This section describes the installation procedure for the NPS hardware.
Note:
For a detailed description of configurations options and advanced
operating features, please refer to the WTI Firmware Guide.
4.1. Connecting the NPS to Your Power Supply
CAUTIONS:
• Before attempting to install this unit, please review the warnings and
cautions listed at the front of the user’s guide.
• 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.
• Some NPS models include two power inlets to allow connection to
multiple power supplies.
4.1.1. Installing the Power Supply Cable Keepers
The NPS includes cable keepers, which are designed to prevent the power supply
cables from being accidentally disconnected from the unit.
•
NPS-8HD Series Units:
Cable keepers must be installed by the user.
1. First make certain that both of the NPS’s two power cables are disconnected
from the power source.
2. Install the two standoff screws (included with the cable keeper) in the two
vacant screw holes, located between the two power inlets. When the standoff
screws are in place, thread the two screws supplied with the cable keeper into
the top end of both of the standoff screws.
3. Connect the power cables to the power inlets. Check to make sure that both
cables are firmly seated in the power inlet connectors.
4. Install the cable keeper plate, by slipping the plate over the two screws which
protrude from the top of the standoffs. Slip the cable keeper plate into place,
so that the notches in the bottom of the plate slip over the power cables, and
the holes in the middle of the plate align with the screws in the tops of the
standoffs.
5. Tighten the two screws into the standoffs to secure the plate and the power
supply cables to the unit. Check to make certain that the cables are held firmly
in place by the cable keepers.
