4. Hardware Installation
This section describes the installation procedure for the NBB hardware.
Note:
For a detailed description of configurations options and advanced
operating features, please refer to the WTI Firmware Guide.
4.1. Rack Mounting
The NBB offers three different mounting options; the unit can either be mounted to
the equipment rack using the supplied Mounting Buttons or Mounting Plates, or the
optional Mounting Brackets. For more information on rack mounting, please refer to the
instructions in Appendix C.
4.2. Connecting Power to the NBB
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 NBB models include two power inlets.
4.2.1. Connect the NBB to Your Power Supply
Refer to the cautions listed below and at the beginning of this User's Guide, and
the information on the instrument name plate, and then connect the NBB unit to an
appropriate power supply.
Note:
Some NBB units are shipped with one or two detachable 125 VAC,
15 Amp "Starter" Cables. These cable(s) will allow you to connect a 120 VAC
NBB unit to power for bench testing and initial start up and are adequate for
applications that only require 15 Amps. For higher amp power switching
applications, please refer to the WTI Power Cable Guide (which can be found at
https://www.wti.com/guides/powercables_refguide.pdf.)
4.2.2. Installing the Power Supply Cable Keepers
NBB series units with removable power supply cables include pre-installed cable
keepers. When attaching the power supply cables to the unit, first swing the cable
keepers out of the way, then plug the power cables securely into the power inputs.
When the cables are in place, snap the cable keepers over each plug to secure the
cables to the unit.
