4. Installation
This section provides further details regarding the connections that are made in
the process of installing the NBB.
4.1. Power Supply Connection
Connect the NBB unit to an appropriate power supply. The NBB’s Master
Power Switch must be "On" in order for the unit to operate.
To install the supplied "Cable Keepers", first, make certain that both power
cables are disconnected from your power supply. Next, loosen (but do not
remove) the two Phillips head screws located directly above each power inlet.
Connect the power supply cables to the NBB’s power inlets, then slip the
Cable Keepers over each supply cable, so the notch on the top of each keeper
secures each cable, and the two slots on the bottom of each keeper slide over
the loosened screws. Tighten the Phillips head screws to secure each cable
keeper to the unit, make certain the cables are secure, and then connect the
cables to your power supply.
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.
• Check nameplate ratings to ensure that there is no
overloading of supply circuits that could have an effect on
overcurrent protection and supply wiring.
