How to use the PSB-2800LS
Description The PSB-2800LS is not equipped with a power
switch. The PSB-2800LS relies on a master unit to
turn it on when it is connected in parallel. As soon
as the master unit is turned on any connected
PSB-2800LS power supply is also turned on (see
page 70 for details).
In other words, the PSB-2800LS cannot be used
alone. So before using the PSB-2800LS, check to
make sure that the AC power cable, signal cables
and load wires are connected properly. Improper
wiring or settings may cause problems.
