The DC power connection at your facility must be made by a qualified electrician, following the
instructions in this section. There are two 300W DC power supplies available: Model 10933
(recommended) and Model 10934A. The model 10933 can connect to both a +24V and -48V power
source.
NOTE
The connection instructions are different depending upon which type of power source you are connecting
to. The model 10933 can connect to both +24V and -48V sources, while the 10934A can connect to only -48V
sources.

Always make sure that the DC circuit is de-energized before connecting or disconnecting the DC power
cables on the 300 W DC power supply.

Provide proper connection and strain relief on the DC power cables in accordance with all local and
national electrical codes.
