Power

All of the devices attached to the Multi-Drop Box are normally powered through a common

power bus applied to the terminal block on the front of the box.

When power is supplied through the 4-pin terminal block, the input current must

not exceed nine amps.

Under some circumstances power may be supplied from a connected device. If power

is being supplied from a connected device, the input current must not exceed

two amps.

The terminal block requires DC VOLTAGE, appropriate for the devices hooked up to the

box and of sufficient current to run all of the devices. (See table below.)

Positive DC voltage must be applied to the socket labeled "POWER" and the power

ground must be applied to the socket labeled "GROUND". Connect the wires to the

terminal block by following the six steps previously listed.

CAUTION! Do not apply AC voltage to the Multi-Drop Box terminal block or to

individual units as immediate damage will occur!

Do Not power units individually through their AC/DC adapter jacks. Potential differences

between units could damage the power bus in the Multi-Drop Box or damage individual

units which may be supplied too much voltage.
