ATTENTION

The JDX Direct-Drive™ must be powered with an isolated power

supply (either a separate power supply or a multi-out power sup-

ply with each output being isolated.)
If an un-isolated power supply is used to power the Direct-Drive

in conjunction with another device that is also using the same un-

isolated power supply the Direct-Drive will shut down as a safety

feature to prevent damage to the unit. Switching to an isolated

supply will correct the problem.
Should the unit shut down, simply un-plug it from the un-isolated

power supply and plug it into an isolated one as described above

and the unit will power up.
