NOTICE
1. Each DC Power Supply has two RS485 interface female connectors. They need to be
connected either in series or parallel operation. There is no difference between left and
right; just to connect one after another as Figure 3-26 or Figure 3-27 shows in solid line.
2. Each DC Power Supply has two CURRENT SHARING connecting terminals in different
outline. Connect the output terminal of the first Power Supply to the input terminal of the
second Power Supply and so forth. Then connect the output terminal of the last Power
Supply back to the input terminal of the first as Figure 3-27 shows in dot line. Be sure to
use the CURRENT SHARING communication cable provided by CHROMA.
3. The CURRENT SHARING communication cable must be well connected when in
parallel operation, or it may cause the DC Power Supply to run abnormally or poor result
in CURRENT SHARING.
1. The DC Power Supply might be burned-out if the CURRENT SHARING input
and output terminals are connected incorrectly when in parallel mode.
2. Do not connect the CURRENT SHARING cable when in series operation or it
might be burned-out.
