4. Installation
4.1. Power Connection
Note that the NPS-2HD features two separate 20 amp buses. In
order for both buses to function, power must be connected to
both input connectors on the unit's back panel.
Prior to connecting power supply cables to the unit, please refer
to the cautions below, and the cable clamp installation
instructions in Sections 4.1.1 and 4.1.2.
CAUTIONS:
•
This device should only be operated with the
type of power source indicated on the
instrument nameplate. If you are not sure of the
type of power service available, please contact
your local power company.
•
Reliable earthing (grounding) of this unit must
be maintained. Particular attention should be
given to supply connections when connecting to
power strips, rather than directly to the branch
circuit.
"Always On" Architecture: The NPS-2HD features "Always
On" architecture. This means that once the NPS-2HD is
connected to your power supply, both plugs will always be set in
the ON state, unless program commands or the Manual Control
Buttons have been used to switch the plug(s) to the OFF state.
4.1.1. Cable Clamp Installation
CAUTIONS:
•
Make certain that the unit is disconnected from
the power source before beginning this
procedure.
•
In order to reduce the chance of injury due to
electric shock, the Output Cables should be
installed before the Input Cables.
