System Ground
The rear-panel System Ground black banana jack is intended for one use only. When the EIS Box is used with
cells isolated from earth ground, connecting the System Ground to earth ground may lower the noise measured
in the system. Note that the chassis of the EIS Box is connected to the Protective (earth) Ground . Safety
information concerning this is in Chapter 1.
Use a metal link to connect the Protective Ground to the System Ground as shown above.
Protective Ground
The green Protective Ground binding post is a convenient access point to the protective (earth) ground in the
EIS Box . It is connected to the third wire in the AC power cord and to the EIS Box’s metal chassis. This binding
post can be connected to an additional earth ground to form a redundant protective ground.
A black banana-plug-to-banana-plug lead is provided with your EIS Box. You may find it useful when making
the earth-ground connection (if a redundant protective ground is required).
Ethernet
The Ethernet port on the rear panel of the EIS Box is a receptacle for an RJ-45 ethernet cable. Use a standard
ethernet cable with RJ-45 connector to connect this port to a computer
’s ethernet.
A suitable ethernet cable was included with your EIS Box. If this cable is lost, you can replace it with a cable
from your local computer retailer.
