This section provides further details regarding the connections that are made in
the process of installing the NBB.
4.1. Power Supply Connection
Use the supplied power cord to connect the NBB unit to an appropriate power
supply. The NBB’s Master Power Switch must be "On" in order for the unit to
To install the supplied "Cable Keeper", first, make certain that the power
supply cable is disconnected from the NBB unit. Next, loosen (but do not
remove) the two phillips head screws located directly above and below the
power inlet. Connect the power supply cable to the NBB’s power inlet, then
slip the Cable Keeper over the over the supply cable, so the notch on the top
of the keeper lines up with the cable, and the two slots on the bottom of the
keeper slide over the loosened screws. Tighten the phillips head screws, check
to make certain that the cable is secure, and then connect the other end of the
cable to your power supply.
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.
4.2. Connection to Switched Outlets
Connect the power cord from the Switched Device to a Switched AC Outlet
on the NBB unit. Note that in the default state, when power is applied to the
NBB, the Switched AC Outlets will be switched "ON". The NBB-115 can
switch up to a total 15 Amps, and the NBB-230 can switch up to 10 Amps.
