If possible, the 9020-OEM and 9020 should be grounded to the system ground in order to
maximize noise immunity. For the 9020-OEM, the ground lead should be connected to the
SHIELD stud where the cable shield is terminated. For the 9020, a separate ground stud is
located directly adjacent to the probe cable gland on the bottom of the enclosure.
A two-conductor cable with shield is recommended for wiring to the 4-20 mA. connections.
If only corrosion rate measurement is required, the connections are made to the two- position
terminal strip labeled CORROSION. If only imbalance measurements are required, the
connections are made to the two-position terminal strip labeled IMBALANCE. If both
measurements are required, connect to both two-position terminal strips as described above.
It is recommended that the shield for the 4-20 mA. loop(s) be grounded at the receiving end,
but left un-terminated at the transmitter end.
