battery to the system according to the following steps.
1. Measure the battery voltage with multimeter and keep a record.
2. Turn on one rectifier, and set the rectifier voltage to a value with less than 0.5 V difference from the battery voltage
through the controller.
3. Use insulated tools, and connects the battery cables to the batteries according to the instructions of the battery
manufacturer. The other end of the battery cables have already been connected to the battery fuse as required in
3.2.6 Connecting Battery Cables.
Danger
Danger
Before access the battery, check with a multimeter that the battery polarities are correct. When connecting the battery, care ful
attention is required to prevent short circuit of the positive and negative poles of the battery. If two batteries are connected at one
time, battery mutual charging due to unequal terminal voltages of the two batteries should be avoided.
4. Set the power supply voltage to the required battery float voltage through the controller (in this case, the rectifier
should not be in current limiting state).

Setting dIP switches of PD380/400AFH and PD380/630AFH AC distribution cabinet
Bits 1 to 5 are used to set the addresses of the AC distribution cabinets. Position
‘ON’ represents ‘0’, and ‘OFF’
represents
‘1’. The setting explanation of bits 1 to 5 is given in Figure 4-1 to Table 4-1.
