Hi,

Sorry i forgot to mention: have a JRC NRD 545

You're undoubtedly correct.
Why, though, provide an additional ground connection off of the barrier /
terminal strip ?

You can opt to use a ground lifter on the power cord and single-ground
the unit to a better ground via the ground terminal. Especially in a
facilitiy where the electricity mains are not in EMT and the ground
wire is a 12 g wire snaking through 50 or more feet of walls to a
breaker box.
