Power-Up Check
1.
Plug in any DC wallpacks that are being used with individual intercom stations.
☞
If you plug in DC wallpacks after applying power to the PS2000L, you may
get an overload indication at the PS2000L. This is because the stations that
are being powered by wallpacks will draw current from the PS2000L until
their own DC supplies are connected.
2.
Plug in the AC power cords for any connected PS2000L Power Supplies. The
channel status indicators should be green.
3.
If a channel status indicator turns red during operation, try correcting the prob-
lem by pressing the reset button on the front of the PS2000L. If the problem per-
sists, unplug the PS2000L and locate the short or overload that is causing the
problem.
