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.
